Use the tool to enlarge the object by 10x or 100x. Run the Round Corner plugin on the enlarged model. Scale the object back down by 0.1 or 0.01.
Fixing the "Round Corner Crack" on Top Faces in SketchUp Creating smooth, filleted edges in SketchUp is a standard part of 3D modeling. However, plugins like Fredo6's or Corner can occasionally leave a visible "crack," gap, or missing face on the top surface of your geometry.
SketchUp will safely retain the tiny faces once they are already created. 2. Adjust Vertex and Segment Settings in Fredo6 RoundCorner
When working in SketchUp, achieving smooth, realistic edges—especially on furniture, countertops, and architectural details—is essential for professional-grade models. If you are struggling with a "sketchup round corner crack top" issue, you are likely referring to unexpected geometry gaps, disjointed faces, or rendering breaks that occur when trying to use the popular plugin by Fredo6 or SketchUp's native tools. sketchup round corner crack top
Solving geometry tearing, missing faces, or visual "cracks" when using tools or plugins like RoundCorner Physical repairs:
If the top is a separate entity, group it first, then apply the RoundCorner tool.
Explain how to troubleshoot rendering glitches on rounded corners. Use the tool to enlarge the object by 10x or 100x
: Make a copy of that component and scale it up significantly (e.g., 100x or 1000x).
If you are trying to do this without plugins and your geometry is breaking (cracking):
In Fredo6 plugins, look for options relating to "Keep Corners" or "Grid Overlap." Toggling these can change how the plugin handles the transition between the vertical rounded edge and the flat top face. 3. Alternative Workflow: Native SketchUp Tools Fixing the "Round Corner Crack" on Top Faces
SketchUp is a surface modeler that relies on perfectly flat, coplanar polygons. When an extension modifies an edge, several factors can break the surrounding faces.
Select your object, right-click, and choose Make Group or Make Component . Duplicate and Scale: Make a copy of the component off to the side.
Extensions require clean, solid geometry to calculate paths accurately. If your top surface contains stray lines, internal faces, or un-merged vertices, the plugin loses track of the edge loop. This breaks the calculation right at the intersection of the top face. 3. Coplanar Edge Intersections
If the geometry of the meeting corners is too complex for the selected algorithm (Bezier vs. Circle), the plugin may force an intersection that tears the top face apart. 2. Step-by-Step Solutions to Fix and Prevent Cracks Method A: The "Scale Up" Trick (Most Common Fix)
