We used PTC Creo 3.0 last year for FTC for robot design in our summer camp. In the fall the students used Solidworks to design parts for 3D printing. This summer camp we want to focus on 3D modeling for printing. Watched some older tutorials on PTC Creo Elements/Direct Modeling Express 6.0 and looks impressive. Separate download and free. Wanted to understand if their is an equivalent software tool in the download of PTC Creo and how does it compare to Direct Modeling Express 6.0
