stepped foundation

[dgavin]

OK< been doing kitchens and baths for too long. I need to step a foundation but cannot seem to
do it via a broken wall. The whole wall comes down. I just need to step the first 48" against an
existing foundation wall but it ain't working! Tried creating a room with an invisible wall to get it
to work but no dice. Can someone splain what I'm doing wrong? Ohhh LUUUUUUUCCCCYYY
