Re: Renumbering Door Tags
The door mark (or number) is a property of the door. So purging/reloading the tag isn't going to do anything. Doors are numbered in the order that they are placed, but counting continues even if you delete a door.
For example you place doors 1 and 2, and then decide to delete door 2. Then you place another door...it will be number 3.
The best place to renumber doors is in a schedule, where you can sort the doors by "room to/from" number, and then you can work your way down the list renumbering them.
There is also a door renumbering tool by Avatech available on their webiste.
