Ensure it is a component, not just a group.
Experiencing a geometric crack while rounding corners in SketchUp is a rite of passage for every 3D modeler. It is not a flaw in your skill, but rather an architectural constraint of the software's engine. By embracing the scale-up trick, standardizing your segment counts, and utilizing robust extensions like FredoCorner, you can banish open seams from your workflow entirely and achieve pristine, photo-ready bevels every time.

SketchUp has difficulty creating very tiny faces (under roughly 1/16th of an inch). When you use an extension like on a small object, the resulting arcs generate tiny segments that the software cannot bridge, leading to visible gaps or "cracks" in the mesh.
