Question on v-carve with 1/8" bit

The 3rd option would be to model in 3D and cut using 3D toolpaths in Carbide Create Pro.

Yes, you probably want to use a larger tool and “allow the program its head” and let it cut as deeply as it needs to.

Beyond that lie other tools, which save for Alibre, I can’t really speak to.
