Hmmm, let me see if I understand what you are doing since I don’t know CC Pro.
In design (not CAM) space you:
- Create (with math, say a cylinder section) or import (e.g., an STL) a “compnonent” that is the final stock shape. Here (screenshot #1) it looks like this is some kind of dome.
- You model the idealized inverse (protrusion, not sloped trench) of the Vcarve on a flat surface by extruding the closed contours of the artwork (letters here) up at a draft angle that corresponds to the bit you will be using (45 degrees = 90 degree V bit).
- You then subtract the height of the protrusion at each point above its flat base from the actual height of the curved surface below it at the same point (with some height offsetting).
I assume you would then in Toolpath/Manufacturing space use “normal” 3D tool paths to clear out the VCarve (like) trenches after first making the dome, using rest machining? Would you be able to actually use a 45 degree Vbit (i.e., zero radius) for these tool paths?
I think in fusion you can’t directly subtract (via combine) the height offset from a flat surface from the curved surface. But what I think you could do in principle is cut extrude with a draft angle the artwork projected to the curved surface. I think in principle this is the same thing, whether it works in practice … I’ll experiment!
(Thanks so much for the input. I’m super-impressed by the attention you give the community. It must get tiresome answering the same questions over and over.)
