Extrude along rail questions

Hi. Probably a simple one - I have a profile curve I need to run along a rail, but I need it to stay 90 deg to the rail all the way. I can extrude, but it’s always parallel to the profile curve orientation!

Thanks!

Can you post a 3dm file?

You probably want Sweep1Rail and not Extrude.

Done, it worked but only when I selected the curve well away from the section.

Thanks!
