I have problem to rotate an array group along x-axis. I created a ceiling array group and try to rotate the group along x-axis by using FamilyInstance.Set Rotation node. But, the warning error shows “No function called SetRotation on a Revit.Elements.Element that takes __array,int could be found”.
I understand this node is to rotate family instance around its local Z-axis. Can anyone show how to rotate array group along the x-axis?
