Masses family lose their mass floors once inside a group definition

I have a group definition with a mass inside, some walls, etc.

 

I edit the group and add a floor mass to the mass. The mass properly shows the square footage.

 

Once I save and exit the group, only that instance mass has square footage.

 

When I edit another group instance and do the same, (thinking that floor mass settings are instance based, and do not propagate by group type) the newly edited mass shows the proper SF, however, all other instances of the same group go back to 0SF, the mass floor is gone.

 

 

Any idea what is going on?

 

Thanks

This issue happens with both in-place and family masses....

 

There is no way to have *all* masses in the same group definition, have mass floors...

 

Thank you

I'm not following. Groups can't include Mass Floors, so how would a Group carry over Mass Floor info?

@gsucci

It sounds logical to me. A mass floor needs two defining factors: a mass and a level. What would happen to a mass floor in a group if the group is moved yo a different elevation?

OR,

 

they could have behaved just like they do outside groups, when they are being cut at whichever project level you indicate in the Mass Floor panel.

 

Anyways, the answer is: mass floors are not supported by groups, which I did not know...

 

Thank you for your help,

PS: is this limitation documented anywhere? just curious...

...also, for what it's worth: "Gross Floor Area" is a parameter of the mass, not the mass floor.

Are you saying geometry can flex inside groups?  That would go against the whole idea of having groups.  Thus, I think the exclusion of Mass Floors from groups is by-design, not a limitation.

Geometry??? I thought we were talking about Mass Floors - not Mass Floors converted to Floors (a..k.a. Geometry)? Floors can be included in Groups.

Yes I am talking about mass floors.  When you slice a mass with levels you get them.  So think about when you move a mass with tilted surfaces vertically, the boundaries and the areas of the mass floors change accordingly.  That is the change that I say cannot be included in a group.

I thought walls inside groups can be extended and joined on a group-instance by group-instance base, so yes, geometry varies within the same group definition... Does it not? Maybe I am wrong...

 

But this is why groups are such a nightmare to work with, because their elements "interact" with the surroundings, and many times they "break" and Revit creates duplicated copies with new names?

 

Thank you

Barth,

I have never mentioned the "Gross Floor Area" parameter.

 

All,

Now that I think of it, Mass Floors are indeed cut inside a group. So, in a sense they *are* supported by groups, but you can cut the mass only inside one instance of the group. When you do so, schedules will list the mass floor within that one group.

 

If you edit another instance of the group and create another mass floor over there, the one inside the first group will disappear.

 

So, this is kind of confusing, because if mass floor are not supported by groups, you should never be able to cut one within a group.

 

Thank you

regards

No, you did not say "Gross Floor Area", but what you did say was “the newly edited mass shows the proper SF, however, all other instances of the same group go back to 0SF, the mass floor is gone”. This describes what happens with the “Gross Floor Area” perfectly.  But, like I said: I only mentioned it for what it’s worth.
