Like in the topic i have a group of smaller solids from a Civil 3D corridor. I transformed them into Dynamo Geometry and i need to extract the XY boundaries of them and then extrude the solid from those boundaries in Z direction. Unfortunately you cannot project the objects onto plane, so i tried to make a surface on the XY plane with Z=constant, but it is not that simple. Do you have any idea how to solve the problem?
My solids are on a real XYZ coordinates.
