Before starting the demo for my review of CAD for Hobbyists I had never used PTC Creo Elements/Direct before. Years ago (about 10) I used PTC Pro/Engineer for a short while. PTC Creo Elements/Direct is a decedent of Pro/E. A few years ago Pro/E was renamed Wildfire, later to be again renamed Creo. The standard version of Creo is a parametric feature based modeling program. I had initially assumed that Creo Elements/Direct was a stripped down version of Creo, I was wrong.
