Troubleshooting the "Cracked Top" Issue in SketchUp's Round Corner (Fredo6)

The Problem: You’ve applied the Round Corner plugin (by Fredo6) to a flat surface or a box, expecting a smooth, continuous fillet. Instead, the top face generates a visible crack, a jagged line, or completely separates into two distinct halves. Visually, it looks like the rounded edge "breaks" the surface of your object.

In short: The circle of the fillet is trying to eat into a space where there is no more geometry. sketchup round corner crack top
