Drawing not showing in Print Preview.

I just downloaded LibreCAD on my MacPro.  My drawing does not show in print preview.  Construction Line is not checked, I have tried fitting to view, and the printer is not grayed out in the levels.  I have LibreCAD on my windows computer and do not have this problem.  Help me please!

Maybe this could help?

As stated above, non of those suggestions worked.

Ok, I'm a dummy.  I found that I had a dot way out in the drawing that caused the problem.  I deleted the dot and all is well.
