What command to display any differences in two objects which occupy exact same 3D location?

Hi,
V5
I have opened an old project and selected an object but it offers me a choice of 2 groups, I see no immediate difference, so having copy pasted them to a new project how can I get the differences made visible in a colour ?

Cheers

Hi Steve, I might be over simplifying this, can you put each one on a separate layer and give them their own color?—-Mark

Hi,
thats one way, means careful visual analysis in all four views at magnification, I just wondered if a command would do so and highlight differences such as the naked edge command does.

Cheers

I don’t think it works for Groups, but the SelDup command selects Perfect Duplicates, like stacked up objects that seem to be commonly coming in from imported DWG/DXF files.
