How would I get dynamo to move square/rectangle shape surface to move to lowest point of topography?
Currently my graph creates array of points but is not accurate because the points may not be over the lowest part of topo. To get better accuracy means to create more points which will slow script down.
Aim is to get current revit family level and change parameter so it moves to lowest part of topography.
But I have several surfaces so what I really want is min Z-point of topo at each of these areas.
Is there a way to create topo bounding box the same x,y size of surface so it can work out the local min point?
Likely you have the wrong order for the surface inputs. The topo should be the surface input, the surfaces you want to move should be the inputs to project. And can you reupload the pictures with the outputs displayed? Just seeing the nodes doesn’t show us what the process is.
