Array Families Along a Curve


Hi all, I’ve seen a few posts on this in the past but have not found any conclusive answers. What is the best way to array a rectangular family perpendicularly across a curve?

I have been able to divided the curve and establish coordinate systems that are perpendicular but FamilyInstance.ByPoint does not allow me to apply the orientation of the coordinates. Is this something I can dousing the UV grid? Can I rotate the
amilies after the array? An added rotation instance parameter is less than ideal.


Lighting fitting on a series of x,y,z coordinates

try creating a horizontal frame at parameters along the curve, then place families on those planes.


Not sure what you mean by “horizontal frame.”

Hi, I mean the Curve.HorizontalFrameAtParameter Node, you can just search for horizontal in the search bar
