When I am creating a model( floor plan) I sometimes have to align my interior wall with the exterior one. But the exterior wall is created with the snapping line on the outside of the building. Therefore I need to align manually, to be as close as possible to the inner line of the exterior wall.
This is an issue because:
1. Zooming in and sometimes out creates gaps.
2. Unprofessional look when not aligned properly.
3. Ease of use, as I would not waste time on "close enough" fidgeting with the inner walls to be as close as possible to the outer wall.
