Hello Dynamo Community!
I want to get the outline or points of a Column in a section view.
I need that to place tags, detail elements, elevation marks and maybe for dimensioning.
I don`t really know how to start, just a little first try:
Only thing i can get to work is getting the centroid point:
Would be happy about some advice 
THANKS!
Kind regards!
As the node error is explaining, it’s expecting a face as an input, but you’re giving it a solid. You could use the Topology.Faces to get the faces of the geometry, then feed that into your Face.Edges node.
There’s also a Topology.Edges node which will give you the unique edges of your overall geometry rather than the edges of each individual face, avoiding duplication if 2 faces share an edge. Depends what output you’re after.
