Sketchup Round Corner Hot! Crack Top -
SketchUp cracks or missing faces during rounding occur when geometry falls below the application’s 0.025 mm tolerance limit, commonly resolved by scaling up the model by 100x or 1000x before applying the RoundCorner tool. Alternative solutions include reducing the segment count or switching to the more robust FredoCorner plugin for complex intersections.

Based on your search, it sounds like you are looking for a review of the plugin for SketchUp, specifically investigating a known issue where the geometry creates a "crack" or hole on the top surface after applying the rounding effect. sketchup round corner crack top
- Draw a low-poly box.
- Subdivide it 2 times.
- Shift+Click the top vertex to "smooth" it.
- Subdivide again. The crack will vanish because SubD creates continuous curvature, whereas Round Corner creates discrete geometric offsets.
- Scale Issues: SketchUp has a hard time creating small curves on very large or very small objects.
