on cad doc info page, remove related objects Parts (WTParts)

I was looking there but it didn't seem like the one.  Must be this block.  Not clear which line(s) to comment out.  There is a single "Parts" table on the CAD Doc Related Objects page.

    <!-- Information page 3rd level navigation Related Objects menu options  -->
