Mirror Groups Error Message

[msg4amer]

Each time I try to mirror a 3 story building, which I grouped, I get the following error message:

"Some of the groups you are trying to place contain inserts that are outside of hosts. These groups will not be copied."

Does anyone have an idea what this message means, and what can I do to resolve it?

This refers to hosted elements such as wall hosted plumbing fixtures etc. When mirrored they tend to not stay on the wall they were placed. To resolve the issue you'll either need to remove the hosted elements all together or replace them with non-hosted equivalents. This is easily done by making a new family non-hosted and cutting and pasting aligned from the hosted family.

Cheers.

Thanks Chris!

It seems that this error only happens when you group all the objects together. What I ended up doing is ungrouping it, then selecting the entire floor plan and then mirror it. Worked fine with no error messages.

Thanks,

Wes Macauley has written an excellent white paper on using groups in Revit, which includes useful tips when mirroring groups.
