Prem,
I'm guessing that your Model View Options is set to NOT show the taps in 3D. See the attached screenshot of the 15 library panel of the Model View Options (MVO) dialog. Your named MVO settings are saved with your views - thus this allows you to create faster-generating 3D views that do not show fawcets, knobs, etc and accurate ones which do show them.
I cannot remember, but I think it was about AC 13 that these settings moved to the MVO panel. Since you're using an AC 13 library part, it is probably responding to this option. Only know for sure that the 15 parts respond to this setting.
Cheers,
Karl
