Why does my ring go twisted after Sweep1?

[Naomi_Yabar]

I’m trying to make a simple ring but when I sweep it, it seems to go twisted along one side. Does anyone know why this is happening?

Can you share the 3dm file?

My guess, the last line is in reverse.
Select the short lines and type dir. The arrows should match on all three (i.e. from centre out).

Select the flipped one → dir → flip.

Sweep1 works fine with that.
