How to Fix and Prevent the SketchUp Round Corner Crack (Geometry Tearing)
If you are looking to move away from the Fredo6 ecosystem entirely to avoid licensing hurdles or technical glitches, several modern alternatives can achieve the exact same results. 1. Native SketchUp Tools (Follow Me / Outer Shell)
If you are using the older, legacy RoundCorner script, consider upgrading to . While RoundCorner processes offsets via a traditional projection method, FredoCorner uses a more advanced algorithm that handles complex corners, multi-edge intersections, and tight angles with far superior stability, natively mitigating edge cracks. Best Practices for Perfect Bevels
Because many users either cannot or do not want to pay for a license, several "plugin-free" techniques and alternatives have emerged as the new community "story" for rounding corners: sketchup round corner crack

SketchUp hates rounding very small edges. If your object is 1cm wide and you try a 0.5mm fillet, the engine struggles.
Cracks often appear when the rounding radius is too large for the available space. If two rounded edges overlap, the geometry "blows out," creating messy intersections. How to Fix and Prevent the SketchUp Round
Because SketchUp struggles with tiny faces, the easiest fix is to trick the software into working on a larger scale. Select your object or component. Activate the and pull the corner.
If cracks persist even at a massive scale, your base geometry is likely "dirty." Install the free extension (by ThomThom).
If you want a "proper feature"—the tool that professional SketchUp users actually use—it is (part of the FredoTools suite). This is almost certainly what you are looking for. If your object is 1cm wide and you try a 0
Yes, but it is risky. Always Right-click > Make Unique first. Rounding an instance that is flipped or scaled often causes the geometry to torsion-crack.
The most popular way to round edges is via Fredo6's RoundCorner or its successor, FredoCorner .
If you’ve seen your pristine cube turn into a jagged mess, you’ve met the "Round Corner Crack." Here is why it happens and the step-by-step fix.
