Sims walking through door part of open door and walls

When leaving or entering a room, door opens but sim walks through the door part and not open space part.  Tried on both a lot with move objects on used and without.  Tried pointing door both ways.  Removed door and put open arch and Sim walked through wall next to it.  Tried in both small and larger room.  Tried in old and new save.  Also pets (only play with cats so they are small) are walking through objects even other sims.
