There are topics with “purty pictures” in the SketchUp for Web categories that explain how to drag and drop files from your computer into the Trimble Connect panel of SketchUp for Web.
Why should SketchUp not disallow its customers to reuse their own files and refuse them all their rights and needs?
You can use the same folder system you used for the desktop version of SketchUp. The students can access that folder by clicking on the folder icon and then Insert. Click on the computer icon to access the folder on their computer. Or drag and drop from the computer to SketchUp.
