How to project multiple Breps on surface

Hello!

I am trying to project multiple Breps (buildings) on a surface (slope). In the script I made the Brep moves to the lowest point where it intersects with the slope. It works when I set 1 Brep as the input but not when I set multiple Breps.

Can someone help me out! I have tried to graft and simplify here and there but it did not work yet.

Thanks.

Try this.

Thanks for helping, very clear script! But I would need not the closest point between curves but the furthest. Could you adjust the script?

Thanks for the help! As i understand the ‘box corners’ component is making a bounding box. Because the slope that i will eventually use it for is quite detailed i am afraid that the bounding box is not as precise as I want it too. It works good though! But do you think it could be a bit more accurate?

For even non-uniform surfaces.

The previous definition took into consideration only the edges while this one evaluates the entire base surface.

Different problem. Or is it

The difference between my two definitions.
