I’m pretty new to Rhino but am making wedding rings for my brother and don’t know how to “extrude surface” to make these letters that go all the way around the extrude negatively into the ring’s surface. My goals is to “engrave” these letter into the ring.
I did as much reading and research as I could and I believe I need to “Surface Extrude from Normals”?
At any rate, I don’t know how to do this from the center of the inside diameter of ring .
I believe the approach would be that I have all the curves of the letters grouped, and if I knew how to do the controls, I would extrude from the center of the ring so that all surfaces are pulled into the ring deeper to engrave the letters. At least .7mm.
Any one kind enough to tell how that is done?
