Settings
The Settings menu is in Extensions › SuSolid › Settings. Settings are saved in SketchUp, not in the model, so they apply to every model you open.
What you can set
- Add Solid Material
- Adds a material and its density (kg/m³) to the list used by Assign Solid Material. You can enter several in a row.
- Delete Material from the List
- Removes materials you don't use.
- Hide Solids
- Hides groups that are already solid while Analyse runs, so the non-solid ones are easier to see and fix. Turn it off again when you're done.
- Hide Non Intersecting Solids
- Hides solids that don't overlap anything while Intersection Check runs, so the overlapping ones are easier to see.
- Analyse Filter
- Chooses which colours Analyse shows. Useful when you want to ignore problems that don't affect solidity, such as coplanar (blue) or distorted (brown) faces.
- Buttons Select
- Chooses which buttons appear on the SuSolid toolbar. If you never weigh models, for example, remove Balance, Assign Weight and Assign Solid Material to make the toolbar shorter.
- Language
- English, Chinese, French, German, Italian or Spanish. Automatic follows SketchUp's language. Restart SketchUp after changing it.

Check the result
A new material appears in the Assign Solid Material list straight away. Toolbar and language changes show after you restart SketchUp.
