I was hoping to "lose" only what was "hidden" behind the wall.
OK; I didn't understand the problem. You'll have to convert the text and dimensions to 3D objects. This is easy with the text; simply use "Flexible" Mode
and assign some small 3D Thickness
(via the Properties dialog). Dimensions are a little more complicated. Explode the dimensions one time, which will reduce each dimension to a Multiline Text object plus a collection of Lines and Polylines. Deselect the Multiline Text, leaving the Lines and Polylines selected, and open the Properties dialog to the Pen
page. Type a value (e.g., 0.05 inch) in the Width
field and specify "World" Scaling
; go to the Brush
page and specify "Solid"; go to the 3D page and assign a small 3D Thickness
; click OK to exit the dialog. Select the Multiline Text which used to be part of the dimensions and treat it as described above for text.
