I see…challenge accepted.
There’s also one more way to make Dave’s way a little faster: Use a cylinder with a hole. By reducing the x-resolution of the cylinder you can also create rectangular or even triangular “rings” that can cut into a model.
Yes, you can still do it that way. I’ll make a 2nd video with more complex lines on the surfaces.
Btw: About that “round all” brush - what are the settings for this one aside from “smooth with grab dynamic radius”? That one looks really useful.
Thank you very much.
