I think I've found the good parameter : double wall - Frame Through OR double wall - Furred Wall.
When I use furred wall for my interior wall, it's OK : I can move the interior wall without moving or deleting exterior wall
If my interior wall is set to frame through, when I move it, it change the position of the exterior wall or delete it.
Is there an option to add an insulation layer wall automatically when I draw the exterior wall (CMU blocks stem wall) ?
