I have searched the forum a bit but since I already have a hard time trying to synthetize my question I couldn’t find any answer.
Hope I won’t bother anyone with this.
Anyway, to make it as simple as I can, I’m trying to model a handrail for a strange shaped starway (not a simple rectangle/cylinder thing) with a complex detail (not a simple circle/rectangle section). (ill.1)
The sweep command is great, but it rotates the section according to the shape geometry, and I would like the section shape to remain as it should (ill. 2), meaning with the curved part on top of the handrail, and the flat part at the bottom (ill.3 showing the problem).
Thanks for your reply, unfortunately, for some reason this option is not available. I have tried setting a serie of cpplane in GH along the curve, but I didn’t manage tto do naything more than perpendicular cplanes at specific points and even so, from then I don’t know what to do…
I think the problem is the direction of handrail of yours can`t match the curve Pframe directions.
You can evaluate the curve with 10 Pframes(the more evaluated Pframe pts, the smoother shape you get), and then align these Pframes to the directions you want. Finally you get 10 geometries with right directions and go Loft.
Thanks for your reply.
I already have tried that, but the path shape is rather complex and the number of planes to set is long… I was looking for someone to point me to a turnaround with GH to automatize this…
