In sketchup when I move the picture or even just move my mouse or zoom the various surfaces partially disapear.
In this simple example I drew a simple rectangle, then used the PushPull tool to raise the top. I also filled the top surface to make the problem easier to see, but the problem existed before that. In this picture, the only visible surface should be the yellow top of the box, and it should extend to the mans neck.
What is this behavior called?
Is this a problem with graphics card?
