Problem with families changing reference levels

[Marcus.Isacsson]

Hi!

We have a problem where wall based families seem to change levels during uncertain circumstances and we don't understand why.

1. Wall based family placed on level 2 (plan 2)
2. Array those families (getting grouped) 
3. Now they changed to another level (entresolplan)

How can this be changed and/or avoided?

Hi,

Your issue may be "attached relationships in groups";

The top constraints of walls are commonly attached to levels or other hosts like floors and roofs, but these relationships should be avoided in groups.

and so try to let the wall top constrain to be unconnected height and try again the array/grouping.

try to make the array in plan , not in 3d or elevation
