Sketchup Round Corner [repack] Crack Top Link

Often, simply drawing a single line across the "crack" or over an existing edge will trigger SketchUp to "heal" the face and fill the hole.

SketchUp has a well-known internal limitation where it struggles to create faces with edges shorter than approximately 1/16 of an inch (or 1mm). If your rounding radius is small, or the segments are highly detailed, the plugin tries to generate tiny faces. SketchUp fails to close these loops, leaving visible "cracks" or holes.

If the top face of your model is even slightly unaligned or warped, the rounding tool cannot cleanly connect the arc segments to the top face. This forces the geometry to twist and tear.

Here is why your SketchUp model is cracking at the top and exactly how to fix it. Why SketchUp Faces "Crack" When Rounding Corners

Creating smooth, rounded edges in SketchUp is essential for realistic 3D models. However, using plugins like Fredo6's or CornerEditor often results in a frustrating glitch: the "crack top" phenomenon. This issue manifests as open gaps, missing faces, or shattered geometry on the top surfaces of your model after running the script. sketchup round corner crack top

To help you get this sorted out right away, could you tell me you are using, and whether this is a commercial extension like FredoCorner or the classic RoundCorner ?

How to Fix the SketchUp Round Corner Crack Top Issue: Complete Geometry Guide

If you are using the popular Fredo6 RoundCorner plugin, the crack often happens because the corner parameters are too complex for the given space.

Are you using or a different extension?

The Round Corner plugin is part of the Fredo6 collection, which relies on a separate library called LibFredo6 . If LibFredo6 is missing, outdated, or corrupted, Round Corner (and other Fredo6 tools) will malfunction, leading to errors or preventing execution entirely.

If you've ever typed "sketchup round corner crack top" into a search engine, you know the frustration firsthand. You're not alone. This seemingly minor issue—the failure of a rounded edge to properly merge with a connecting face—is a classic stumbling block in SketchUp. It's a challenge that can turn the final step of a project into a major, time-consuming repair job.

If you are rounding a tight corner, lower the segment count in your plugin settings (e.g., reduce it from 6 segments to 3 or 4).

If the crack has already occurred and you do not want to redo your work, you can repair the missing top mesh manually.
