Subtracting 2 breps from each other !

Hey guys,

I am trying to subtract two breps from each other but i cant. i tried trim with brep and tried to use them as surfaces and use region difference, but still didnt work. I am trying to subtract circles from a surface basically! I feel like its easy to do, but i am missing something.

Attached is the definition. I used surface and orient only to orient the pattern to the elevation i want.

Hi Mahmoud,

you didn't include the 3dm file (or, alternatively, you didn't internalize the geometry in the GH file) so I cannot test that.

Tote that Region Difference is for flat 2D shapes only. If you want to subtract 3D shapes, you need Solid Difference.

wow thanks for the fast reply, i didn't know it would be that fast :)
any ways, here is the 3dm file. (so If i loft the circles in the orientation i want (creating 3d geometries) i could subtract them from the surface ?) because i am trying that now it does not seem to be working.
