Hello @AndresKasekamp Hopefully I got your question right! In addition to @BrianWamsley All you have to do is draw another shape (the dimensions of your passage way) on top of the face using the shape creation tools. Make sure the shape is directly on the face. Hold "T" while drawing to achieve this. Hovering over the draw shape will bring a yellowish gizmo you can drag to the back and create that hole. Hope this helps. Doug.
