Hey, Everyone, I have been digging through old topics for a while now and am still having a few issues dealing with rotating families to be perpendicular to a surface or curve.
Here is what I have so far.
For some, it is working, but it is a hit or miss.
Also here is my Dynamo file. (MY Revit file is simply a blank file created from the Arch template)
perpendicularFamilyPlacement.dyn (108.4 KB)
Thanks for the help!
