Lets start with a tangible explanation of Computer Aided Design

Above is a picture with a CAD model on screen being developed by our CAD designer. 

Below is that same 3d file but you on your screen





Computer-aided design , or CAD, is the use of computers to create, analyse, modify or optimise a design. Its a 3d digital file which can be emailed to any CAM manufacturers anywhere for instant fabrication.

Its the 3D blueprints which you use in all parts of the product development process. In the beginning stages you draw a CAD model to visualise its form, then testing its used to upload to a 3d printer to prototype. After a back and forth of amendments to the CAD file from one prototype to the next this tool is used constantly. In the later stages the CAD file is used to make 3d art work for marketing, its the file you send to a manufacturers to receive quotes, it can a file you use to communicate building works to a contractor. You see where I’m going with this, making almost any product these days requires a CAD file at literally every step of the way for hundreds of different reasons 

3d cad files can be used for product visuals, CAD/CAM models for rapid prototyping, models to analyse force simulations to name a few.


CAD is mainly used for detailed engineering of 3D models or 2D drawings of physical designs. A CAD file is a blueprint

design file which drives computer controlled machines (like a 3D printer or injection mold press). A typical CAD file will include

2 vital elements. One, a 3d shape of your object accurate to a fraction of mm, in the 3d software you can preview the design in the 3d environment, rotate it, zoom in, view cross sectional and so on.

Secondly it will have exact measurements of the design.
