Project on a mesh

I want to project shapes vertically on meshes.
I would like to use Microstation (something like AutoCAD) but it does not seem to work for me.
The number of shapes is like a thousand and the meshes are about 100.000

Is it possible in Blender?

you mean project a texture on to a mesh, or project one mesh on to the other?

look up ShrinkWrap Modifier on youtube, that may be what you want.

100 000 is too much I think

you might have to split your file in several parts

also why do you want to project things ?

are the original file in 3 d or 2 D ?

can you export to another format like OBJ or Steps ?
