How to load drawings from SketchFree into SketchUp Pro?

I have several drawings created in SketchUp Free on a 2020 iMac. Obviously, the tools/options in Free are limited so I wanted to use the free files in the trail version of SketchUp Pro. How can I do this? A step by step process or contact phone number would be extremely helpful. Please reach out

Normally the files you create in SketchUp Free would be saved in your Trimble Connect cloud storage. In SketchUp Por you can go to the File Menu, click on Trimble Connect>Open Model… and access the files. Alternatively you could open SketchUp Free and use Download from the pancake menu in the upper left corner to download the .skp files to your computer. Then open them with File>Open.
