_ExtrudeSubD supports adding extrusion thickness along the curve
ExtrudeSubD.3dm (204.5 KB)
Hi @xkdsofa ,
I’ve filed this request as https://mcneel.myjetbrains.com/youtrack/issue/RH-81652 for future reference.
This is, as you may know, possible now with a combination of DupEdge > SubDSweep1 and ArrayCrv. I agree though that it would be easier with an AlongCrv option in ExtrudeSubD.
