Design approach pile component for piling box
I am trying to resemble the Revit example for a piling box as below
I have taken a U-profile and parametrized from a vendor catalogue and added a design table as follows
My nooby idea is to draw a rectangle polyline and project the component along and then to adjust either U-profil component and/or rectangle size in order to arrive at proper corner overlaps.
What would be a flexible approach to this matter?
