Can I import SketchUp models into Aspire/VCarve?

Yes you can.

Aspire can now load 3D models from Sketchup, in the exact same way you can from .STL files.

This is applicable for Aspire 4.514 and higher.

VCarve and Aspire can both now import 2D Vectors from Sketchup files.

This is applicable for both VCarve 7.514 and Aspire 4.514 and higher.
