Just downloaded the latest version of AC3D - seems to be a significant improvement over version 4 ... which did not thrill me
Feaures which I like :
The texture mapper is much better
Extrude edges is nice
Still problems :
The boolean operations still don't seem to work well. Cutting a circular hole in a box using them results in approximately 6x the number of vertices and surfaces as compared to the create convex surface trick.
And new bug ??? :
Extruding a surface setting sections to a number >1 still results in only one section
