You can host profiles onto the nodes of a divided path (line), however they can't be conventional Revit profiles, they must be adaptive components - they can be quite simple drawn in 2d (XY axis) without even placing an adaptive point. When hosted on the nodes they will be automatically oriented perpendicular to the divided path. You can then "Repeat" them along the path - the number is then easy to control. The challenge is how to create and manage variations in the Repeater - it can be done but is not so easy.
