Select which topography to host the building pads creation in Dynamo

how to Select which topography to host the building pads creation in Dynamo?

I see some OOTB nodes and packages that create building pads by curves, building pad type, and level or height offset, but how can I choose the topography?

I got 2 same topography elements in same place, I create the pad and it cuts the topography that I do not want, I want to choose to intersect with the other topography, but Revit chooses the latest topography created, same with splitting or subdividing topographies in Revit.

what do you mean creating the pad in other topography?

I got 2 same topography elements in same place, I create the pad and it cuts the topography that I do not want, I want to choose to intersect with the other topography

like this?


That tells you which is the host of every element, but how can I change the host of a building pad or choose it before creating it?

Can you show your graph? where are you struggling?

I do not have any graph, Revit creates a building pad over other different topography that I do not want, and I am looking if it is possible to fix with Dynamo but no idea
