Running into this problem at my new firm who do primarily high rise condos.
Typical floors are done with groups combining structure and perimeter and such in separate groups. A problem that we are coming across is with columns being made part of the group when aligned to a grid I get the following message;
Group members had to be "moved to the project" (removed from their group instance) because they were not consistent with the group type definition.
By clicking ok it remove the members speciefied from the group and I can't seem to find a way to remedy it.
Thoughts and solutions would be appreciated.
