Subtract an imported mesh?

[SirKlu]

How i can subtract with the brush an imported mesh for a 3D Software. This is exactly what i want, i've created a modular walls etc and i don't want to create a modular wall with windows to each type of wall, there's anyway than i can substrack with the brush an imported mesh? It's even possible? Thanks you

You can only subtract brushes -> it doesnt work with meshes

Then i need to make modular windows for each type of wall? D:

Yep, you have to do that in your 3d program
