[Mac] SaveAs function frozen (everything grayed out so stuck!)

My son downloaded trial version of SketchUp; neither he nor I have ever used it before. He built a simple model and did SaveAs, and now our computer (MacPro running Yosemite) is frozen – he can’t save it and the SaveAs screen cannot be removed. How do we save his design so that we can print it?

Back to Save As: can you hit escape? Is it beach-balled SBBOD (google that)?

You can also hit command-N to create a new file, with the Save As panel open. But you have to try selecting all in the original window and pasting into the new window.

Can you upload to the 3dwarehouse: File->3dwarehouse->Share model. You can make it private if it’s something that he doesn’t want others to see.

Good luck.

Thank you; I’ll try these things!
