Mechanical Drafting

The Importance of Mechanical Drafting for Emerging Architects

What is one thing modern architects and designers are giving up entirely? The answer is mechanical drawing and drafting skills. It is no doubt the 21st century, and we are living and breathing technology. Digitalization and software skills are ruling the roost for efficiency and adaptability.

However, what any good architect or senior associate with let you know is that communication is the bedrock of your design, apart from the foundations that you draw for your building of course. As young mechanical artists, most of the students have rarely, if ever drawn by hand. Computer and iPads having drawing and visualization software and versatile stylus have made it even easier to have designed on your digital fingertips.

What we have to consider as emerging Architects is that without hand drafting skills and practice, one is missing out on the tactile education that integrates design, elevations, angles and visualization skills into our subconscious mind.

Picture a scenario where you are in a meeting with a potential client in the Mechanical Design outsourcing company you work in. They have an idea in mind while you have some modification in your head, and both of you need to communicate the visual aspects of the design to reach a middle ground. And most of all, this is a crucial point where you can gain your client’s trust in your designing aptitude and eye for detail. In such a situation, you can quickly sketch out a draft of the visual in your head, giving a view from 2-3 angles, detailing the important components that the client was trying to understand, and negotiating all minor changes in the design that pops up on both your and the client’s head while looking at the sketch. This is not something you could have achieved with a moment’s notice on mechanical design software. Nor is it something that software can reproduce to give you credibility and value in your client’s eye. Your individuality and visualization power stand out when you draft a design by hand.

The Drawback in Computer-Aided Mechanical Designing

A computer can never replace the raw conceptualization and communication that an architect can render by hand. A computer-aided program like AutoCAD or mechanical CAD design services does make the design workflow easier and more detailed, but it makes the architect lose out on their integral drawing skill. Since any computer-aided mechanical drafting software can make it easy to integrate changes or load templates, it is easy to give in to the comfort of not having to conceptualize and draw a design by hand. The designer loses their credibility.

Hand drafting is one of the quickest and surest ways to learn line drawing, understand perspectives, scale and establish a meaningful relationship with the creation you made on paper. Drawing by hand, feeling the hand flow around the paper, giving angles, shading, appreciating the space and scale without the luxury of scrolling out of frame. None of these is possible with computer-aided designing.

Emerging Architects and young intern architects should learn to appreciate and comprehend the basics that go into the building of a whole project. Starting small from drawing and understanding sectional drawings, elevations and sketching to pen down ideas is a great way to integrate design principles into the mind. Have you ever noticed how engineers or architects tend to draw at the back of an envelop or the back of the rough paper to explain small designs or concepts to others? This just shows how natural it feels to the brain to communicate design by hand.

One of the most important skills one needs in this trade is the ability to solve problems. When working in teams and peers, a young architect might not be able to develop their comprehension and conveying skills like their previous generation of architects. What computer-aided drafting software might not teach you is how to look at any object and instantly visualize and render it from all sides, elevations, sections and details.

Reasons why Mechanical Drafting is Important

Not just the technical skill of being able to draft mechanical drawings, engineers and architects are also taught communication of concepts by hand. Here is a breakdown of the technical and psychological reasons that drawing by hand should continue being an important part of the learning curve for young interns and emerging architects:

  1. Sketching/Drafting is a form of graphical representation that teach skills and service needs that are not developed when using computer-aided drafting entirely
  2. Drawing/Drafting is still the most preferred form of representing external data by senior associates and architects. The reason for it can be further understood as:
    • Diagrams preserve geographical and topographical information. It allows us to easily index and labels information that can help in the computation process
    • Mechanical drafts are able to group multiple subgroups of information into a single diagram and visual. It helps to understand the correlation of elements in the drawing and knowing how it will join to form the larger picture after computerization instead of leaving it entirely on the software itself.
    • Diagrams can use a large amount of perceptual information, that cannot be understood in detail if rendered directly on the software
  3. Drawing is a basic cognitive capability that an architect requires for mental stimulation, representation of data that he sees on a daily basis, externalizing the visual imagery that pops up in their mind when asked to think up solutions to a construction project.
  4. Mechanical drafting is required so that an architect can render the idea in their head to an external memory medium too. Transforming hand-drawn drafts into CAD design requires one to know the basics of how line drawing and scaling works. The cognitive skills or process underuse when drawing a line by hand is different than rendering a line on AutoCAD or other drafting software.
  5. Mechanical Drafting showcases the concept and cognitive ability of an architect, which is independent of their drawing’s characteristics. It builds trust in themselves and their clients when they can determine the design features required to bring an idea to life on paper, or later on a mechanical drafting software.

In conclusion

There is evidence in the research done, the experience and success stories of senior architects and designers, as well as in cognitive psychology that drawing by hand is important in shaping a sound, skillful and ready-to-take-on-challenges architect.

Drawings have always been the ideal way of representing data and components in any building or design process. And it cannot be denied that it plays an important role in the design process.

Mechanical drawings are the window to an Architect’s soul. It forms the basis of their problem-solving abilities and their communication powers. No matter how technology eases life ahead, any upcoming architect needs to be grounded to their roots of handmade mechanical drawings.

BIM and CAD

What is the Difference Between BIM and CAD Files?

To understand the difference between BIM and CAD files you must know the concepts of BIM and CAD files and what are their uses.

CAD stands for Computer-aided design whereas BIM stands for Building Information modeling. Computer-aided design programs are used by engineers to assist with the creation, modification, analysis, or optimization of designs with the use of computer systems such as TinkerCAD, Autodesk’s AutoCAD, etc.

BIM is an acronym for Building Information Modeling. BIM is a new-age process used by architects, engineers, and construction professionals to design and construct buildings and infrastructure more efficiently.

CAD and BIM files have different uses and differ in many ways. You cannot replace one with another. To know the difference let’s understand the concepts in details.

 What is CAD and who uses CAD?

CAD is a highly decorative program that is used in the creation of making 2D drawings and 3D models using computer systems. The 3D AutoCAD CS software has been used by these engineers for decades helping them to design and manufacture complex products efficiently and effectively saving a lot of time.

CAD was developed back in 1963 by Ivan Sutherland that broke new ground records in 2D and 3D modeling and visual simulation. Engineers could directly draw on a CRT with the use of a light pen.

CAD programs are widely used by engineers in civil engineering and plant design in various industrial and manufacturing companies. These widely used computer software programs can help you explore and design ideas through photorealistic renderings and simulate how a design performs in the real world

Advantages of CAD

  • Easy to use, edit designs and modify drawings using computer-aided software
  • CAD models offers improved accuracy over manual drawings.
  • When a certain part or aspect of the drawing is required, duplication of labour is removed as everything is available and reproducible digitally
  • CAD software has a paper trail to refer back to automatically for any digital design you make

Disadvantages of CAD

  • May cause complacency as designers slip into the same design from their library each time and cause your designs to look the same
  • CAD allows different aspects of design to be put together but leaves out the bigger picture and the real-world issues of the design when doing so

What is BIM and who uses BIM?

BIM is an advanced 3D model-based program mainly used by architects, engineers, and contractors to design and build commercial buildings and infrastructure. With the help of BIM files, you can analyze and evaluate design decisions before starting the project.

BIM works as a single communication channel between work process and technology to work on the project collaboratively and efficiently. BIM is a digital 3D model based representation and shared resource that can be used by multiple parties involved in the design and build the structure from the beginning till the end.

This 3D model-based representation makes itself a cost-efficient and time-saving process and the chances of making errors are minimal and if any, that can be discovered at an early stage. BIM model provides data that can span the operation and management aspect of the construction project, and this information is later available to the structure owners as well.

Nowadays BIM is being commonly used by manufacturing engineers and contractors to provide a piece of detailed product information in different BIM formats. BIM software tools (the most common one being Revit) have redefined the design and construction workforce amongst the architectural and engineering design firms as well as contractors.

To know more about BIM modeling and using BIM solutions to make your construction project efficiently smoother, reach out to us at Monarch Innovation.

Advantages of BIM

  • Teamwork is enhanced as communication across all construction phases and techniques is coordinated
  • Any change made to the design either individually or simultaneously by different team members is dynamically shown and monitored
  • Even at the planning stage, the final structure or its components can be visualised
  • Any clashes between different sets of data in regards to components or between contractors can be identified and sorted before any cost is incurred in reversing the change.

Disadvantages of BIM

  • BIM software requires initial software investment and powerful PCs for processing
  • Staff and engineers need to be trained in BIM to make full utilisation of its features across projects
  • Although it might now sound like a big deal trust and change in work culture is a big issue for various teams working collaboratively on the project to make the most of their data. All parties need to be willing to share the data and invest in understanding its importance
  • The client often has no idea of the superior features of BIM modelling and don’t utilise the information presented by BIM to the full extent, wasting the time and effort of the construction team

CAD usage and How Does It Compare To BIM?

CAD models have been useful for a long time to help the architect to understand and render the modifications, development and optimization of the entire construction process. CAD has replaced manual drafting and helped the engineers, architects, and construction managers in creating designs in either 2D or 3D models so that they can visualize the construction of the project.

With the help of CAD now it is easier to make more accurate representations and modify them to improve design quality. It also helps the subcontractors to add up more details to the model.

Nowadays you can create a backup of your drawings and plans in the cloud storage which can be easily accessible by the contractors to CAD-based drawings/plans at the worksite making plan out the modifications easily. It also helps to identify the possible impact the changes might have on construction and adapt as needed and improves communication. This ultimately increases productivity and the effective utilisation of information.

Designers can now create more comprehensive designs considering other elements like electricity, plumbing, structure etc. which has only been possible with the help of CAD. This ultimately enables fewer work changes and a reduction in errors. The technological impact of CAD has been a game-changer in the industrial markets transforming construction into a technology job.

Many Engineers and contractors have been anticipating that these new-aged BIM software tools will become the focus of every new commercial building projects due to its collaborative process that allows architects, engineers and other constructional professionals to construct or design within a single 3D model.

One of the largest upgrades on BIM software from previous CAD software is that BIM allows work in 5 dimensions – time, cost, length, breadth and width. CAD allows work in only length, breadth and width. One can easily understand how this is a game-changer in the construction industry across project teams.

Today’s architects and engineers rely on BIM software to build and design 3D models of their buildings and infrastructure. The power of visualizing something in 3D gives the design and construction team a pretty accurate estimate of what the final structure should look like as well as the cost estimations along the way.

BIM Vs CAD – Which to Use?

CAD is mainly used for industrial design of mechanical and electrical work such as aeroplanes, mobile phones etc. On the other hand, BIM is used in the design and manufacturing of buildings and infrastructure such as airports, schools, hospitals, etc., and has become the most preferred software in the industrial markets. These files also give you the feature to detect virtual collision and construction-related errors before starting the actual work.

BIM models are designed for flexibility i.e., you can zoom in and zoom out and make a detailed design of your building. CAD is more likely a static, high-detailed component that has only one visual representation. A changeable BIM model will enable the CAD file to be viewable in its original form with full detail up to a definite zoom level.

Converting CAD files to BIM file types can result in blurring of CAD components while adjusting the scale of the model whereas adjusting the scale further can cause the image to discolor, appear as a black splotch, or fade from the screen. Hence CAD files fail to self-correct these adjustments when they are incorporated into BIM files.

CAD to BIM conversion – what are the advantages?

Although CAD has ruled the roost for a long time, it is now time to hand over the throne to Revit BIM models, which offer a far larger set of advantages. A lot of CAD designs are being converted to BIM models for high-rise or large scale construction projects because:

  • BIM models are more detailed, provide more options for analysis and deconstruction of the data.
  • BIM allows work in 5 dimensions – time, cost, length, breadth, and width. CAD allows work in only length, breadth, and width.
  • BIM models are easier to manipulate and use to incorporate new changes and design integrations.
  • Revit is a software that is now widely used, making it easier to communicate between stakeholders and project teams.
  • BIM models help in scheduling the timeline of the construction stages, estimating the cost, and billing the quantities of each component
  • BIM modeling can cover the whole lifecycle of the project – right from the design conceptualization to construction to demolition.
  • As all the information is pooled at a common spot and changes can be made dynamically, it dramatically reduces the loss of information across the pipeline, and increases efficiency.

What are As-Built drawings in the Construction Industry?

As-Built Drawings

There is rarely ever a situation where the blueprint drawings on paper match the real-world structure exactly the way it was designed. As-Built drawings reflect the actual structure or space that gets built.

As-Built drawings are drawing records that reflect the changes made during the entire construction process of a project. They say a picture speaks a thousand words – And in any construction project, there is no better way of keeping updated track of the multiple parallel steps than As-Built drawings.

According to Business Dictionary, As-Builts are a “revised set of drawings that reflect all changes made in the specifications and working drawings during the construction process. It shows the exact dimensions, geometry and location of all elements of the work completed under the contract.”

These drawings are usually addressed by the contractor at the end of the project. As-Built drawings are an essential component in the lifecycle of the project but they tend to get overlooked until the very end because way too many steps and changes need to be recorded. This might lead to lapses in the final project looking exactly like how it was initially planned to be.

In this article we get into the details of why As-Built drawings are important, who designs them, who can manage and access the data, how should they be utilized, and what are effective strategies to make the best use of As-Built drawings in the construction industry.

For more knowledge and professional guidance on how to set up and manage your As-Built plans for your construction project, reach out to us at Monarch Innovation.

Who are As-Built drawings created by?

The architects and designers who are responsible for the framework and detailing of the entire project are best equipped to create As-Built drawings. Once created and maintained by architects/designers, it is then managed by the contractor on site. It makes sure that the construction drawings and resources do not merely exist in the original blueprints drafted, but beyond the lifespan of the project too.

Even if ownership of the project changes or the set of employees are replaced in the duration of the project, the As-Built drawings help in getting familiar and keeping track of the progress in the plans. Any future modifications or new construction can be continued on top of the work already accomplished.

What do As-Built drawings need to include?

There is no standard on what should be the expected output of an As-Built plan. It varies in the eyes of various contractors depending on the expectations they have from the data in the As-Built construction. To make the progress on the project clear and useful, As-Builts can include certain details such as:

  • Record the scale measurements used in original drawing constructions, and further changes made to it, if any.
  • Include changes made to length, dimensions, orientations, fabrications or location of any component of the construction process
  • Making note of the date when changes are made
  • Making note of any obstacles in the execution of original blueprints, and what was the solution made in place of it
  • Include original shop drawings and record any changes made to them
  • Any additional work done on the project that is extra to the originally planned drawing construction

Why are As-Built Drawings important in the Construction Industry?

As-Built construction plans are important at each step of the way and to each of the shareholder in the process from start to end. Here’s how:

  • Contractors require As-Built drawings to record the transition from one phase of the construction to the next. They can then visualize the steps needed to take further, and issue actions to the workers accordingly.
  • If obstacles or issues occur during the construction process, As-Builts can be referred to identify the last step and resolve it
  • If constantly being updated, As-Built drawings help identify a foreseeable complication and can be resolved before they happen.
  • Owners or clients of the property can refer to the As-Built documentation to check for the installations or designs being included, and ask to modify them if they face any issue with it.
  • Property buyers need As-Built drawings to understand what exactly they are buying or selling. They can also use it as the basis of any future renovations and installations.
  • The renovation process is made easy when the detail of what is already done is available. It saves expense incurred in learning about the existing setup before making additional changes.

Traditional vs. BIM As-Built Construction

The traditional method of maintaining As-Built drawings lacked coordination and precision updates from the different segments working on the project at the same time. This lead to delays in communication as well as fragmented management.

The major problem faced in the traditional method was the rework that needed to be done each time to update the data. This delay led to disruption in the flow of communication between different phases of the work which further led to an increase in overhead costs and time. This was also one of the reasons why As-Built drawings were usually overlooked until after the project had already taken the final shape.

In comes BIM (Building Information Modelling) and construction management software. They effectively overcome most of these problems while providing additional features and advantages to As-Built construction.

  • Workflows can now be automated and pre-scheduled, and multiple workflows visualized at a time
  • Collaborations are made easier between different professionals overlooking different aspects of the project.
  • Better and richer quality As-Built data can be uploaded, stored and accessed simultaneously through cloud-based systems.
  • BIM visualization can identify the clash in spatial orientations beforehand, which saves the waste of traditional documentation
  • Clients can get a visual tour of the entire project even while it is getting built, identifying issues and pointing out changes they need in real-time.
  • Different teams can work together and make qualitative decisions based on the date easily accessed to everyone simultaneously, saving time and overhead cost
  • Good construction management software help the project reach completion faster and in a more sustainable manner

How to improve your As-Built Construction Strategy?

Here are a few guidelines to keep in mind for the most effective use and construction of As-Built drawings:

  • Set up As-Built systems before construction begins, not at the end

This will allow an integrated space for simultaneous data capture, storage, editing and distribution right from the time the project starts.

It also allows teams to upload and digitally access different sets of data in real-time from various devices and at different times, without having to wait to get back to the office to make field documentation.

  • Make the team understand the importance of As-Builts

A work culture of understanding why data capture and storage is significant needs to be created before the project starts. How to create As-Builts, the steps followed along the way, contractor expectations and end-goals should also be discussed and implemented.

  • Go deep with the data

Technology like Laser scanning, BIM visualization, O&M software should be exploited to the full extent for making As-Builts. The more capture of data, the better. This helps the team get deeper insights into data, resolve issues before they occur, and reach the goals faster and in a more cohesive manner.

10 Major Types of Construction Drawings Used in Building Construction

Types of Construction Drawings

Construction drawings are used for a wide variety of reasons and applications in construction and architectural projects and activities.

What is a construction drawing?

It is a graphical representation of what will be built, how it will be laid out, the components, framework, and dimensions. There is a construction drawing highlighting the details for every aspect of a construction project.

Construction Drawings including each of its subtypes are helpful to different groups of workforce assigned with doing or overlooking the various tasks that make up a construction project.

How are construction drawings made?

Rarely are construction plans drawn by hand anymore. They are either sketched and rendered using computer-aided drafting such as computer-aided design (CAD) software. And in recent times, Building Information Modeling (BIM) software has made it easy to render and visualize in detail the virtual construction models (VCM).

To know more about BIM services, budgeting, and how they can benefit your project, reach out to us at Monarch Innovation for all queries, assistance, and collaborations.

Top 10 most common types of Construction drawings use regularly in construction industries.

1. Block Plan

This drawing gives a layout of the site or the buildings in the surrounding area, laid out on a map drawn to scale.

  • It gives a firsthand idea of the roads, boundaries and other such details that are necessary to understand where your construction site lies.
  • It helps the person dealing with your construction plan or project request to understand what and where you are proposing it and help you out with it too.
  • Block plans are made in relation to Ordnance Survey Maps and the recommended scales used are 1:2500, 1:1250 or 1:500.

2. Architectural Drawings

Architectural Drawings are drawing work that is used in building drawings to depict the dimensions, depth, and layout of the actual building, prior to beginning the construction. Architectural Drawings act as a blueprint construction, drawn to scale, to help the engineers visualize the project.

Various types of Architectural Drawings commonly used are:

  • Foundation plan – not to be mistaken for just the ground or basement floor plan. Foundation Plans are drawing work to render any of the floors of the building being constructed. They help visualize the dimension, size, shape, height and configuration of rooms/stairs/landings with each other.
  • Floor plans – in-depth rendering of the layout of the rooms for each floor. It describes in 2D the orientation of rooms and components to each other. Floor plans may or may not be utilized in commercial or non-commercial building projects, but it is necessarily still made as part of the drawing work.
  • Sectional Drawings – these are drawings that depict a part or whole of the framework in sliced form. It helps understand the measurements of various building components with each other, the materials used in the construction of those components, the height, depth, and hollowness, etc.
  • Elevation Drawings – these architectural drawings offer an aesthetic overview of the various components of the building such as columns, windows, and doorframes. It also helps understand the relative surface, internal markings, and relative height of these different components to each other.

3. Production Drawings

These Construction Drawings are used to convey functional information to the workers and engineers on site. It describes the materials, the assembly of various parts, the tools required, the dimensions, and other information required during the process. It may also include additional information or an infographic on how to meet those set requirements.

4. Structural Drawings

Structural Drawings also serve as civil engineering drawings. They are useful in understanding the physical nitty-gritty of a building framework. They act as a structural design guide for the workers and on-site engineers. Common types of structural drawings are:

  • General Note – an overview of all the codes, procedures, and abbreviations, etc required to give a comprehensive guide to getting to work on the construction site. This includes concrete mix, details for other structural drawings, lengths and construction types of each component, etc.
  • Excavation Drawing – this civil engineering drawing describes the dimensions and positions for the excavation process prior to the actual building work. It covers details like tunneling, shafts, removal of soil, grid plans, etc required to start the groundwork.
  • Column Layouts – These structural drawings include the layouts of the way columns will be laid out. It makes it easier for contractors to plan the layout of the building and start the process by identifying the position and distance between columns across the floor.
  • Beam Layouts – It includes all the beam-like structures, such as the ones supporting the roof and the windows, or the beams used for strengthening purposes. They are designed for each floor and cover the length, height, material, etc.
  • Roof slab layouts – this civil engineering drawing describes the exact dimensions of all the slabs required for roofs or slants. It can be designed over AutoCAD software as it requires precision and data.

5. Electrical drawings

Most residential construction drawings or commercial construction drawings require a functional outline of the number of power outlets, light fixtures, fan fixtures, etc. They also include the wiring pattern and details about the electrical load it can carry. Common details included in Electrical Drawings are:

  • Earthing layout
  • Light fixture layout
  • Generator and other equipment
  • Cable tray layout
  • Hazardous area classifications
  • Lighting protection system

6. Plumbing Drawings

Just like electrical layouts, plumbing is another part of any residential or commercial construction drawing that marks the points where plumbing components need to be set up. Space is left here accordingly for further pipe and sanitary ware fixtures to be added once the structural component is finished. Plumbing drawings commonly include:

  • Pipes water pipes, drainage pipes, internal pipes
  • Material of pipes
  • Outlet points – taps, sinks, tanks etc
  • Position and location of pipes and outlets

7. HVAC Drawings

These are known as mechanical construction drawings. They provide details and a design framework for heating and ventilation systems in a building. Central heating/cooling, air conditioning vents, ventilators, etc are all included according to the need and site of the building plans. Builders use these design constructs in their process accordingly.

8. Firefighting Drawings

In today’s construction systems, safety design is paramount. Firefight Drawings are also a part of blueprint drawings of a building that allocate points for fire hoses, fire escapes, water outlets, sandbags, or any other fire safety equipment required by the regulatory body overseeing the project.

9. Environmental Plans

Making sure environmental guidelines and management is properly followed is a part of construction projects that cannot be overlooked. The aim is to minimize environmental damage and future negative impacts of the construction project. It includes measures like:

  • Chemical disposal mechanisms
  • Management of erosion and sedimentation
  • Outlining environmental guideline compliance measures
  • Measures to handle accidents and emergencies like fire

10. Finishing Drawings

These include finer and more detailed plans of the building after the whole structural and architectural framework has been set up. These are required for the aesthetic and functional value of the building. These construction drawings include details of:

  • Tile patterns,
  • Floor patterns
  • False ceilings
  • Paint colors and textures
  • Plaster
  • Woodwork
  • Motifs and designs

WORKING WITH LARGE ASSEMBLIES – PROJECTS OR INFERIOR HARDWARE

Don’t want to go into detail, just jump to a line with #Instant. (For the first time in blog history.) I want it to be useful for both beginners and professionals. So I will start with some basic fundamental about how software works and then will move forward to possible improvisation scope based on that. Basically, I am going to publish series of blogs, which will cover different CAD software. In this part, I am going to focus more on some general improvements. Normally people want to buy high-end hardware to increase performance and reduce time but it is not always true. One need to judge that based on the type of work. At the end, it is all about getting best out of what you have. So let’s have a look at how we can achieve that. Difference Compared to other Blogs : You will find a number of blogs / Help topics related to the same topic which will guide you regarding ways to improve performance. Indeed, those are very useful and I have also gained knowledge from that. But major blogs /help topics don’t mention how to judge whether one has to upgrade hardware or not and if yes which part needs to be updated. The user needs to judge that based on their requirement. I will help you decide that. Main components of computer which directly affect performance of any CAD/CAM/CAE software are Processor Motherboard RAM Graphic Card Storage (HDD/SSD) Network Environment (for Intranet and Internet) Operating System Workstation : To avoid compatibility issues and to get driver support for new operating system and CAD software, (#Instant) we always prefer to buy a system from the manufacturer (Dell, HP etc) and don’t go for assembled computer by a local vendor. Certified hardware will obviously perform better due to tight integration with other hardware. One should consider this only when the computer is taking more time than one need to spend a time to give instructions to the software. Motherboard & Processor : As mentioned on Autodesk website, (#Instant) The wisest choice is to procure the fastest single CPU that your budget allows. If your budget allows, buy the fastest Multi-core CPU and suitable motherboard. You need to go into detail to understand your requirement. Let me give you some insights of software. All CAD software are not multi-thread software. In laymen language, CAD software is not designed in such a way that it can give instruction to multiple cores. As a developer I can understand, it’s a big task to program in such a way. However, CAD Software uses multicore during some processes such as rendering, Animation, raytracing, Stress Analysis, Hidden line calculation in drawing etc. For more detail refer article Support-for-multi-core-processors. If you are using any process mentioned in that article you should opt for a multi-core processor. Let us take one example to make it clearer. e.g. If one need to create drawing with more than four views, obviously multicore is helpful. But if views are very complex and drawing has few views then one should opt fastest single CPU. (#Instant) Apart from that, if you already have multi-core processor then you can take advantage using multiple instances of the CAD Software. I personally open another inventor for reference model as the operating system can run the second inventor on other core. It is not advisable if you are running out of RAM, as it requires more RAM. RAM : Higher RAM is always better but only when you need that. The easiest way to check the same is by monitoring resource monitor or performance tab of Task Manager. (#Instant)As a thumb rule, if your system is using less than 75% RAM in normal working condition than there is no significant benefit by increasing RAM. But of course, faster RAM is always beneficial. So opt for the fastest RAM available in the market and increase RAM only if required for your working condition. You always need to check maximum amount of RAM and type of RAM that your motherboard can support. Also, it is limited by your windows License! Often you will come across various methods of using your HDD or USB as a RAM. I always had doubted whether it is reliable or not? To understand that we need to understand the significance of RAM in the system. RAM is designed to frequently read and write data during the process at a much higher speed compared to HDD/SSD (See table below). Also, a lifespan of HDD/SDD/USB will decrease significantly if used as a RAM. But you can use this function only a few times when you come across some work which requires extensive RAM than your normal work. For professionals, this feature may waste your significant time than saving your few bucks, if you are using more than 75% of RAM in normal working condition. Have a look at below comparison to get a clear idea regarding RAM.
CategorySpeed (Approx)Cost (Approx)
DDR3-1600 (10-10-10) RAMTransfer rate of 12.8GB/s (latency of 12.5 ns)$6/GB
SSD (eg. Samsung SM951)4.5GB/s read and 3GB/s write (Seek time ~0.08 ms)$1/GB
HDD 10000 RPMsequential media transfer – 1.6 GB/s sustained transfer rate up to 1 GB/s (Seek time ~0.2 ms & Rotational latency 4.17 ms)$0.04/GB
Some blogs recommend using tools to free RAM. As there is no method to access RAM directly to any software, software need to ask OS to provide more RAM. In that case, OS will write data to pagefile i.e. on HDD and then software free the space of RAM. In short, those tools are forcing OS to write RAM pages to the pagefile. So it is obvious that if your CAD software is using the most amount of RAM then all that data will be written to HDD and software performance will be drastically reduced. But it is useful if you run that tool before you start Inventor and perform a heavy process. It is advisable to increase RAM if you frequently need to do that. Pagefile : It is file/space located on the local drive which acts as a virtual RAM when all processes require more RAM than actual RAM. Page means 4KB pieces of information that OS move from RAM to the pagefile on the hard disk to free up some space on RAM for other processes. (#Instant) Don’t worry about this if you never use 75% of your RAM. If you use, then windows recommend making the page file 1.5 times the size of the installed RAM. But at any point of time, If you require more to work on the large file you can temporarily increase pagefile size. You can google how to set that based on your operating system. Graphics card : Never choose a graphic card based on review related to game performance. As it is an altogether different thing. CAD software demand for real-time rendering based on mathematical calculation while games demand renders which are predefined in most of the cases. Hence Graphic card manufacturer needs to provide appropriate driver along with hardware which is optimised for CAD performance. That is the reason you will find recommended graphic cards from CAD software. (#Instant) Sometimes I came across scenarios where cheap graphic cards which are not recommended by CAD software can decrease the performance and you will find improved performance when you disable that graphic card. So I personally suggest going for CAD software recommended graphic cards. Local or Network Storage (HDD / SSD) : If you are accessing big files from your local / network hard disk then only you need to consider this. (#Instant) Fragmentation is useful in case if you are using HDD. It will reduce head movement while reading. (#Instant) Always SSD (optionally Hybrid Drive) can give you better results but in case if you have budget constraints then, the Best practice is to use SSD for your OS and work folders (if you are using vault then you can configure vault to place the folder on that SSD). Purchase HDD for extra space, if you require putting your less important data and you don’t need that frequently such as Audio, Video files, Completed work files etc. Operating System : (#Instant) Advancement in Hardware and software opens the door for new functionalities for CAD software. No one can make an operating system support all future hardware. So we insist on using latest OS for new hardwares. On the contrary, never jumps into the new version and test that before you implement if you are doing work. If you are a student then you can jump to new system immediately. it will help you learn the latest technologies or functionalities. Network Environment (for Intranet and Internet) : It is very vast topic to cover here and it is mostly applicable to corporates. The whole network depends on a lot of factors such us the cost, security, no of the user, future plans etc. So I insist you consult good network administrator who can guide you in selection. (#Instant) In order to use the maximum amount of speed your network, you need every single component in your network (including your computers) to be gigabit compliant.
