Hi
I saw your discussions on work arounds, and I will be trying it when I get the machine. Currently I use google sketchup 3D modelling program to do my design work which has a photo import and match routine. I do not know yet how it may work with carvewright, but
think it may work well. Below is a 2D image of a 3D graphic. The shadows created may have to be removed and textures adjusted to model the depth of cut desired.
The other great attribute is a vast online 3d warehouse of their models. see at
