The Eraser tool () isn't just an eraser. SketchUp's Eraser tool can remove geometry from your model, Smooth or Unsmooth entities, and even Hide parts of your model.
In SketchUp for iPad, the Eraser tool has 3 optional tool modes:
- Smooth () - Smoothing an edge adds shading and makes it's bounding edges look smooth.
- Unsmooth () - Converts any "Smoothed" geometry into visible geometry.
- Hide () - Hides the "erased" geometry but leaves any bounding facets as though the line were still there.
