Revolve + Curve

Hi forum!

I’m trying to revolve while also following along a curve, but I can’t quite figure it out.
What I’d like to do is revolve the green shape in a circle, while at the same time following the curvature of the red one.

Any ideas on how to solve this?
I’ve attached a file as well.

Are you talking about something like this? Sounds like you need to redraw what constitutes the “profile” that is being revolved, which would involve splitting it in the z axis. (again I don’t know if this is exactly your goal.)

Exactly like that, thank you sooo much Tom!! :smiley:

What commands, or what order of commands, did you use so I can replicate this process myself for some tweaking?

_split the green base curve in half using option Point and midpoint snap
_join both parts of the curve
_extrudeCrv the red curve to be big enough
_circle draw an circle - you still find it on layer “guide” in my file
_project the circle to the extruded surface

finally:
_railrevolve the final surface, the green curve is the profile, the projected circle the rail - use the scale height = yes option
