While looking for a "crack" for the popular RoundCorner plugin by Fredo6 often refers to finding a way to use it for free since it became a paid extension, there are safer and more reliable ways to achieve rounded edges in SketchUp without resorting to unofficial software cracks. SketchUp Community Official Plugin Options The most common plugin for this task is RoundCorner , which allows for rounding, sharp corners, and beveling. SketchUcation : RoundCorner currently costs approximately $12–$15 USD for a perpetual license (3 seats). 30-day free trial with full features is typically available. Requirements : You must install the
support library (which is free) for the extension to function. FredoCorner : A more advanced version, FredoCorner
, offers improved algorithms and the ability to undo rounding later, though it is also a paid plugin. SketchUp Community Free Native Alternatives
If you prefer not to purchase a plugin, you can achieve rounded corners using SketchUp’s built-in tools, though it requires more manual effort.
Fixing the "SketchUp Round Corner Crack" Issue: A Complete Guide
One of the most frustrating moments in SketchUp modeling is when you apply a rounding effect to a sharp edge, only to find visible gaps, holes, or "cracks" in the resulting geometry. This issue, often referred to as a SketchUp round corner crack, typically occurs because SketchUp struggles with very small edges or complex intersections.
Whether you are using native tools or popular extensions like Fredo6's RoundCorner or FredoCorner, here is how to identify and fix these geometry failures. 1. The Main Culprit: Small Face/Edge Tolerance
SketchUp has an internal precision limit of approximately 0.001 inches. When rounding a corner with a small radius or high segment count, the plugin may generate edges so short that SketchUp automatically "cleans them up" by deleting them, which creates a hole or crack. The Fix: The "Dave Method" (Scaling) Create a Component: Turn the object into a component.
Scale Up: Make a copy of that component and scale it up by 100x or 1000x.
Apply Rounding: Run your rounding tool on the giant version. Because the geometry is large, SketchUp can successfully create all the tiny segments.
Delete the Giant: Once finished, close the component and delete the large copy. The original small version will now contain the perfectly rounded geometry without cracks. 2. Radius Overlap and "Overflow"
If your rounding radius is larger than the space available on a face, the tool will "overflow" into adjacent segments, causing geometry to overlap or fail.
Check Your Radius: Ensure your offset is relevant to the model's dimensions.
Tight Corners: If a corner is 10mm but you set a 15mm radius, the plugin will create extra lines or red/green "error" segments. Reduce your radius to fit the available surface area. 3. Missing Geometry or Fragmented Shapes
Sometimes cracks appear because you haven't selected all the necessary boundary edges. All the Ways to PATCH HOLES in SketchUp!
Why Your SketchUp Round Corner Plugin is Failing (and How to Fix the "Cracks")
If you’ve ever tried to soften the edges of a 3D model only to find your geometry "cracking" open or leaving empty holes, you aren’t alone. In SketchUp, rounding corners is a classic challenge that often leads to jagged edges, missing faces, or the dreaded plugin crash.
Whether you are using Fredo6’s legendary RoundCorner or trying to do it manually, here is the complete guide to fixing "cracks" and keeping your models clean. 1. The "Tiny Geometry" Problem
The most common cause of cracks in rounded corners is SketchUp’s internal tolerance. SketchUp cannot create edges shorter than approximately 0.001 inches. When you apply a small radius to a corner, the resulting tiny faces often fail to form, leaving gaps.
The Fix: "The Dave Method"Instead of struggling with small scales, use this workflow: Turn your object into a Component.
Make a copy of that component and scale it up by 100x or 1000x. Apply the RoundCorner tool to the giant copy.
Delete the giant copy when finished. The original small component will now have perfect, crack-free rounded geometry. 2. Overlapping Geometry & Complex Joints
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.
The Fix: Adjust Your OffsetAlways check the Preview mode in RoundCorner. If you see red highlights or warnings about "Overlaps," your radius is too large for the shape. Reduce the offset until the preview looks clean before hitting "Generate". 3. Missing Face Holes
Sometimes the plugin rounds the edges but leaves the corner "empty" or hollow. This usually happens on non-orthogonal faces (angles that aren't 90 degrees) where the tool struggles to triangulate the corner.
The Fix: Manual StitchingIf only a single face is missing, you can often fix it by: Turning on Hidden Geometry (View > Hidden Geometry).
Using the Line tool to draw an edge over the gap. This usually forces SketchUp to "heal" the face. 4. Plugin "Cracks" (Expired or Not Working)
If the tool simply won't run or gives you an error message, it’s likely a versioning or licensing issue. As of recent updates, Fredo6 plugins like RoundCorner have moved to a paid model on SketchUcation. RoundCorner plugin issues - SketchUp Forum sketchup round corner crack
Searching for a "crack" for the popular SketchUp extension RoundCorner (or its successor FredoCorner) is not recommended.

Many users looking for "cracks" are actually facing license expiration or installation errors.
"Cracks" or missing faces in the SketchUp Round Corner plugin (by Fredo6) typically occur due to small geometry errors, where the resulting edges are smaller than SketchUp's minimum edge tolerance of approximately
of an inch. When these tiny segments cannot be created, the plugin fails to generate a complete face, leaving a "crack" or hole in the mesh. Core Reasons for Geometry "Cracks"
Small Edge Tolerance: SketchUp automatically "cleans up" edges that are too short ( <0.001is less than 0.001 mm) because of the limits of imprecise computer arithmetic.
High Segment Counts: Increasing the number of segments in a rounded corner makes each individual segment smaller. If the offset is already small, high segment counts often push the edge length below the tolerance threshold.
Overlapping Offsets: Cracks occur if the rounding radius is larger than the distance to the next adjacent edge or if you try to round corners that are already part of a curved area. Proven Fixes
The "Round Corner crack" isn't a bug in your model—it is a mathematical limitation of SketchUp's kernel. The most reliable fix is always scaling up (Step #2). If you remember nothing else, remember this: Make it big, round it, shrink it back.

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. Have a specific crack pattern not mentioned here
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
When searching for a "proper" feature to round corners in SketchUp, users are usually looking for a tool that is robust, doesn't break the geometry (creating cracks or black faces), and is easy to use.
While the term "crack" might refer to a specific plugin name you heard, it is more likely you are looking for the industry-standard solution to avoid "cracks" (geometry failures) when rounding corners.
Here is the breakdown of the proper features and plugins to achieve this:
If RoundCorner continues to crack, abandon the plugin. SketchUp's native Follow Me tool is bulletproof.
How to Round Corners Natively:
Note: This requires the edges to be a continuous loop. It creates perfect geometry 100% of the time without crashing, though it takes 30 seconds longer than pressing the RoundCorner button.
Problem: You successfully round the corner, but when you export to STL or DXF, SketchUp cracks.
Fix: You have too many polygons. Use Fredo6 Tools > Cleanup to weld stray vertices before exporting.
To fix the crack, you must understand the math. RoundCorner works by generating a massive amount of new geometry. A simple cube with a 1-inch fillet requires the software to delete the existing edge and replace it with dozens (sometimes hundreds) of tiny faces.
Here are the top 3 reasons for the crash:
If you are rounding corners on a complex object and getting cracks/holes, your geometry might not be a "Solid."
For SketchUp 2024 users: Ensure you have updated to the latest version of LibFredo6 (the dependency library). A "crack" is often just an outdated translation layer. Download the latest version from SketchUcation.
For Windows/Mac: RoundCorner is CPU-bound, not GPU-bound. A faster single-core clock speed (Intel i9 or AMD Ryzen 7) prevents freezes better than a fancy graphics card.
Q: Does SketchUp 2023 fix the RoundCorner crash? 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.
Q: Can I use RoundCorner on a component instance? 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.
Q: My screen shows a "Black Crack" (artifacts) after rounding. Help?
Go to Camera > Face Style > Monochrome. If the artifacts disappear, your texture is broken. Re-apply the material. If they remain, the geometry has "holey" faces—undo and use the Follow Me profile method instead.
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
: 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. Fredo "Corner" vs "RoundCorner" License - SketchUp Forums
The review wouldn't be honest without addressing the elephant in the room: geometry weight.
Because SketchUp is a mesh modeler (polygons), a round corner is actually a series of flat faces. RoundCorner works by generating many tiny segments to create the illusion of a curve.
