Failed Intersect

Rhino struggles finding the intersection of this pipe with the membrane.

Hi Thomas - I see that - Reparamterize > Automatic on the pipe sorts it out. Is that pipe exactly as it was made by the Pipe command? If so, can you please post or send me the curve?

It’s produced by chaining the edges of the red side-ribbon and then doing ExtendSrf on the pipe’s open ends
