Is there a newer version than this one I’m running?
The most recent desktop version is SketchUp 2023. There is no Make version after SketchUp 2017, though.
Of course there’s a newer version, even the logo is different now, we’re in 2023, but if you mean a newer version of the sketchup make version, the 2017 was the last one, now the free version is web based, the biggest difference is that you can’t install plug-ins there, only the pro and studio versions have that feature.
