Base constraint changes on walls inside groups?

[Anonymous]

Hello,

I have a project with two buildings with 6 floors in each building. For now, all floors have the same elevation. This might change so each building have it's own set of levels. Bulding A have A01, A02, A03... Buiolding B Have B01, B02, B03... Since there is severeral apartment that is identical, apratments is made up off groups.

My problem is if i select all walls is building B and set the base constraint to B01 and press fininsh edting group. The base constraint changes back to A01??? Anyone know why this happens? Is it because A01 and B01 are on the same elvation?

Best regards,

Rickard

Try place in same plan view instead of elevation.

Hello,

No matter what I do, it doesn't seem to help. Even if I create two new walls in a view that has reference level to B01, group it and copy it out. The walls in the new group will belong to A01. I,ve attaced a video to show the problem.

Thanks for your time. I appreciate it!

Do you have anything at all in the project that is hosting to B01? Try creating a completely new wall with the host as B01 and see what happens. I will bet that if you created A01 first that you dont have anything hosting to B01.

There is a lot of things hosted to B 01 in the project. Walls that are outside of groups have no problem hosting to this level. It's when I group the walls the problem arises. So it looks like I can't have two levels with the same elevation, the group somehow referance the walls to Level A 01 no matter what I do. 

The problem I'm getting is that I can't find out how many meters I have of a certain wall type, since I really can't schedule stuff. It feels like a bug somehow. If I change the height of Level B 01 with 1 meter, everything works fine.

Since all residential units is made with groups it's really annoying this only happen when walls are placed inside groups.

Ungroup them.

If I ungroup I loose the benefits of using unfortunatly.

Put them into their own Group.

ungrop make changes according to your need and make a new group. then place wherever you need.

As I said, if I ungroup and make a new group I loose the whole point with using groups. The goups in this case is representing apartments, it's very important they are consistans around the whole project. 

One group represents one apartment type. If i need to change one type, all have to change. Otherwise I have to check every apartment type manually.

I see this was two years ago. We are having the same problem in Revit 2022. Was this solved?

Depends on how your group is constructed. Typically I would avoid having multiple level constraint in the group. So set all wall as unconnected and specify the height.
