Has anybody encountered model information used in 3d documents disappearing sporadically? I have several details developed using a combination of floor plan marquee and 3d cut away, and annotated using additional 2d elements. Upon clicking the view, the 2d elements remain but the 3d model elements disappear. I am unable to view the 3d source as well. However, I am able to marquee a new area in the 2d window and visualize in 3d. This happens only on one particular VB file, which is about 115 mb in size. Other smaller (50 MB) files with similar details appear to be ok.
