The "top crack" issue in SketchUp's RoundCorner extension usually results from geometry scale, non-planar surfaces, or interrupted loops. Solutions include scaling the object up before rounding, manual face healing, or checking for hidden, problematic geometry. All the Ways to PATCH HOLES in SketchUp!
The Round Corner algorithm works by offsetting edges and trimming geometry. When you apply a fillet to a vertical edge that meets a flat top surface, the extension tries to blend the curve into the plane. If the relative to the thickness of the top slab, the geometry collapses into itself, creating "cracks." sketchup round corner crack top
This is the most common solution. If your top face is 10mm thick, do not use a 6mm rounding radius. The radius should never exceed half the thickness of the smallest adjacent face . The "top crack" issue in SketchUp's RoundCorner extension
In this comprehensive guide, we will dissect the causes of the dreaded "crack top," provide step-by-step repairs, and show you how to prevent it from ever happening again. The Round Corner algorithm works by offsetting edges
: If the top surface isn't perfectly flat, rounding the edges will force the geometry to twist, creating "cracks" or triangulated shards.
