I think that SketchUp Team could find a way to render SKP files smaller. If you compare any mesh, textured or not, saved in SKP, to the same mesh saved in other app, like Blender, you’ll see that SKP file will always be larger. Like, significantly larger, even a couple times. I think this is because SketchUp always saves colour of every single edge separately and codes it in 8-bit RGB space (correct me if I’m wrong). It’s cool feature but in 99% cases we don’t need it. So my suggestion is to introduce a setting in Model Info like “Save edge colour (YES/NO)”. If set NO, it would reduce file size by all unnecessary edge colours and you won’t able to change it - graphic card will automatically impose black colour. Then only if you want to play with edge colours, which not that many people do (I do it sometimes), you’d have to set YES.
