<p>wow! i really need this! Is there any way to get to to drop it "normal", assuming original is a flat object and you are dropping it to a curved surface and need it tilted to the normal direction of the surface?</p>

<p>In my case the "trees" are circles, so I can use Grasshopper to place tree blocks in the center of the circles, then I want to drop these 3D trees down to the terrain surface...</p>

<p>Just to avoid confusion, I dont want to project the 2D lines, that I can easily do within Rhino of course... </p>

<p>No not the drape function...</p>

<p>Imagine having a 3D terrain model, then you have a 2d model of the trees of that area in a single plane, then I would want to use this script to drop the trees down and they would "land" on the surface below...</p>

<p>Are you trying to simulate the Rhino Drape command?</p>
<p>You could simulate this with Kangaroo:</p>

<p>Use Project to find the 3D coordinates of the Point on the surface. If you need to orient the objects normal to the surface, you can evaluate the surface at the projected point.</p>
