I’m new to Grasshopper and Rhino and I decided to try using it through the ArchiCad Liveconnection to fix some Problem ArchiCad isn’t able to.
I want to divide Columns on a curve. I already fixed that Problem kind of but i want to set the columns orthogonal to the curve and i don’t know how to get the rotation angle i need to put in the Columns settings.
I thought I could fix that Problem through the Perp Frame function, but that doesn’t work.
Thank you Gursel.
I found out, that in the latest version of archicad (21), they added a command to divide objects and columns on splines and to turn it right to it. so archicad solved the problem itself
