We believe that this issue can be resolved by adding a support path to AutoCAD pointing to the CAD Pack menus folder.
Add the value shown above as a new support file search path, and click 'Apply' or 'OK'.
Load the CAD Pack menu, either by placing a product from the CAD Pack desktop application, or by using the CAD Pack Menu and Toolbar Loader in the CAD Pack program group. (Under All Programs/Herman Miller/CAD Pack/CAD Pack Menu and Toolbar Loader)
Once the toolbar and menu are loaded, close and reopen AutoCAD and the menu should now be showing.
