RT Booleans

Architron (LWCAD) is using two types of Boolean operations:

Non-destructive Booleans (parametric object modifier)

Non destructive boolean operations are implemented as part of the parametric objects.
You can enable a non-destructive Boolean operation when it is attached to another parametric object or LWCAD object. 

When booleans are enabled, the child becomes a parent modifier and the parent is modified. After freezing this hierarchy, the modifier (children) is removed and the parent (modified) has the resulting geometry.

Cinema polygonal objects must be converted to LWCAD objects before Boolean modifiers can be applied to them.

Non-destructive Booleans offers the following modes:

Reduce:     Automatic reduction of polygons after a Boolean operation.

Destructive Booleans (polygons)

Polygonal boolean operations are implemented in all Cut Tools.
Works when applied to selected polygonal objects or LWCAD objects.

Non-destructive Booleans offers the following modes:
