In SketchUp, "cracks" or missing faces during rounding typically occur when working with small-scale geometry or complex intersections. This happens because SketchUp's internal engine struggles to create faces smaller than approximately 1/64 of an inch (approx. 0.4mm). Common Causes of Geometry "Cracks"
How to Round Corners Natively:
To understand the crack, you have to understand how SketchUp thinks. SketchUp is a surface modeler, not a solid modeler (like SolidWorks or Fusion 360). It uses "manifold edges"—meaning every edge should touch exactly two faces. sketchup round corner crack
