Before applying any rounding, scale your entire model up by 10x or 100x. This bypasses the "tiny face" limitation. Once the rounding is finished, scale it back down—the tiny faces will remain intact.
SketchUp has difficulty forming very small faces (under 1mm or 1/16 inch). When you round a corner with a high segment count, the resulting faces may be too small for SketchUp to "heal," leaving a gap or crack. sketchup round corner crack top
If your top face is cracking, follow these steps to achieve a clean finish: Before applying any rounding, scale your entire model
If your rounding radius (offset) is larger than the available surface area, the geometry will overlap and break the top face. 2. Best Solutions: FredoCorner vs. RoundCorner SketchUp has difficulty forming very small faces (under
The "crack top" issue usually stems from one of three problems:
