Hi I am new to civil3d dynamo. Wonder is it possible to find the center point of this manhole? Becoz the insertion point is not in the center. I want to use dynamo to move this manhole

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