How can I exclude Geometry from Subtractive?
is that possible ?
and if so how?

Geometry BSP brushes have an order, which is why a subtractive brush will not subtract from an additive brush placed after it.

The solution: **Click on the Brush you want to exclude, go to Brush Settings, hit Show Advanced, click “Order”, and select “To Last.” This will re-order that brush so it isn’t subtracted by any brush.

Hope this helps!
