Subtracting CW from a Wall

[MuazOnline]

Hi everybody,

am trying to subtract a CW (operator) from a Wall (Target) in vain ...

it shows me that the operations is OK, however on the 3D window everything is still in its place and no change is achieved !!!

Have you put the operator in a different layer (SEO layer) and turned that layer off?

[MuazOnline]

well actually i need to keep both of them
the normal wall
and the curtail wall
and all i need to do is to create a hole in the wall using the boundary of the curtain wall ...

Ok I misunderstood.
Instead of using SEOs you can put an "empty window" in the wall and put the CW in it.

You probably also want to give your "empty window" (that eduardo suggested) a unique name or letter to be able to exclude it from your window schedule.
