I’ve got the latest version of SketchUp, but my 3D warehouse won’t open at all. If I navigate to “window” and I click on “3D warehouse” nothing happens. And through “file” and “3d Warehouse” the options sharing components and model is grey.
I did use it in the new version, but since a couple of days it’s gone.
The sketchup installation might have messed up
In this case just uninstall then reinstall sketchup
Before you do this check your computer for a virus
Some viruses randomly delete files in your computer including files in software
It’s definately a multiple screen issue, I use multiple screens all the time. unfortunately I don’t have a second screen available now. And the keyboard combination you gave didn’t solve the problem. Resetting workspace didn’t help either.
