This article explores the technical issues related to corner rounding, the transition of the Fredo6 suite to a licensing model, and safe, legal alternatives for achieving smooth edges in SketchUp. Understanding the SketchUp RoundCorner Extension
The RoundCorner extension, developed by Fredo6, is a staple in the SketchUp community. It allows users to perform three primary operations:
Round Corners: Creates smooth, curved transitions between faces.
Sharp Corners: Rounds the edges but keeps the corner intersection sharp. Bevel Edges: Adds a flat chamfer or angled face to edges. It requires the LibFredo6 library to function correctly. Why Users Search for a "Crack"
Historically, Fredo6 plugins were free for many years. Recently, the developer moved toward a paid licensing model on SketchUcation to support ongoing development.
Searching for a "crack" for SketchUp extensions like RoundCorner
is highly discouraged, as these modified files often contain malware and are unnecessary given that the official versions are affordable or even free for certain users. Why You Shouldn't Use a "Crack" Security Risks sketchup round corner crack
: Files from unofficial "crack" sites often carry viruses or spyware that can compromise your computer and personal data. Stability Issues
: Cracks are frequently outdated and unstable, leading to constant SketchUp crashes or broken geometry. Official Support
: Using a crack means you cannot get help from the developer, Fredo6, or the SketchUcation community when the plugin fails. Legitimate Ways to Get RoundCorner
The developer, Fredo6, recently moved some of his popular plugins to a paid model after a decade of offering them for free. However, they remain highly accessible: Official Download : You can download the authentic version of RoundCorner directly from the SketchUcation PluginStore SketchUp Extension Warehouse Bundled Licenses
: If you use multiple Fredo6 tools (like JointPushPull or Curviloft), you can purchase a "Fredo6 Bundle" which is significantly more cost-effective than buying them individually. Trial Period
: Most of these plugins offer a trial period, allowing you to finish a project before deciding if you need a permanent license. Essential Requirements for Installation To run RoundCorner correctly, you must install the shared library first.

In SketchUp, "cracks" in rounded corners typically refer to geometry failures where the mesh pulls apart or fails to form a solid face after applying a rounding extension. This is most often caused by modeling at a scale too small for SketchUp’s internal tolerance. The Core Issue: Geometry "Cracking"
SketchUp has difficulty creating very tiny faces (under roughly 1/16th of an inch). When you use an extension like Fredo6’s RoundCorner on a small object, the resulting arcs generate tiny segments that the software cannot bridge, leading to visible gaps or "cracks" in the mesh. Common Causes
Scale Limits: Modeling at real-world scale for small items (like jewelry or small hardware) often causes the engine to ignore tiny edges, leaving holes.
Coplanar Failures: If the edges being rounded are not perfectly aligned or if the faces are slightly "off-plane" (even by a thousandth of a foot), the tool may create fragmented, "cracked" surfaces instead of smooth ones.
Softening Errors: Sometimes the geometry is actually there, but the edges aren't "softened" or "smoothed," making the curve look like a series of broken, faceted cracks rather than a continuous surface. Solutions and Best Practices
The "Dave Method" (Scaling Up): The most reliable fix is to turn your object into a component, make a copy, and scale that copy up by 100x or 1000x. Apply the RoundCorner tool to the large copy—where SketchUp can easily handle the math—then delete it. The original, small-scale component will reflect the now-perfect geometry without the cracks. The Good: Speed and Precision The primary selling
Clean the Mesh: Before rounding, use native tools or plugins like CleanUp3 to ensure there are no stray edges or tiny "stubs" that could interfere with the corner calculation.
Adjust Segments: Reducing the number of segments in your rounding settings can sometimes prevent the creation of segments so small that they "crack" the model.
Plugin Reinstallation: If the "crack" refers to a software error rather than geometry, ensuring you have the latest version of LibFredo6 and the specific extension is critical for modern SketchUp compatibility. Circles made of n sided ploygons cause endless issues
The primary selling point of RoundCorner is automation. In native SketchUp, rounding a corner on a simple box involves drawing arcs, tracing lines, and manually deleting waste—and that is just a cube. Imagine doing that on a complex piece of furniture.
RoundCorner handles this instantly. You simply select your edges, type in your radius, and hit enter.

Fix: Low-Poly proxy modeling. Create a low-resolution version of your model, round the corners, group it, and then hide it while you texture the high-res version.
