Door and window number need to differ between otherwise identical module instances

Paul King — Thu, 21 May 2026 12:36:02 GMT

I have a project where two adjacent multistory buildings are almost identical, that would make perfect sense as two placed instances of the same module, but that need door and window numbers that are unique to each building.

The building design will continue evolving, and it makes little sense to keep updating two separate buildings.

How can I get the door and window markers within modules to automatically display a different door or window number prefix depending on which placed module instance is involved in plans, elevations and schedules?

A further complication is they (crazily) occupy different constriction and documentation phases, so need to switch on or off accordingly in views, depending on which phase I am showing. I am using design options as the nearest thing ArchiCAD seems to have to phasing control that does not require massive duplication of layers.

Operating system used: Windows

Do you use module id for something else?

Here is how to set the Master ID of the Hotlinked Module and the ID of Doors/Windows in the source file of the Hotlinked Module.

Thanks Laszlo - that got me quite excited for a moment, until I found that this option seems to be missing in CI Tools door and window markers (whole project uses CI Tools doors and windows)
