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.
