The claim that, in 1981, "Catia did 3D design, while all competitors were limited to 2D" is incorrect. Deltacam Systems, the division of the Delta Group that evolved into Delcam, demonstrated the first 3D CADCAM system at the Machine Tool Exhibition held in Olympia, London, during June 1972.


Agree with the last post. In 1981 there were many 3D design CAD software systems. These included McDonnell Douglas with UNIGRAPHICS, GE/CALMA, CV/ CADDS, Etc... Most of the automotive companies had their own internal systems, which were had full 3d surface capabilities just like the CAD companies previously mentioned.
