What is Round Corner Crack Top?
The "Round Corner Crack Top" error occurs when using the "Round Corner" or "Fillet" tool in SketchUp to create rounded corners on a 3D model. The error causes the top surface of the model to become distorted or "cracked" when trying to apply a rounded corner.
Causes of Round Corner Crack Top
After analyzing various user reports and forums, the following causes have been identified:
- Complex Geometry: The "Round Corner Crack Top" error often occurs when trying to apply a rounded corner to a model with complex geometry, such as multiple intersecting surfaces or non-planar faces.
- Insufficient Faces: When a model has insufficient faces or is not properly divided, the "Round Corner" tool may struggle to create a smooth rounded corner, leading to a "cracked" top surface.
- Incorrect Tool Settings: Incorrect settings or tolerances in the "Round Corner" tool can also cause the error.
Solutions
The following solutions can help resolve the "Round Corner Crack Top" error:
- Simplify Geometry: Try simplifying the model's geometry by dividing complex faces or removing unnecessary details.
- Increase Faces: Increase the number of faces on the model by using the "Intersect Faces" or "Divide" tools to create more subdivisions.
- Adjust Tool Settings: Adjust the "Round Corner" tool settings, such as increasing the "Radius" or "Segments" values, to achieve a smoother rounded corner.
- Use Alternative Tools: Consider using alternative tools, such as the "Soften" or "Smooth" tools, to achieve a similar effect.
Workarounds
If the above solutions do not resolve the issue, the following workarounds can be tried:
- Manual Modeling: Manually model the rounded corner using the "Draw" and "Edit" tools.
- Plugins: Utilize third-party plugins, such as "Round Corner" or "Fillet Plus", which may offer more advanced features and better handling of complex geometry.
Conclusion
The "Round Corner Crack Top" error in SketchUp can be caused by complex geometry, insufficient faces, or incorrect tool settings. By simplifying geometry, increasing faces, adjusting tool settings, or using alternative tools, users can often resolve the issue. If necessary, workarounds such as manual modeling or using third-party plugins can also be employed.
Recommendations
- When working with complex models, try to simplify geometry and increase faces to prevent the "Round Corner Crack Top" error.
- Regularly update SketchUp and plugins to ensure access to the latest features and bug fixes.
- Consider using alternative tools or workarounds if the "Round Corner" tool is not producing the desired results.
Fixing the "Cracked Top" in SketchUp Round Corner It’s a classic SketchUp headache: you run a Round Corner plugin to add that perfect bit of realism to your model, only to find the top face has "cracked," leaving behind jagged lines, missing geometry, or tiny holes. This usually happens because of SketchUp’s built-in 1/1000th-inch tolerance—it simply refuses to create edges that are too small.
Here’s how to fix those cracks and prevent them from ruining your next project. 1. The "Dave Method" (Scaling Up)
The most common cause of "cracking" is working on a scale that is too small for the plugin to calculate the geometry correctly.
Make it a Component: Right-click your object and select Make Component.
Scale a Copy: Copy the component and scale it up by 100x or 1000x.
Apply Round Corner: Run the plugin on the giant version. Because the geometry is now large, SketchUp can easily create those tiny corner facets.
The Magic Part: Close the component. The original, small version will have inherited all the new, clean geometry without the cracks. 2. Check for Non-Planar Faces
If your top face isn't perfectly flat, the Round Corner tool will struggle to "heal" the surface, resulting in a fractured look. How can I fix the hole in this model - SketchUp Forums sketchup round corner crack top
The "top crack" issue in SketchUp's RoundCorner extension usually results from geometry scale, non-planar surfaces, or interrupted loops. Solutions include scaling the object up before rounding, manual face healing, or checking for hidden, problematic geometry. All the Ways to PATCH HOLES in SketchUp!
Seeing "cracks" or gaps on the top face of your SketchUp model after using a rounding tool is a common headache. It usually happens when the geometry gets too complex for the plugin to calculate cleanly, or when SketchUp's internal "tiny face" limit is triggered. Common Causes of "Cracks"
The "Tiny Face" Problem: SketchUp has a hard time creating faces smaller than ~1/16th of an inch (1.6mm). When you round a corner with many segments, the resulting triangles at the very top can be so small that SketchUp fails to fill them, leaving a "crack" or hole.
Tight Corner Overlap: If your rounding radius (offset) is larger than the distance to the next edge, the plugin "overflows" and creates overlapping or broken geometry.
Non-Planar Surfaces: If the top face isn't perfectly flat, the plugin may struggle to "stitch" the new rounded geometry to the existing face, resulting in visible seams or missing surfaces. How to Fix and Prevent Cracks
Conclusion
The SketchUp round corner crack top is not a bug in Fredo6’s plugin; it is a symptom of messy native SketchUp geometry. While frustrating, it is entirely fixable. Whether you choose to manually stitch the missing face, use the Intersect Faces repair, or prevent it by grouping your top face, you now have the toolkit to defeat the crack.
Remember: Clean geometry is happy geometry. Always run Solid Inspector before rounding, and apply fillets in small increments. Happy modeling!

Fixing the “Cracked Top” Nightmare: Perfecting Round Corner in SketchUp
We’ve all been there. You’ve just installed the Round Corner extension (by ThomThom) to soften those sharp edges. You click the button, watch the magic happen... and then you flip the model over.
The top face looks like a cracked desert floor. Introduction SketchUp is a popular 3D modeling software
Those unsightly seams, overlapping triangles, and "pinched" vertices on the flat top surface can ruin a otherwise perfect rendering. But don't worry—this isn't a bug in Round Corner; it’s usually a geometry logic issue.
Here is why that crack happens and how to fix it for a flawless fillet.
The "Crack Top" Issue: What Happens?
When you apply a RoundCorner (Fillet) operation to a shape—specifically a box or rectangle—the plugin successfully rounds the vertical edges. However, users frequently report that the top surface splits open or creates a jagged hole/crack right in the center of the face or at the corners.
Instead of a smooth, closed box, you are left with a model that looks like the top was ripped open.
Step 3: Reverse the Faces
Sometimes the face exists, but it is reversed (blue instead of white). Right-click the area > Reverse Faces.
Step 1: Identify the "Stray Geometry"
Often, the crack isn't a hole; it's a hidden edge or a reversed face. Zoom into the crack top.
- Toggle Hidden Geometry: Go to View > Hidden Geometry. Look for a bright blue line that shouldn't be there. If you see one, select it and delete it.
Option 2: Troubleshooting (Why Your Round Corner is "Cracking")
If you are trying to use the Fredo6 RoundCorner plugin and it is failing, creating gaps, or literally "cracking" your geometry, here is how to fix it:
Common Causes for Geometry Breaking:
- Scale Issues: SketchUp has a hard time creating small curves on very large or very small objects.
- Fix: Check your units. If you are modeling a coffee table but your units are set to Meters, the rounding might fail. Switch to Millimeters or Inches.
- Intersecting Geometry: If you try to round a corner where two lines cross or overlap without a clean intersection, the plugin will fail.
- Fix: Use the Eraser Tool to remove stray lines before rounding. Ensure your surface is a single, clean face.
- Plugin Expiration: If you are using an old version of the RoundCorner plugin, it might have expired or be conflicting with a new SketchUp version.
- Fix: Update the plugin via the Extension Manager or the SketchUcation Plugin Store.
How to Fix / Prevent the Crack
If you are running into this issue, try these troubleshooting steps before giving up on the model:
- Reduce the Segments: High-segment arcs (making the curve very smooth) exponentially increases the calculation load. If you are rounding a complex shape, lower the number of segments. A smoother look is not worth a broken model.
- Check the Radius: Ensure your radius isn't larger than the thickness of the material. It sounds obvious, but this is the #1 cause of top-face blowouts.
- Clean Up First: Run a "Cleanup" plugin or manually delete stray lines on the face before applying the tool.
- The "Stick" Trick: If the top face keeps cracking, draw a single diagonal line across the top face before running RoundCorner. Sometimes this helps the plugin understand the surface definition better.
