Important Parameters:

• Side: From which side is the recess calculated. You can also think of this as which normal to use.
   
• Cut Out:  Cuts a hole straight through to the other side.
• Distance from front: How far in shall the recess start. A 0 value means from the surface.
• Countersinking: How deep is the recess
• Height: Enter a manual value or choose one on screen (as shown in below example).
   
• Dimension type: How shall the recess be dimensioned on a shop drawing.
• Annotation: Text used in shop drawing to describe recess.
   
• Material:  If the recess is to be filled with a material, ex.a different mixture of concrete, insulation etc, specify it here. The recess will then be accounted for as a filling.

If you choose 'specify the height on screen', select a base point and then the second point. Use points on the surface (in this case front) that you specified in the dialogue.
