What is the you are trying to round?
If you have already run the plugin and noticed minor cracks on top, you can stitch the geometry back together manually. Grab the .
Use the to snap misaligned vertices back onto the correct axis, then re-run the plugin. 3. Adjust Plugin Parameters
Creates smooth, realistic geometry that is impossible to achieve manually in a reasonable timeframe. Cons: The "Crack Top" bug is real. It happens most often on complex corners or when the requested radius is too mathematically tight for the available space.
Use this if you applied Round Corner to the top edge of a cylinder/box and it created a pinched or broken face on the top. sketchup round corner crack top
: Copy the component and scale it up by 100x or 1000x.
: For organic models, sub-division surface modeling often yields cleaner rounded corners than traditional destructive follow-me operations.
SketchUp cannot safely create geometry or close faces when an edge is smaller than approximately 1/16 of an inch (or 1mm). If your rounding radius is small, the calculated facets fall below this threshold, causing SketchUp to ignore them and leave gaps or "cracks."
When rounding corners on surfaces that are not perfectly flat or perpendicular, the plugin may push vertices out of alignment. SketchUp cannot bridge these non-planar points with a single flat face, so it either leaves a hole or creates a web of messy triangles. What is the you are trying to round
Use the while holding Ctrl (Windows) or Option (Mac) to soften and smooth the new edge so it blends seamlessly. Recommended Extensions for Cleaner Edges
SketchUp will re-evaluate the perimeter and heal the missing face.

SketchUp is a popular 3D modeling software used by architects, interior designers, and makers. One of its useful features is the ability to create rounded corners and edges. However, some users may encounter a frustrating issue - a crack or gap at the top of a rounded corner. In this article, we'll explore the causes of this issue and provide solutions to fix the SketchUp round corner crack top. Use the to snap misaligned vertices back onto
The "SketchUp Round Corner Crack Top" problem is usually a symptom of three main issues: , micro-scale modeling that exceeds SketchUp's tolerance , or expired/unverified licensing . By understanding that the tool needs clean geometry and by utilizing the "Scale Up" trick for tiny objects, you can resolve the vast majority of these errors.
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)
Ensure your model is free of internal stray lines, reversed faces, or non-planar surfaces.
Sometimes the fix is in the user interface rather than the geometry. When you open the RoundCorner options panel, try adjusting these parameters:
What is the of the object you are rounding?
Draw a diagonal line across the top face where the crack appeared. If a face suddenly generates, the surface was non-planar.
