Rebuild / Repair Curve

Is there a command to rebuild a curve and repair geometry?
As you see the curve creates no proper results during pipe command.

Same applies for imported curves from Illustrator that seem to work as I would delete some corner points for further use.

Maybe there is also another approach in repairing a curve. As sometimes the curve would work making a planar surface but sometimes not and the curve would properly lay on one construction plane and would be closed - but it work as a splitting curve for a planar surface.

So maybe there is some indicator tool to at least analyze the curve for the errors.

Thank you

I just completely redraw the curves with _InterpCrv.

Maybe you can also explain why the with the one curve the pipe would extent on both ends, even I redraw the curve.

Thank you

_FilletCorners with a small fillet on the original curves did the trick :slight_smile:
