3DS release 4?
John:
If I remember correctly, there were a few reasons, but one of the big ones was
that they were trying to hold the 3.0 release name until AutoCAD went full 3D.
They then realized that Intergraph was telling people that they were only in
the 2nd major release of the program, and that ACAD was still too new to use.
So they went back and counted up the major releases, ended up with 9, and
that's what they called their next version! So now they are on the unlucky
13th version coming out in November. We'll see how their luck holds out.
