Thanks for the tip. Pressing the 'Control' key while positioning the wall cabinet was new to me and perhaps that was why I couldn't get the wall cabinet to go beyond the face of the wall in my original attempt? I am creating an 'as built' plan of a 1930's house for a friend before we then do a renovation version of the plan. The part of the living room wall where this goes is opposite the original pantry in the kitchen and the pantry back wall did not extend all way to the living room wall. So there is room for the built-in after creating the wall opening for it.
