Rather than drawing curves in the command (Start of Cross Section Line, End of Cross Section Line), is it possible to use an existing 2D Curve?
This is so that I could update a history-enabled CSec with the existing 2D curve, which I’m using downstream for a Network Surface. The end Csecs then define where the ‘boundary’ of the Network Surface is.
Hello - CSec is always a plane defined by the two points picked and the perp to the construction plane. Do I understand that you want to use potentially non planar ‘paths’, i.e. any curve, not a line?
The input curve could certainly still be a planar line i.e. the normal input for CSec. But something that could be an existing line in the Rhino Document, and picked rather than drawn.
Then subsequently updated with History
I see - for now, though not very convenient, it is possible to set something up likes this with History and a little finagling.

Thank you so much for looking into this (and introducing me to the word finagling…)
Yeah I think you’ve got what I mean - attached a video just incase. Basically I can endlessly edit one way which is great, but not in the CSec direction. I get though that the good thing about the CSec input is that it’s kind of becomes an infinite line based on the points created.
