Currently a straight wall cannot be aligned to a curved line of reference.
So in the instance where a wall was drawn straight, and doors and windows were added to it, when it needs to be modified to align with a curved gridline, for example, it will not have that option. So a new wall will need to be created and doors and windows will need to change hosts, and the original wall will need to be deleted.
This is time consuming. A solution would be to allow for a straight wall to be aligned with a curved reference line.
