If you have landed on this page, you have likely stared at your screen in frustration. You’ve just applied a beautiful圆弧 (round corner) using Fredo6's Round Corner plugin (or the native Follow Me tool), only to zoom in and discover a disaster: a crack , a missing face, or a jagged "non-manifold" gap right at the top of your geometry.
When in doubt, scale up (to give math room) and increase segments (to smooth the math). Do not fight the crack; engineer your workflow to avoid it. Do you have a specific model that keeps cracking? Drop your file parameters (units, radius size, segment count) in the comments below for a custom diagnosis. sketchup round corner crack top
The "Round Corner Crack Top" usually happens because of . When two rounded edges meet at a 90-degree corner at the top of an object, the plugin creates two different arcs that try to occupy the same space. If the arc segments aren't perfectly matched, SketchUp’s inference engine throws an error, leaving a "crack" (a missing line or face). If you have landed on this page, you
