Revolution of a shape that would intersect itself (without halving it)
The question is simple and I am quite certain someone has already pondered on it, but i do not know the correct keywords. I have a shape:
and I want to revolve it about the vertical axis. I cannot do that, because onshape complains as it only enables revolution of sketches that would not "self-intersect". I understand the complaint but I do not know what to do about it. This sketch is necessary to have for producing a dwg drawing with necessary quotas, period. I need to produce revolution from this shape and I do not want to make a second sketch that is just half of this one. I believe this to be a standard task and there certainly must be a trivial solution that i am missing. (Again, making a copy of the sketch and just keeping one half is not a solution that would satisfy me).

If you insist on keeping full sketch, just draw a line down the middle and select one half for the revolve. Since you're using the sketch in the drawing, the line will show of course. Personally I'd use @S1mon s approach then use a section view in the drawing.
