Why Is 2D Cad Drafting Still Important In The World Of 3D Modeling In All Architecture Sectors?

Previously, engineers used to use old-school pencils and paper for drawing.

The invention of cad drafting services has transformed how machine creation works now.

Currently, 2D CAD drafting and 3D CAD drafting are the most popular methods of creating machine designs and planning.

Anyone’s intuition would say that 3D is the superior way of CAD drafting.

But it will surprise you that many engineers are still using 2D CAD drafting today.

To know why, you have to first understand the difference between 2D and 3D CAD drafting services.

Difference Between 2D And 3D Cad Drafting

1: Features

Just like the name suggests, 2D CAD drafting offers designing in only two dimensions, which are length and height. There is no depth.

3D CAD drafting offers design in three dimensions, which are length, height, and depth.

The measurement unit is also different for both of them. 2D drawings are measured in cm2 while 3D ones are measured in cm3

2: Design components

3D CAD design allows you to design the exact shape and structure of your building.

2D CAD drafting relies on geometric elements such as points, lines, circles, and various other shapes.

3: Presentation

Because 3D CADs are exact replicas of your concept, it is easy to present them to others.

Even a layman can understand the design.

But, 2D CADs are flat. This makes it difficult for people to understand.

Only people from technical backgrounds would be able to convert the 2D design to 3D in their minds and understand how it would look in the real world.

4: Making changes

When it comes to machine design, making changes is quite frequent.

When it comes to 3D CAD drafting, making changes is super easy.

It is possible to make changes with just a few clicks.

2D CAD drafting is way more complicated.

First of all, finding the error is a big task. Then fixing it is another level of difficulty.

5: Prospecting clients

As 3D CAD is a photorealistic representation of the concept, it is easier to present to a client.

Most clients will not be able to understand 2D CADs and will end up rejecting your proposal.

All of these points just show how advanced 3D CAD drafting is.

Yet, you would be surprised to know that most people still use 2D CAD drafting services.

There are certain benefits offered by 2D CAD drafting services which are irreplicable by any other software.

5 Advantages Of 2D CAD Drafting

Although it is a last-generation technology, 2D CAD drafting still has some advantages over 3D CAD drafting.

Many professionals prefer to use 2D CAD drafting services for conceptual drafting and to study minor details.

1: Ease of use

2D CAD drafting services are super easy to use and work with almost all computers.

They are less demanding and run on older computers as well. Comparatively, 3D CAD drafting services require higher-end computers to run.

The file size of 2D CAD is quite small and easy to share.

Also, 3D CAD drafting services require a higher level of expertise. It offers many functions that can be overwhelming for beginners.

2D CAD drafting services only contain the essential features, making them much more beginner-friendly.

2: Easy collaboration

If multiple professionals want to work together on a project, 2D CAD offers easy sharing.

As the file size is reduced, uploading and downloading projects becomes effortless.

When integrated with the cloud, multiple people can access the project and work on it.

3: Time efficient

2D CAD drafting services automate many things for users.

It calculates the changes made automatically and also learns from previously built designs.

This minimizes many things and allows the user to focus on other important areas.

As collaboration is easy, any error in the design can be fixed immediately.

This saves a lot of time.

4: Usability

3D CADs require a computer to be viewed. But not every production center will have a computer next to it for workers to see.

2D CADs, on the other hand, can be easily printed and shared with everyone.

5: Economical

As 3D CAD drafting services are much more advanced, they are very expensive as well.

When you hire a designer to draft a 3D CAD, the cost goes up as the process is very time-consuming.

On the other hand, 2D CAD can be made in a much shorter time. So, the hiring cost of the designer goes down significantly.

With the CAD ready, you can begin working as soon as possible.

This is the biggest reason why professionals still prefer 2D CAD even today.


2D CAD drafting offers numerous benefits that make it the preferred choice of many professionals, even when 3D CAD drafting is booming.

Cost efficiency and less system-demanding software are the major reasons why 2D CAD drafting is still being used today.
