Some of my doors appear with different IDs even though I do not have Unique door IDs on.
This will only affect exterior doors that swing to the exterior side of a wall. All the pre-defined exterior doors
in SoftPlan are Pre-hung doors, defined to swing inside the house. Setting them otherwise would uncheck the product
code and change the ID letter. If an exterior door is defined to swing to the exterior it would generate the same
ID letter when swinging in that direction.
