Move Geometry on Topograpgy ( Surface)

Hello everyone,
I have this problem, I have an urban division distributed over a 2D surface (Photo Distribution file attached) and I would like to move it to the actual topography (photo Topography attached file), can anyone help me?

Is project Curve onto a BREP what you are looking for?

thanks for the answer, but that’s not what I mean, I have a series of surveyors (buildings) built on an XY plane, and I want to project them on a 3d surface (topography), the geometry I have like the one in the picture (buildings) must follow the forms of topography.

Extract a base point of the building. Project it in z-direction onto the surface. Move building from base point to projected point. Btw still nothing attached.

Great! Very useful, thanks for sharing this.
It helped in placing trees on a terrain controlling the height above the ground.
