I have been using Rhino.Inside Revit to place columns along a curve. I have the normals at the point of placement, which i was going to use to rotate the columns, however they all place according to world xyz. I tried rotating all the plane, then using the new rotated plane as a host, i tried rotating the geometry afterwards in grasshopper, which gave null results. I tried hosting the columns to a curve, and rotating the curve.
I could create a rotation parameter within the family itself, and then map the angle to that parameter. I feel like there must be some simple thing I’m missing.
thanks in advance,
