Hello everybody,
Is there anyone who knows how I can add to my room tag a label showing the distance between the floor finish (FFL) and the underside of the slab (floor in general) above? I've just managed to add a label showing the distance between the FFL and the ceiling (using a guide I've found on Revit Pure website - link below), but I don't seems to be able to work out how to do the same thing for the item mentioned above.
Any suggestion?

In a room tag you can add an "unbound height" label. Then, when you place the room, tag it, click the room (the diagonal lines, not the tag itself) and in the properties adjust the height of the room (see image).
To set the number you can do one of two things, just bind the top to the same level and enter an offset. Or, bind the top to the actual level you want (ie the U/S of slab above) and set the offset to 0. Both mothods will read out a number. All you may need to do is add some text in the family to the right of the label to state what the number is (eg: A.F.F, Above finished floor)
Hi Ryley,
It works. Thanks a lot.
Just one more question: is there a way to make the label read the level of the u/s of the item above (i.e. floor, beam, etc.) without having to manually input the offset from the base level or the level above?
Not entirely sure if I understood the question, but I think what you might be looking for is that you assign a shared parameter to your room category and associate a global (reporting) parameter to this which is labeled to a height dimension for the room? Still have to input all that manually, once set it should adjust though...
Hi Martijn,
The solution provided by Ryley works fine. If you carry on reading the thread though you'll see what I'm asking. I'd basically need to know whether there is a way to makee the process Ryley described automated by Revit, without having to manually set the heights to be read by the tag parameter.
You aren't just looking for enabling volume calculation right? (dropdown under architecture tab--> area) This would detect your floor etc. automatically, if set to room bouding...
No, I'm not talking about volumes. See may previous messages. It's the finished floor (FFL) to underside of slab above I'm talking about.
You want it as parameter for the room itself? Then you could use the global (reporting) parameter as mentioned above to get a level value to a certain point... if not, you could also create calculated parameter volume/area in the room tag to display room height for most situations that would work…
edit: added image, you can set the calculated value in room tag label (red) or you can add the shared parameter to the room tag label (green)
I'm not sure how effective this (volume/area) would be because rooms sometimes do not set their height correctly automatically. Also, depending on the model the ceiling may be room bounding, but they want up to the U/S of structure.
Ehmm, easiest is to just create a level for the u/s of the floor, perhaps align/lock it there, set the upper limit to that for the room. This is your unbounded height parameter. You can just use that in your label.
For beams lower then the floor, you could use the calculated parameter option above and subtract the difference (as input or some calculated value) to u/s of the floor from the unbounded height parameter. In the room tag that is, not the room itself.
That is probably the best solution.
I'm not too fussy about the downstand beams as they are placed in specific locations, which generally require more attention during the design coordination phase - we usually create specific section details for those. My main goal here is to be able to spot the finished floor to ceiling height and also the finished floor to u/s of slab height. And this seems to be a pretty good way to do it. Many thanks everybody!
You have to watch out and do it with care when using the room data for extracting a specific dimension to report in the room tag. I highly recommend not to use those and seek a different solution.
Using the Unbound Height and/or Calculated Height based on Volume and Area, may result inaccurate information in your case, especially when multiple disciplines are working with the same model. For the simple reason that the reported values of both the area and the volume are dependent on a set of variables which you may not have ownership of solely. Area and Volume calculation reported in the room tag are linked to Room Computation Setting (it can be center of wall/to face/to core …etc), the Computational height set in the level datum and the upper/base limit offsets of the rooms/spaces used by others for energy analysis, sizing of building systems…etc . You might sleep on some values wake up on different ones.
Hence the area calculated and reported in the room tag is not always the right area you are looking for...example:
There are more examples to give; however, if you read the above and compare the different values reported in image 1 and image 2 (volume/area/calculated and unbound height), and experiment with it a bit in Revit, you will get the point …

Hi RDAOU,
Thanks for the explanation and the examples you've shared. I never meant to use volume and area calculations in order to get that number. Too complicated and, as you said, too risky when working in a shared model environment.
As I said in my previous post, my main goal here is to find a (quick and easy) way that allows me to have the value of the distance between the finished floor (aka FFL) and the underside of the slab above.
If anyone knows how this can be done please let me know. Cheers
I don't get it. What does(/do) this room(/these rooms) look like in your situation?
If it's generic, creating a level at u/s of slab didn't work for you? If you place it on FFL level and set upper limit to u/s of floor level without any offsets. The room's Unbounded Height parameter can be put in tag label directly. This is unaffected by a room bounding ceiling. Other then that you can return as many height parameters in the tag through input or global parameters as you like...
I did accept your previous post as a solution. The latest messages were just in response to the other users who have commented. Thanks.
