Hi Jack,
Unfortunately yes. SketchUp does not provide the option to transfer the contents of a previous Plugins folder to the next (new) version. However, what I do is simply copy the contents of the SketchUp 2021 Plugins folder and paste it in the SketchUp 2022 Plugins folder. If you don’t know the location of your Plugins folder you can find it by typing the following line into the input field of the Ruby Console and press Enter on the keyboard.
Sketchup.find_support_file(“Plugins/”)
You can open the Ruby Console with the menu Extensions > Developer > Ruby Console. Let me know if you have further questions.
Joe….
