CAD & file preparation

CAD (computer-aided design) allows engineers and designers to create 2D or 3D models of products before they are manufactured. CAD helps engineers visualize the part's construction and run simulations to test its parameters, such as strength or temperature resistance, before any physical models have been created. This results in a faster and cheaper workflow. These articles will help you understand how to use CAD modeling for your designs and how to correctly export your models for 3D printing.
