Group elements attached to the wrong level.

[Anonymous]

Hi everybody,

I am working in a project with 2 towers 30 levels in each one.

I created two scope boxes for every tower.

I created 60 levels (30x2 towers) and associated the levels to every scope box.

Levels in every tower are coincident (same elevation).

Level +1 in tower 1 has the same elevation than Level +1 in tower2.

Level +2 in tower 1 has the same elevation than Level +2 in tower2…

I have created a group in Tower 2. All elements associated to levels in Tower 2 (Walls, Columns, Slabs).

When I copy this group to upper levels (Tower2) the elements in the copied groups are associated to levels from Tower 1 now. Only the original group keep the levels properly.

I think the problem is that levels in Tower 1 are coincident (same elevation) with the levels in Tower 2 and these levels were created before levels in Tower 2.

I would like all elements were properly associated.

Thank you in adavance.

I can replicate what you are describing (e.g. clipboard copy and paste Group to selected coincident Level), but I can change the Group's Reference Level afterwards.  Are you unable to?

We have gone through this issue, we found the problem where is this happens in our case.

The problem was our nested families which has generic models inside them.
We fixed using a temporary solution:

Cut the group and paste using selected level.

Please try and Cheers @Anonymous

Is this already resolved?
We experience the same problem. As we are script filling out building/level ID values inside our elements, this problem is really annoying.
Group ref. level can be changed but the base/top constraint of our walls keeps aligning wrong after copy-paste aligned.
