3d object mirrored on 2d plane

[undo]

Hello all, this is my first posting ever; hope I get the etiquette right. I've just made a big leap from 04 to MEP-09. During my first session I must have toggled something on that I now cannot find to turn off. What I see is a duplicate object, in 2d, of the 3d object I'm working on. The 2d object is selectable. Can anyone tell me what I've done to deserve this? Please, Undo.

When the 2D item is selected, does it report as being a Multi-View block in the properties panel (CTRL + 1)? If yes, then this is normal and you should try looking up Multi-View Blocks and also Display Representations in the help files......

This is electrical conduit off the electrical palette that I'm working with. It doesn't report as an MvBlock. When the 2d pipe is selected the 3d pipe selects also. It must be some sort of view setting that is the culprit. Thanks for helping.

The problem did exist in the Display Representaion Config menus. Thanks for the help
