: The RoundCorner tool now includes a feature to detect overlaps. If the rounding radius is too large for the available face area, the geometry will "self-intersect," creating holes or "cracks".
If you are looking at a cracked top right now, do not panic. You do not need to re-model. Here are three repair methods, ranked from easiest to most advanced. sketchup round corner crack top
After running Round Corner, the top planar face develops weird lines, "cracks," or refuses to stay flat. It looks like the mesh is pinching at the center. : The RoundCorner tool now includes a feature
Fixing the "Cracked Top" in SketchUp Round Corner It’s a classic SketchUp headache: you run a Round Corner plugin to add that perfect bit of realism to your model, only to find the top face has "cracked," leaving behind jagged lines, missing geometry, or tiny holes. This usually happens because of SketchUp’s built-in 1/1000th-inch tolerance—it simply refuses to create edges that are too small. You do not need to re-model
