((free)) Download — Round Corner Extension Sketchup Free
The RoundCorner extension for SketchUp, developed by Fredo6, is an essential tool for 3D modelers looking to add realism to their designs by softening sharp edges. While historically free, the extension now operates under a paid licensing model with a free trial period. Why Use the RoundCorner Extension?
Native SketchUp tools like "Follow Me" can create rounded edges, but they are often time-consuming and struggle with complex intersections. RoundCorner automates this process, offering three primary modes:
Round Corners: Creates smooth, curved transitions between faces.
Sharp Corners: Rounds edges but maintains a sharp point where multiple corners meet. Round Corner Extension Sketchup Free Download
Bevel Corners: Creates flat, angled chamfers instead of curves. Download and Installation Guide

I understand you’re looking for a Round Corner extension for SketchUp Free (the web-based version). However, there’s an important clarification to make first: The RoundCorner extension for SketchUp, developed by Fredo6,
- Round Corner (by Fredo6) is a powerful extension for rounding and beveling edges. It is not available for SketchUp Free (web) because the web version does not support third-party Ruby extensions — only the built-in tools and a few approved extensions from the SketchUp Extension Warehouse that are explicitly marked as compatible with “SketchUp Free.”
- Round Corner works only with SketchUp Pro 2017–2025 (desktop).
If you are using SketchUp Free (web) , here’s what you can do instead:
How to Use Round Corner
Once installed, you will find the toolbar under the Tools menu or as a floating toolbar.
- Select Edges: Use the selection tool to click the edges you want to round.
- Activate Tool: Click the Round Corner icon (looks like a rounded rectangle).
- Set Parameters: A dialog box will appear. Enter your desired Radius (how round the corner is).
- Preview and Apply: The tool will show a preview. If you are happy, click Enter or the checkmark to finalize the geometry.
Pro Tip: Always make your object a "Group" or "Component" before applying the rounding. This prevents the new geometry from sticking to other objects in your model. Round Corner (by Fredo6) is a powerful extension
3. TIG's Extrude Tools (Free)
TIG is another giant in the free plugin world. His tools allow for "Extrude Edges by Rails" which can simulate a rounded corner if you use a quarter-circle profile. Search for "TIG Weld" and "Extrude Tools" on SketchUcation.
Native Workaround in SketchUp Free:
- Use the Arc and Follow Me tools to manually create rounded corners.
- Or use the 2D Fillet feature in the built-in Sandbox or Solid Tools (limited).
- Consider using 3D Arc + Push/Pull for simple bevels.
2. Time-Saving
Imagine building a complex cabinet with 50 edges that need rounding. Doing this manually could take an hour. With the Round Corner extension, you can select all edges and apply the effect in under 10 seconds.
What is the Round Corner Extension?
Round Corner is a popular plugin developed by FredO6 (part of his FredoCorner toolset). It is designed to automatically apply round, bevel, or fillet contours to the edges of 3D objects in SketchUp.
In standard SketchUp, rounding an edge involves the "Follow Me" tool. While effective, "Follow Me" can be buggy on complex geometry and requires manual cleanup. Round Corner automates this entire process, allowing you to select a series of edges and convert them into smooth curves with a single click.
