I would like to hotlink some part of building (e.g. WC room walls in hospital) and multiple it many times, so if some changes in the module should be made, that would be easy.
But the problem is - the door opening ID's should be individual in All the building, regardless the doors are the same type or not. So their number in my project are driven by storey number combined with number manually written in Archicad Doors ID field. As far as I know it is impossible to change ID's of hotlinked element instances. So no hotlinks for me 😕
So the only drawback for this method as I can see is that all the objects within the module instance will get the same Master ID. For example If I have 3 doors, 2 sinks, etc., they all will have the same Master ID prefix before original ID
There should be two options: 'element ID' and 'hotlink and element ID'.
I typically use the 'hotlink and element ID' for things that require unique ID per placed module, for example zones. I typically use 'element ID' for things that should have the same ID regardless of being part of module or not, for example doors/windows.
