Hi,
i need to create a solid by extruding/offseting a spline surface (attached picture). The problem is, a solid created by simply extruding this surface "outside" would cross itself, so autocad does not allow me to do it (neither extruding, surface offsetting is working) I tried to make a cube then using this surface as a splitting spline - however a solid created this way is flat on z-axis. How can I do this ? Everything is fine with the spline as well as a surface - it's closed one. Obviously the problem is in the fact in the self intersection of the extruded solid. So maybe using it to split a solid is a better approach?
I would appreciate any help, i am sitting on this for almost 2 days now.
Thanks in advance
