I have an irregular curtain wall in Revit. It has angled edges. I am pulling the non-rectangular edge panels into Dynamo, tracing them and using the corner points to place adaptive components. When I create the polycurves from the panels, I get a list that has some with 4 points, and some with 6 points (highlighted in the image). I want to take all of the 6-point ones and turn them into 4-point ones. They are all 4-point polygons, just ended up with some extra points along some edges. Any suggestions on how to remove the extraneous points?
