I setup my ceiling plan so that I see all of the light fixtures on my sloped ceilings.
But I can't see my electrical switches, why?
I check my VV and the electrical componets is checked for visibility.
What do I have to do to make them show up?
Have you checked the View Range? The default RCP Cut Plane is at 7' - 6", which is well above the traditional light switch mounting height. Lower the Cut Plane to somewhere below the switch.
