I'm trying to do a sort of swept cut that tapers off and disappears. I thought I had it with this boundary cut, but it keeps giving me this error.
I am not sure what you are trying do accomplish here. Is it this?
Yes that is it exactly. How did you manage to do that?
I made the sketch on the front plane (i think) and extrude cut with offset from surface 0,03 (offset from inner face of model) as i remember.
Your issue is not clear enough.
..well your profile is not aligned/constrained (should also be a bit bigger (not a sliver) and although boundary cut does work like a sweep cut.. I'd choose a sweep cut.. and/or use a 3DSketch onto the surface for the cutting path (image)..
That looks great thanks. I was able to replicate it (I think) using spline on surface. That was a helpful tool--I didn't know it existed.
Is that what you used for the "3D sketch on surface?"
Since your sidewall is already tapered, why not just offset your front plane and use your path/guide sketch to do a normal extruded cut?
