I haven't used the DimXpert stuff, but you aren't getting any answers from the real experts, so I will throw out a few guesses.First, I would check in the "More Like This" box to the right. The thread "Attaching GTOL and datums to model dimensins in 2008" looks like it might be of interest. Second, try searching (upper right corner). Third, check under the View tab in SolidWorks. Maybe you need to have "All Annotations" set, or perhaps you have "Hide All Types" set.
When you insert the view from the View Palette, there is an option to insert with DimXpert dimensions in the Options area of the Palette. Check Import Annotations and check DimXpert Annotations.
