The earliest application of CAD was in automobile manufacturing. in the aerospace and electronics industry production of large companies.

Later, with the evolution of CAD implementation technology and the change of computer technology, its application range has gradually become wider, and it is now widely used in many fields such as graphic printing and publishing. Wild reeds.

CAD (ComputeraidedDesign) was born in the 60s and is a Massachusetts Institute of Technology in the United States.

A research program in interactive graphics was proposed, which was only available to General Motors in the United States due to the high cost of hardware facilities at that time.

and American Boeing.

Summary. Hello dear dear, I'm honored to answer for you. There are many different versions of CAD.

Different versions of the production cannot be opened to each other. In this case, we can use third-party image viewing software. It is more recommended to look at the drawings of Swift CAD.

This one I've been using all the time is very good.
