Components disappear while orbiting (black boxes stay)

amis

I started to optimize imported model with no components/groups at all. After I have replaced some things (ventilation) with components I noticed that they was disappearing while orbiting model. This happens with my other models as well and in big models it takes a few seconds before I can see all the components. Could this be problem with my grafic card or SU settings? Thank you

This is intended behavior when the GPU can't handle displaying the model smoothly during orbiting. This allows you to orbit more smoothly. Way back in the old days, SketchUp didn't do that and with complex models on low powered computers it was very difficult and slow to orbit.

By the way, this isn't a bug so I moved your post from the SketchUp Bugs forum.
