On the subject or class A surfaces, Pro/E can class A just like the others. I have used CATIA 4 and 5 and UG and have determined that Pro/E does not lack in surfacing. You can make curves tangent, make continues curvatures, make surfaces tangent, be influenced by neighboring surfaces. I have been on CATIA V4 for sense 1985 and Pro/E sense 1997. When I started my business, I looked at all the major CAD software and I noted that Pro/E outperformed everyone else using a PC. I have determined that PRO/E is my system of choice base off easy of use and realiability. I have employees that mentally can manage parametrics but can model using lines and circle and surfaces ex. CATIA V4. It takes them longer but it can be done. They don't have the mental capacity to understand Pro/E. CATIA V5, sense I have been force to lease one seat and use it, I have determined that the reason Dessault Systemes purchased Solidworks, which we all know the original programmers were from PTC, is CATIA V5 is way underdeveloped. Notice how many releases of CATIA V5. It's a sure sign that CATIA V5 has to many improvements to parametrically compete with PTC. PRO/E is where it's at. Texaspete.
