Twisting a bent bar

[Gijs (Gijs de Zwart)]

Is there a way to get the info about the rotation angle for a sweep 1 rail freeform?

I’m looking for a way to report back the total angle of twist of a 1-rail sweep that is set to freeform. See attached example. When I use roadlike and set it to top, then the profile is oriented to the XY plane the same at both ends. But if the profile gets swept freeform, the end profile is rotated. I want to know if I can get info on this angle in a script. Any ideas?angle_of_twist.3dm (234.7 KB)
