How to Save a SketchUp 2025 Model as an Older SKP Version

Notes

I generally prefer using newer software, but my instructor required assignments to be submitted in the 2019 SKP file format. Starting with SketchUp 2024, the built-in option to save to an older SKP version was removed, so I wrote down this workaround.

Use the Dezmo Save to older SketchUp Version plugin. It was shared as an attachment in the SketchUp forum: download the RBZ plugin. The discussion is here: Dezmo Save to older SketchUp Version.

Double-click the downloaded file to install it. The plugin is straightforward to use, so I will leave the rest to you.
