Best CAD Software PTC Creo 2.0 or Solidworks or catia or inventor or solid edge or NX or autocad ????
Solidworks and Solid Edge, good, but expensive Geomagic, by far best value for an excellent product. These three all better than Inventor which is overpriced rubbish. The others I have not used so I can't rate them.
Taking price and value for money it's hard to beat Geomagic Design
Also Bricscad, abetter and cheaper product than Autocad
SolidWorks is the best CAD software in terms of features present. Can you let us know that what is the design requirement that you are having so that we can give you the details of how to make it easily.
