How to make curved shells, offset tool? (by Rune)
Great program,
I need to create a shell (like a bracelet).
I draw a curve with lines, arcs or splines. How can I give it a thickness (i.e. create the two walls with a constant distance) before I extrude?
It seems like one has to manually trace the second wall and set a lot of constraints. Is there another way? (Like e.g. Sketchup you would use the offset tool.)

Any help is greatly appreciated

The best way to do that is to explicitly sketch the additional curves, as you say. You can generally cut, paste, and constrain, so it shouldn't be too much work.

SolveSpace works on NURBS curves, not just polygons like SketchUp. That permits us to export exact curves in STEP, DXF, PDF, SVG, etc. files, and improves mesh quality and the robustness of Booleans in some cases. It makes an offset operation more complex, though.
