Usually, the easiest way to create an opening in a wall to place a portion of curtain wall is to draw the curtain wall in the same location as the solid wall. Then use the cut tool (available under the Modify Tab > Cut), select the curtain wall and then select the solid wall. The area that the curtain wall takes up will be cut away from the solid wall.

This way, if the curtain wall needs to be re-sized or re-positioned, the opening in the solid wall updates automatically.
