Hi everyone!
I’m trying to do something similar posted here http://dynamobim.org/forums/topic/flow-along-surface/ . In my case I want to unroll de section lines between a spiral stair and a cylinder… but I can’t realize it… the stairs are made by several flights no continuos (1cm gap) because is a precast stair. So I got about 20 surfaces as result to intersect the cylinder with stairs, so I’m trying to unroll the edges to get a circular unfold section projecting the curves on a planar surface (wich is the cylinder 2.855m radius unfold). Hhere the .dyn https://drive.google.com/file/d/0B0l8DNpUDrjIM0hkRnpYV3RQQnc/view?usp=sharing. Also some captures
Thanks!
