Sorry, the troublesome plan section is PS3 @ 60" AFF. See page 4. Page 2 in layout shows how far I have to open the viewport to get the fill to go away. Then I used white masks to hide everything I don’t want to show.
Oh wow! So all of those guidelines do not show up in my layout nor were they in my model. I did see those lines when I first opened layout. When I relinked the model, those lines went away and then the gray area showed up.
Yes, I can do that on some pages, but not all because of where the viewport is. The clipping mask would cover the other viewport. I have this issue in with Pro Support. In the meantime, if I change it to Raster, the color fill goes away, but it doesn’t look as nice. Oh well. Hopefully it’s good enough for the clients.
