SketchUp struggles to create faces smaller than 1/16 of an inch. If your rounding radius is too small, SketchUp fails to close the geometry, creating visible "cracks."

RoundCorner is a plugin developed by Fredo6 for SketchUp that allows you to round, bevel, or fillet edges and corners of 3D shapes. It is highly valued because it handles complex, multi-edge junctions that SketchUp’s native "Follow Me" tool cannot easily manage. Understanding the "Round Corner Crack" Issue

Historically, Fredo6 plugins were free for many years. Recently, the developer moved toward a on SketchUcation to support ongoing development.

. Because the geometry is now large, SketchUp can successfully create all the small faces without gaps. Delete the Giant Copy

Use the Scale tool ( S ) to blow the duplicate up by 100x or 1000x.

If your plugin is working but leaving physical holes in your 3D models, use these professional modeling workflows to solve the issue. The "Scale Definition" Trick

Understanding why these geometric tears happen allows you to prevent them entirely and maintain clean, manifold geometry. Why SketchUp Corners "Crack"

Approximately $50 for a bundle of eight essential plugins (including RoundCorner, JointPushPull, and FredoScale).

If the rounding radius exceeds the distance to the next nearest edge or loop, the newly generated geometry will self-intersect. The plugin essentially runs out of physical room to draw the curve, causing the faces to fold over themselves, delete automatically, or tear apart. 3. Non-Manifold and Messy Base Geometry

When users search for a "SketchUp Round Corner crack," they are usually dealing with one of two distinct problems: (tearing mesh) or software licensing issues (expired plugins). 1. Geometric Cracking (Mesh Tearing)

Have you found a unique way to solve the round corner crack? Let us know in the comments below!

While FredoCorner is now part of the paid FredoTools suite, older versions of plugins (like RoundCorner 2.7) or limited trial versions might be found through official channels.

No, the crash is related to geometry density, not the SketchUp version. Newer versions help with RAM management, but a poorly prepared model will crash in any version.
