Center point of manhole

[JPhil]

Looks like one way would be to extract a solid from the structure then use some geometry nodes to get a coordinate.

This post might provide some guidance…

Create Points from Top Center of 3D Solid

Is there a way to obtain x,y,z values from only the center point of the top of a 3d solid? I see the Solid.Centroid, but want the top and not the middle of the geometry. I have a ton of 3D Solids in my drawing. Any help would be greatly appreciated! Thanks Steve Walz
