Empty fill after subtracting solid

Recommended Posts

You mean like the object at the top left?


If you were saying this was happening when you extrude an object I would say that the polygon you are extruding was not closed so there is no face to extrude, only the line.


But since you are Subtracting I don't know, but I would probably start by checking that all the original objects are closed.

Any chance there Has been a resolution to this issue? This is with a swept rectangle with a pitch. Might it have something to do with the fact that one needs to include a 2d locus point to make a helical sweep? or the compound curve it creates. 


Update: if I do a positive pitch and then mirror it, it appears to work. 🤔
