Get point from intersection by line and mesh (topography)

Projecting buildings on topography (I have added files)

I’d say the easiest way to achieve this is using ray bounces, assuming that is a topography in Revit. The Data Shapes package has a node for this with a category filter, try it out. Get the min point of the bounding box of each building, then the ray bounced point and compare their Z values. You can then move each building by a Z vector of that size so it will sit at the topo level. Noting you will only be able to project them to one point of the building this way, so typically this would be ce…

Gavin Crump suggested using ray bounces in this case.
