— Essential for visual rendering, but you need to understand its mathematical limits to avoid broken geometry.
Reduce your radius by 20%, turn on "Soften Edges," and you’ll have a render-ready model in seconds.
Explain how to troubleshoot rendering glitches on rounded corners.
The gold standard for edge modification. It provides real-time previews and allows you to set precise offsets and segment counts.
If your offset distance is larger than the narrowest part of your top face, the geometry will overlap and implode. Ensure your radius is mathematically smaller than the surface area. 3. Manual Patching with Curviloft or Line Tool sketchup round corner crack top
instead of "Softened/Smoothed" to prevent the softening algorithm from creating visual artifacts or "two-tone" face issues. Use FredoCorner : Consider switching to FredoCorner
Use the to delete any unnecessary internal lines on the top face.
Run your plugin or manual Follow Me operation. (The faces will generate perfectly because the geometry is now large enough).
Ensure the top face is white (front face) and not blue/grey (reversed back face). Right-click and choose Reverse Faces if necessary, as plugins calculate vector offsets based on face orientation. Method 3: Adjust Plugin Parameters — Essential for visual rendering, but you need
Turn your geometry into a Component or Group before applying any rounding plugins. Right-click the base geometry and select Orient Faces to ensure all outward-facing surfaces are displaying their default white front color, rather than the bluish-gray back color. 3. Overlapping Offsets
Allows for precise manipulation of individual vertices, making it easy to fix un-planar top faces before rounding.
Those unsightly seams, overlapping triangles, and "pinched" vertices on the flat top surface can ruin a otherwise perfect rendering. But don't worry—this isn't a bug in Round Corner; it’s usually a geometry logic issue.
SketchUp cannot easily create faces or edges shorter than 0.001 inches (about 0.025 mm). If your model is small, or your rounding radius is tiny, the extension tries to generate geometry below this threshold. SketchUp ignores these tiny segments, leaving a literal hole or "crack" where the new face should be. 2. Non-Manifold or Dirty Geometry The gold standard for edge modification
If you are staring at a broken model right now, don't panic. Below is a systematic workflow to fix the crack, from simple tweaks to advanced professional methods.
The extension is powerful, but it hates Ngons that aren't perfectly planar. If the crack persists, use to weld the perimeter after rounding.
Ensure you are running the latest version of Fredo6's extensions (FredoCorner or RoundCorner) along with the updated LibFredo6 library. Newer versions feature optimized algorithms that handle complex top-face intersections more effectively.
When a plugin attempts to round a corner where multiple complex angles meet, it encounters several limitations:
