All as mentioned earlier, I work on Catia V5 for my daily duties (and I know there are others among us using CAD systems daily).
If you guys are interested, I will try to download each free software and assess it against my experience. Maybe this info will help others decide which one to use (from a RP perspective).
Suggestions as to which software to try first would be most welcome. I'm thinking of a separate thread where I can report outcomes?
I can judge them against the following and additional suggestions are welcome:
* Accuracy capability
* Point, line, plane and surface creation
* Simple solid creation
* Complex Shape creation
* Boolean Operations (seamless joining of separate solids)
* Filleting capability (turning hard corners into smooth ones)
* File type export capability (for RP)
* File Import capability
* Surface Quality
* Ease of Use (user friendliness, intuitiveness)
May take a while but I am willing to assess them if you guys feel it is a worthwile endeavour.
