Hi,
I am trying to find out to describe an objects edge. But this edge should be visible on the plan and has to be on the outer border.
In the picture you see 4 edges of a foundation with yellow. All I need to describe one of these edges in dynamo.
Why do I want it? To start the leader point there.
Thank you all in advance.(I have already figured the elbow point and header point, but the start point I cannot define)
