Mass floors substituting for level at same elevation bug

[KentBurns]

We have noticed what seems to be a bug, where we are working on a masterplan for a sloped site, so we have a number of sets of levels making up the Zones of the project. We're then massing, and using the Mass floors in each zone to get areas. All works lovely except we are noticing a strange behavour. It turns out that during the development two of the floor levels in two different zones are at the same Elevation. 

It seems that revit will substitute the one Zone's level with the other, it isn't doubling the areas, but it is substituting, and will schedule in the wrong zone. 

I assume under the hood the association with mass floors is done by elevation, and something is getting mixed up. 

I've checked the journals to confirm that I can see the users resetting the mass floors to the correct assignements, but not see any of them changing them to the substitution (so no one is doing it, accidentally or no, but not telling me)

This is in Revit 2022

Hopefully an easy fix.

I don't get it. "Zones"?  As in  HVAC Zones?  

[barthbradley]

I don't think you are talking HVAC.  I do see that it is replicable among your team. Can you give us the steps to replicate on our end - or post a file?  

[KentBurns]

Oh yeah not HVAC zones, like zones in a masterplan, not a revit element as such.

Well, you could attempt to have two levels at the same Elevation in your project, create a Mass, set the Mass Floor to be associated with the level you created second (that's a hunch at the moment) and it will eventually shift to the first one... Eventually is a bit hard to define though. We're not constantly checking. But over the course of a day

[barthbradley]

Okay, so I've got it now. Different Levels at the SAME Elevation.  So, you are saying that if you pick a Mass with Floors, Press Mass Floors and deselect one Level and choose another (at same Elevation), the Level shown under the Properties of the Mass Floor still read the "old" Floor Level?   

[KentBurns]

Almost there, 

Select your Mass, and set a Mass Floor at the Level you created second at the same elevation.

Eventually, it will be saying the level you created second, without you having done anything

Use a Scope box to scope Levels within each 'Zone'.

[KentBurns]

Thanks ToanDN, but that's something different.

[KentBurns]

Okay, once you have your Mass Floors applied, use Add to Set to put the Mass into a couple of design options and watch as it changes to the other level!

[KentBurns]

It's creating new design options that is switching the Mass Floors

[barthbradley]

Design Options??? You can't put Mass Floors into DOs.  I'm officially confused again.  he, he.  

[KentBurns]

Sure you can! you just can't put Levels in a DO. Give it a go, I set up a filter so I could see the magic happen when you add the mass into the option

[barthbradley]

Maybe you're not talking about Mass Floors. Maybe you are talking about Mass Floors converted to a Floors.

I said Mass Floor -not Mass or Floor conversion. 

[KentBurns]

Have you actually given it a go? or are you just assuming you're correct? I feel like we've diverted. But just select a mass, and add it into a design option, and the Mass floors will head in there as well.

I don't think so.  It is to limit the levels to not intersect the masses outside of the assigned scope box.

Yes, but we were talking specifically about Mass Floors.  You just threw Design Options into the equation and it got confusing again.  Masses can be added to DOs, but not Mass Floors ALONE.  Floor conversions from Mass Floor could be added to DOs though.  Anyways, just following along as best I can from Zones to Design Options. So far it's been quite a journey.  😉

Recreate mass floor insides the Design Option and pick the correct levels.
