Issue Description
What is the Hotlink ID and which file/element holds this data?
Solution
In Archicad, the Hotlink Master ID is a property of the hotlink on the plan (in the host file), not of the linked file itself.
When you place a hotlink (like a module or external reference) into your host project, the Hotlink Master ID is used to identify and manage the hotlinked element within the context of the host file. This ID helps with organizing and differentiating multiple instances of hotlinks, especially when there are many linked modules or external files in a project.
The linked file itself (the module or external model) doesn't inherently carry a "Hotlink Master ID"; it's more of a reference or management tool within the host file to keep track of which instance is where and how it relates to other parts of the project.
