What are CAD Files?

CAD stands for “Computer Aided Design” and files with this format are used to store 2D (drawings) or 3D designs (models). Generated by CAD-based software, they can be used to create a number of things, including models, architectural plans, and more.

Today, there is a multitude of CAD file formats in use for storing high-definition, multi-dimensional designs of objects as every CAD vendor tends to create their own proprietary file formats.
