Trim Brep

Hello everybody!

I would like to share my problem with you guys!

I have a wall and i would like to open two doors in it. 

The wall is an open brep while the doors are closed brep.

I tried to use also SolidDifference but the result is not a wall with two openings but the openings with half section (the wall is cutting the section of the doors).

Could you help me please?

Thanks a lot to everybody!!!
