I see Scott.
I have confirmed that it is only with V8 that some 3-d abilities kick in.
Upgrading will be up to the machine owner.
Back to original request from Ace:
What software are you using to create your 3-d curves? If you can create the base shape without the waves cut into it and import it, as for example an STL, then you can create the vectors for the waves and machine onto the model in Vcarve Pro 8.xx by projecting the toolpaths needed onto the imported model by checking the "project toolpath onto 3-d model box but not earlier versions.
