I have a part that I am drawing which is truly made of three components.  However, I am not drawing this as an assembly because logistically for me it requires a single part number.  Of the three components two are identical and instead of drawing it twice I would like to mirror the part.  The problem I am running into is that when I mirror the part it merges with the rest of the model.  This prevents me from applying specific appearence properties to it.  I know that when making extrusions you can unselect the "merge bodies" option but I have yet to find anything similar in the mirror features menu.  Is there any way to prevent these bodies from merging?  Thanks in advance.
