Hello, I am trying to create a graph that will array a revit family along a curve and rotate it so that the element is always facing towards the centre point of the curve. So far I have created tangents along the line at the insertion points and rotated the elements by the degree between the tange…

Hope this one helps [image] Copy family instance to follow a curve Geometry Looks good, I can’t really work out the problem from the image you posted. might be worth trying to use “CurveTangentAtParameter”, like this example. [image]

I forgot to say the problem, it places it along the curve but it does not always rotate the familys properly.
