I need help with the extrude along crv command.
Probably an easy fix but all the answers to similar questions don’t seem to be working. I need to extrude a cross section around a circular curve so that it is even all the way around. Currently the ‘extrude curve along curve’ command and ‘extrude surface along curve’ command extrudes the surface so that it is always facing one direction leading to tapered edges. Many thanks
Hi Freddie -
Pictures are of little use here. Post the 3dm file to get help with this.

I think you are looking for Sweep1Rail, not Extrude.
Hi,
Thank you, apologies the original file is too large but I have extracted the elements I need help with. I am trying to extrude the ends of both poly-surfaces along the curves. Many thanks

As I said, you could use Sweep1Rail, or, as the curves are arcs, you could also use Revolve around the arc center, which would give a cleaner result. Note however that your arc is not tangent to the rail at the junction…
