Why You Should Use CAD for Drafting

Before we discuss why CAD is important for drafting we need to know what actually is CAD-drafting.


CAD drafting is the use of Computer Aided Design software and hardware for drafting purposes.

Do you ever wonder how engineers develop cars, airplanes, roads and buildings with such precision? Well, even though they are intelligent in this art; they effectively get help from Computer-Aided Design (CAD) and use these tools for drafting applications.

CAD is the technology used to automate the drafting process. Computer-Aided Design is essential for engineers and architects since it helps them improve design quality reduce measurement errors as well as saving them time.

Most architects and engineers, as well as those of CAD FM, use general-purpose CAD software for drafting. In contrast, some use very particular types of CAD to help them draft construction documentation, explore design ideas, use photorealistic rendering to get a real time impression, and simulate the processes and structures.

10 Reasons Why You Should Use CAD for Drafting

Here are 10 major reasons why you should adopt CAD for drafting in order to escape your industrial dinosauric demise. See the analogy below:

Reason #01 CAD improves the drafting design quality

Among the vital importance of CAD is that it improves design quality. To many engineers of the younger persuasion, it may seem a myth to draw out plans by hand, but in the recent past, engineers in teams would spend weeks drawing out plans for a simple design.

When designing manually, designers are at risk of human error but with CAD software, engineers, including our designers here at CAD FM, can design with perfect accuracy and precision – everything is pixel controlled.

Reason #02 CAD is cheaper drafting tool for complex and mega projects

CAD is better, easier and less expensive, especially as projects become larger and more complex, as compared to manual drafting options. Here at CAD FM, we draft designs using CAD, making them more attractive to investors; thus, the product becomes more sellable.

Reason #03 A layman can use CAD for drafting

In the manual drafting, you almost needed to be a calligrapher to be a draftsman, but with CAD, novice designers can compete with others on a level playing field.

Reason #04 CAD reduces communication errors whilst drafting as a team

Since collaboration is an integral part of a drafting process, designers and engineers work with other experts and simulate actual performance by sharing information with engineering and manufacturing teams for feedbacks and feasibility studies. CAD has increased that speed and reduced the communication time.

For example, auto manufacturers, through streamlining the development process, can reduce the time used from drawing board to the assembly line.

Reason #05 CAD drafting can directly be used as an input for simulations

CAD drafting can directly be used to create 3D models and these 3D models are a direct input for computer simulations. The real-life situations like high speed motion, the violent impact caused by accidents, harsh weather, wear and tear can be manipulated using these computer simulations and that can help identify and eliminate design faults.

Reason #06 CAD drafting can quickly be changed and updated

The designs drafted in CAD systems can adopt changes faster compared to the conventional drafting methods; thanks to the easy use of CAD file formats. You can easily open a design on your computer and modify it without any problem.

In contrast, if you need to make any change on manually drafted design, you may have to make a complete design from scratch.

Reason #07 CAD drafting is an easy tool to bridge generation gap

It is well known in the manufacturing and civil engineering industries that the senior experts do not like any change in their processes. One of these major changes is the use of advanced CAD systems such as 3D printing which uses 3D models.

The old school but experienced engineers do not like to switch from their manual methods to automated ones.

CAD drafting is a perfect fit for such situations where you can use sequential persuasion to move these people from manual to CAD drafting and then from CAD drafting to advance 3D modelling and printing systems.

Reason #08 CAD drafting are aesthetically pleasing compared to the manual ones

In manual drafting lines can be of different thicknesses and very random sometimes. CAD has uniform thickness and angles because the lines follow the exact pixels. Moreover, different colors can be assigned to represent different sections with better accuracy and precision.

Reason #09 Writing notes is difficult and time consuming

In manual drafting, stencils are usually used to write notes and statements. Whereas, in CAD, different fonts and text sizes can be used to make notes in no time. Writing any type of text is very easy and simple with CAD systems. You can control the text dimensions, orientation and shapes with a click of a mouse button.

Reason #10 Different view types can be created

CAD drawings usually require different types of views such as zoomed, auxiliary, cross-section and detailed views to convey information about the design idea. Most often, the important information was missed by manual drafters as they had to use their own imagination to transform the complete idea.

However, in CAD drafting, all the information is stored for a design and the above mentioned types of views are represented without any error on the drawing.

Also, it took days to completely represent such views compared to button-click in case of CAD drafting.


It is beyond a shadow of a doubt that the companies should adopt CAD systems for drafting in order to make a significant impact and lead the competitors. If the companies will not adopt CAD systems for drafting, they will become extinct like “dinosaurs”.
