Have you tried force rebuild? Can you add another section view and see if that is coming or not?
ctrl+Q - rebuild
tray to edit quality of your drawing and set high quality or love, hope it helps
I am assuming the section views displayed correctly when they were created?
If the drawing is opened on a different computer, does the section view show?
If you create another section view in the same area, does this new view display?
Start a new drawing and recreate the section view; does the view display?
More drastic would be to suppress all components in the assembly, then unsuppress them.
Well just to update this thread guys. I had left work yesterday, of course checked in my files to PDM before I left. Then I come in this morning, reopen the drawing file, check it out, and what do you know.... my section views are now there, albeit with all of the original balloons missing. So I am not sure what the answer was on this one, but thanks for all of the comments. Every one was helpful, and may offer some insight for others in the future. Thanks.
