Keep Objects Aligned When Copy to Selected Levels

[ChrisGamble]

I have a multi story building that is similar at each level. I modeled the first level and aligned everything to ref planes. But when I copy to selected levels the new elements are not aligned to the reference planes. Is there anything I can do about that? Maybe someone knows a better workflow to creating multi-story buildings are similar at each floor. I need to ability to change the wall types at each level, that why I am modeling this way.

Create a group and copy paste aligned it?

Let me rephrase myself. I aligned my objects and locked them to the reference plane, and when I copy to selected level the new objects aren't locked to the reference plane like the parent object is.

I understand. Copied elements have nothing to do with the constraints set for the original elements. They have the same alignments but all constraints will be lost. Create a group and you can include the constraining ref planes in it so they come together when you paste.

Ok, I recognized I mentioned nothing about locking the elements. Ill try and work with that, the only problem I see is then you have a ton of reference planes for every group and then you'd still have to align the reference planes together. But its still better than aligning multiple objects per group.
