Hiya folks,
I was wondering if I could get the opions of the people currently
using some cad packages on the Macintosh.
We have noticed with much dismay, that many Macintosh CAD programs
have difficulties with their IGES translations, and with generating
"good" PostScript output, thus nullifying one of the Macintosh's
strengths. This was especially obvious when printing curves from CAD
programs. They seemed to rarely do a true conversion from the CAD
curve (e.g. b-spline, polynomial, etc.) into PostScript's bezier. The
result was unnecessaily jagged and thick curves.
We have found a product from ICE Engineering that converts CAD IGES
files into PostScript. A very useful utility, allowing CAD to be
merged effectively with Publishing. Due in January, this product looks
like a tool long needed on the Macintosh. Called IGES*PS.
We found ourselves sending the CAD output to IGES to run the IGES to
PostScript converter just to get good output on the LaserWriter.
Finally, most packages we have seen to date tend to be somewhat weak
on some of the more serious functions expected to be provided (like
multiple view capabilites, extensive curve sets, and obscure object
operators) but have noticed more of these as newer releases hit the
market.
