I never used multi-category tags, but read how they can be used and created. But I'm stuck with how to select the parameters needed.
The problem I'm trying to solve:
- I have a space tag that shows the space name, number, area and lighting power density
- I have a generic model tag that shows the illuminance calculated by elum tools. elum tools stores the data in a generic model family and i have its visibility enabled for reference (the bluish thing).
- the issue i have is i have to place both individually and align them so they look like one label.
i attached both tags.
i started a multi-category tag and created a label. but I'm already running into the problem that i can't select the parameters i need. it seems I could create shared parameters, but the ones I need (lighting level, lighting power density etc etc. ) are not shared parameters
and once I create the label, I'm also not sure how to place it so it picks the space AND the correct generic model element.
I wonder:
- is what I try to do even possible within what Revit provides? Maybe I mis-understand what multi-category tags actually do.
- If it is possible, how do I do it?

Huh? "Elum tools stores the data in a generic model family"? So, elum tools is creating a Parameter Field for that data in the Family? If so, can't you export that Parameter to the Shared Parameter Text file and use it in other Tags/Project Parameters?
The Generic model element that is placed looks like in the 3D view below. I think making those parameters shared is possible. I attached their family for reference. Actually pretty neat how they do it and that also stores the point-by-point calculation results.
Assuming I can solve the elum family parameter, how do I get the space parameters? they are hardcoded (space name, number, area and Lighting Power density w/ft²)
I don't see any lighting level or lighting power density parameters in this Family. Aren't those the two that you need?
Regarding your other question, I was thinking Shared Parameters to Project Parameters to Spaces Category. That would get the Parameters in the Space Properties. From there, I don't know what's next. I'm just thinking aloud. I'd have to know what I need to solve for at that point.
It's the one circled in red. Before you asked, I never looked into detail since I'm not messing with their family.
In the past I had extracted some of the elum parameters and made them shared. For example a yes/no parameter that declares a fixture to be an emergency light (and to what dimming level) for the emergency lighting calcs elum does. so my fixtures have an instance parameter that declares them to be an emergency fixture. On the view that will add a big black dot, and it also will activate it being emergency fixtures in elum tool plugin. Actually neat how it let's us play with it.
I think the only way the space parameters could work if I create similar shared parameters, and then have some equation to ensure they are the same value as the hard-coded parameters. the original hard-coded parameters have to play a role somewhat since they automatically populate (space lighting power density is based on actual fixtures in the space)
Edit: I made that elum parameter shared and included it in the multi-category tag label. It works and shows me the same 33fc as the standalone tag. So this part (hopefully) is solved. But I don't have an idea how to include the hard-coded space parameters. If I create similar shared parameters, and based on those create project parameters, I'm still left to how or where to enter the equation "this shared parameter = that hard coded parameter". The project parameter editor doesn't seem to have such feature.
Instead of placing the space tag AND the generic model tag (and aligning them to make it look like one tag), I would just place a single tag.
And I would learn more about multi-category tags and parameters while figuring this out..... But this is always a positive side effect of any of such exercises
But really, in every lighting project I'm bothered having to arrange tags that should be one.

Multi-category tags don't work with any spatial elements: Areas, Rooms, Spaces, Zones.
That was my next fear (if i should resolve the problem to get the parameters in) if it actually works.
So probably time to give up. If someone comes up with an idea, I'll try again.
Thanks to everyone who chimed in.

That should be the first thing you looked at before anything else.
True.... but unfortunately this wasn't clear from the beginning. At least not to me.
Even if it seems impossible at first, it still is worth looking into it. People also used to say flying is not possible.... ![]()
And I learned a bit about multi-category tags. That is not nothing.
I thought the goal was to pull lighting level and lighting power density into a Space Tag? Did I misunderstand? I thought that was the reason you were thinking Multicategory. If lighting level and lighting power density could be pulled from a Space, then a Multicategory Tag would not be necessary. A Space Tag would work. That was the direction I was headed. Whether or not I could get there is questionable. I'd have to work through it and see.
