Rhino Grasshopper Projecting Objects to Surface

The topic of this tutorial will be the projection of any type of geometry onto a given surface which is not flat, but rather bent and curvy. With this Grasshopper script, we can find the lowest points of the geometry and project those points onto the surface. Then give the motion vector those distances in order to achieve the movement onto the curvy surface.

Comment by elizabeth carmody on April 1, 2020 at 10:58am: When I run this script to place buildings onto topography, each building is duplicated hundreds of times along the Z axis. Any idea why that might be? I've checked the script and confirmed everything is written correctly....Not sure why this keeps happening. The original geometry of the buildings are not duplicated in place or anything.
