I actually recreated the sketch from scratch over yours.Ondra.Holicky wrote: ↑Wed Sep 18, 2019 6:19 pm I can see now, which wires were useless, so those you removed, were probably problematic?
Each edge must connect to two other edges. Each vertex should belong only to two edges. Edges should not intersect - sometime this might work but the result is not well defined and will probably create problems.
This is only for the real geometry. You can draw construction geometry as crazy as you want
