Can any one tell me how to model Toriconical Head in Pv Elite...

Hi dhaval

It is quite simple. When you have the cone selected, there is a field near the bottom of the input screen called: 'Has Flare or Knuckle?'. Click on that field and a little check box appears. Check that box, and a dialogue screen will open up allowing you to state the knuckle and flare radii.
