When creating pavement using ArchiCAD Fills the Architerra help file says this
Note:
the nodes of the polyline are extremely important as they define the variations in altitude of the element. ArchiTerra uses these nodes to calculate the altitude of the element which will be placed on the ground with those coordinates (from the side selected as the reference side)
What does that mean? Does it infer that if the fill is a simple rectangle that covers an area which has alot of changes in elevation need to have more than 4 nodes? I'm having a little trouble understanding this instruction.
