I use Geomagic Design from Alibre Design Expert. A lot of years ago, I bought the license Alibre Design Expert edition for Alibre CAM feature. Of course. When software was transfered to 3D Systems, I was using older version of Alibre Design Expert because it contains Alibre CAM. Several years later, I upgraded to Geomagic Design, and paid maintenances. Because I wanted STL import. So, I lost Alibre CAM feature. And, STL import is poor. It is working for only very very very simple models. Every free CAD has working STL import - Design Spark Mechanical included.
Finally - I pay maintenance every year. I have an active maintenance. I have an old Geomagic Design (latest version is from year 2015). I have no Alibre CAM. And, I have unusable STL import.
