Door/Window Instance identification

For doors and windows, this property identifies identical instances by a number (instance ID).
The program assigns a number increased by 1 to different instances of doors or windows.

The first door or window you place in a project defaults to a value of 1.
When creating a schedule, doors and windows can be grouped by instance value.

Location:
Building  > Door > Instance identification > Show

Building  > Window > Instance identification > Show

Instance IDs are assigned automatically and cannot be changed but it is allowed to add a prefix text. 

Location:

Building  > Properties > Openings > Door 

Building  > Properties > Openings > Window

Note: For projects created with programs prior to version 2021, the Rebuild 3D Model command automatically assigns the instance ID value to doors and windows.

Example: Door schedule using instance IDs.
