Objects snapping to curved wall behind flat wall

[LordBeowulf]

So I have a curved stairwell against a curving wall in the foyer with rooms having straight walls behind the curved wall.  I'm trying to add shelves and cabinets to the room behind, but any time I get close to the intersection with the curved wall, everything snaps to the radius, even if it's opposite the arc.  It also doesn't have to be cabinets.  It's any object.  Beds, furniture, etc.  How do I get HD to ignore the curved wall in the other room and lock things to the current wall.  Otherwise, how do I just lock the components from rotating?

 

 

Thanks,

 

Beo

Someone will need the plan file to experiment with.
