Daniel you talk abot slopy techniques, however in sheet metal you can model things that overlap when unfolded and Pro-E lets you get away with it. I will always remember a Solid Edge induction day, where I brought in a sample from Pro-E to see if it would load it up and Solid Edge instantly flaged up the problems. Solid Edge does not let you do silly things like that.
Solid Edge has actually killed off Pro-E and got PTC running like a headless chicken to catch up with the superior non history dependent modelling system. The syncronous tech is a ground breaking game changer. That is why it is market leader....It is designed by actual engineers ,for engineers and not by software programmers with what they think is a great idea at the time.
