Thank you very much, Sam & Clement, for clearing this up. I’m not sure “about #4” either…they’re two separate commands. I was BTW able to simply split the scanned object (essentially a six sided organic (toy) top by using Clement’s suggestion recommending the _MeshSplit command. It works nicely, but I’ll need to fiddle with my XYZ=0 alignment of the object to enable my first and sixth mesh edges to come together properly. I’m wondering (having not tried yet) whether I should be rotating 300° rather than 360°, which probably accounts for the object not properly holding after command execution. If I, for example, rotate through 180°, the resulting object sticks.
The endgame here is employing a rotary 4th (indexing) axis to CNC this object on a router, using Vectric Aspire. I’d import the completed object, scissor split one edge, laying the unrolled, flattened mesh down for toolpathing, then re-rotating the object and paths for machining. I have a ways to go.
I generally work primarily in AlphaCAM, but only Rhino offers the CAD power necessary here. Thanks again!
