Run a plugin like CleanUp³ by TT_Edition to remove stray vertices and duplicate edges before rounding.
The "Round Corner Crack Top" error in SketchUp can be caused by complex geometry, insufficient faces, or incorrect tool settings. By simplifying geometry, increasing faces, adjusting tool settings, or using alternative tools, users can often resolve the issue. If necessary, workarounds such as manual modeling or using third-party plugins can also be employed.
More segments create a smoother curve, but they also increase the likelihood of a geometric crack.
, which uses a more advanced algorithm designed to handle complex triangulation and repair issues better than the original RoundCorner. SketchUcation native SketchUp tools to round corners manually if the plugin continues to fail? RoundCorner plugin issues - SketchUp Forum 10 Nov 2015 — sketchup round corner crack top
Scale your tabletop up by a factor of 10 or 100 before running the rounding tool. Once the geometry is rounded, you can scale it back down to its original size. SketchUp will retain the smooth high-fidelity detail without generating errors. 2. Reversed or Exploded Faces
Sometimes, you need to give SketchUp a hint. Manually drawing a few simple lines can guide the plugin to create the correct faces.
Most users searching for this term are looking for the popular RoundCorner extension by Fredo6 . This tool allows you to round the edges and corners of 3D shapes along a 2D profile. Run a plugin like CleanUp³ by TT_Edition to
After analyzing various user reports and forums, the following causes have been identified:
If your corner radius offset is set larger than the available edge length of your tabletop, the algorithm will cause intersecting faces to "eat" into each other. This causes the geometry to fold in on itself and crack the top surface.
Hold down the key (Windows) or Option key (Mac) to toggle the "Soft To/Smooth" function. If necessary, workarounds such as manual modeling or
If your rounding radius is too large, the generated curve will overshoot the borders of the top face, destroying it. Reduce the offset distance.
If your plugin is leaving "cracks" or broken geometry on the top face of your SketchUp model, it’s usually due to tiny geometry errors or a conflict with the rounding algorithm. Quick Fixes for "Cracked" Faces
Use the to draw over one of the missing edges of the crack.
Keep your model lightweight. Heavy models filled with unpurged components suffer from calculation lag, which can cause plugins to miscalculate edge intersections.
Ensure your faces are not inverted. Right-click the top face and select Reverse Faces if the blue/gray back-face color is showing. The plugin performs best when working on the white "front" faces. Method C: Adjust Extension Parameters
