Personally, as an architect, I try to keep my models as clean as possible by using lightweight geometry and textures.
Actually, I got tired of dealing with heavy geometry and textures because my SketchUp sessions would gradually become slower on large production projects. I wanted to solve that problem for myself, so I built a tool.
Now, before every render or client delivery, I simply run an automatic scan on my models. It gives me instant feedback, helps me fix potential issues, and lets me see exactly where the model is heading, so I can stay on the safe side of model quality.
If you’d like to try it, it’s called nEVEn (uneven)
It currently supports SketchUp 2024+ on Windows.
