Here's the Amapi question? No integration or plugin connection to Carrara, just a standalone version, similar to what was on the Amapi 5.1 CD plus 5.15 applied to it, essentially. Mac and PC. The Carrara CD is a hybrid too. Amapi 5 exports to RDS 5, so that imports into Carrara's vertex modeler. Of course, if you use Nurbs in Amapi and want to pass it to Carrara, you should convert the Nurbs to polyhedral (double-click the part(s) ) prior to export to predict what polygons you end up getting. -Philip
