Mike;
PTC just don't have a clue about the needs of their extant users. I agree - why on earth would they be wasting their time on features that in most cases are of little use to engineers. Mathcad is an engineering tool and is therefore of no use to most Creo drafters. From my experience most drafters don't have the necessary background in math to be able to use such a tool. AutoCad has a built in calculator and this is all most drafters need or want. If Mathcad Prime 4.0 dosen't deliver our engineering needs then all should withold maintenance until they do. Or may the PTC management are big fans of Dire Straits "Get your money for nothin' get your chicks for free" . All I can say is that if Mathcad Prime 4 doesn't deliver on its promises then PTC is indeed in "dire straits".
