Components' visibility is different than that of regular objects. To view a component on the screen, you need to specifically set its visibility.
The component disappears from the screen. In the tabular area, its icon is dimmed to indicate that the component is hidden.
NOTE: If you export or print out a drawing that has hidden components, these will not appear in the exported or printed outputs.
Since a component is not visible on the screen, you cannot access it there. Unhiding it takes place in the tabular area.
The component now appears at its place in the design of which it is part.
