Why does my project disappear when I try to print it?

When I try to print my project disappears. I am using Free Sketchup for web. I have printed other projects before with no problems.

It would help us help you if you share the .skp file.

I am not sure how to do that, but I finally got the file to print. On the "Print to PDF page where it
was disappearing, I clicked on “Scenes” in the print mode drop down box and the project re-
appeared so I could print it. Thanks for the4 help.

I wonder how the model was setup before you selected the scene. It is good you had made scenes.
