Hello, I was using the InterpCrvonSrf to create a facade on this solid, now I’m trying to figure out how to extrude them along their respective orientation/axes. For eg, the one facing front will extrude forward, and the one facing east will extrude along that direction as well. Thank you in advance 
Fin command:
The Fin command extrudes a curve on a surface in the surface normal direction or tangent to the surface. Rhinoceros Help - Fin | Rhino 3-D modeling (mcneel.com)
(If this is what you need please check “solved” so others not this has been solved.)
Hello! Thank you for the tips on the command, I’ve tried it. However, the Fin command allows the curve on the fillet edges to spread. Is there another command or tips that I can use to prevent this? Thank you!
What do you want to result from the curve on the fillet portion of the surface? If you don’t want it to be extruded then split the curve before using Fin. Of do you want something else?
I was thinking if there is a way to extrude the curve altogether (the fin allows to extrude curve per srf). Maybe that way I can avoid the spreading on the curve surface.
ExtrudeCrv can extrude a curve in any direction. ExtrudeCrv the curve in both desired directions, then trim and join the results as desired.
I got it! Thank you so much
