Sketchup Round Corner Crack Top Best [ 2024 ]

If you try to round a 10-inch wide box with a 6-inch radius fillet, the math demands a curve that physically overlaps itself. The plugin attempts to force it, often resulting in the top face collapsing or cracking open because there isn't enough physical space for the curve to exist.

The "Round Corner Crack Top" error occurs when using the "Round Corner" or "Fillet" tool in SketchUp to create rounded corners on a 3D model. The error causes the top surface of the model to become distorted or "cracked" when trying to apply a rounded corner. sketchup round corner crack top

If the crack is a physical gap:

: If your "Offset" (the radius of the curve) is larger than the face itself, the geometry will overlap and "crack". Ensure your offset doesn't exceed the distance to the next edge. 4. Manual Patching If you try to round a 10-inch wide

If you’ve modeled a box, table, or curved object in SketchUp and noticed a thin crack or seam along a rounded corner on the top face, you’re not alone. That visual artifact often happens when edges, faces, or smoothing settings don’t align perfectly after rounding or chamfering. This post explains why it happens and gives clear, actionable steps to fix it so your model looks clean and exports correctly.

Is this a geometry limit of SketchUp, or am I missing a setting in the Round Corner parameters?
