If the rounding radius intersects with an existing edge on the top surface, the plugin must figure out how to merge the new arc with the old line. This often results in overlapping geometry or missing triangles at the apex of the corner. How to Fix the "Round Corner Crack" Method 1: The "Scale Up" Trick (Most Reliable)
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 plugins keep producing cracks, you can achieve a rounded corner by manually drawing arcs on the top surface, using the to sweep them around, or, as a last resort, using bump maps in rendering software to simulate the edge, rather than modeling it.
