A significant evolution of SketchUp’s flagship tool, this allows users to push or pull multiple faces simultaneously, even across curved surfaces—a feat impossible in the base software. RoundCorner:

| Feature | Native SketchUp | Fredo6 Suite | Rhinoceros + Grasshopper | | :--- | :--- | :--- | :--- | | | B-Rep (Polygon mesh) | B-Rep + Heuristic solvers | NURBS (Precise) | | SubD Support | None (requires Artisan/Vertex) | No native SubD (but Curvizard preps) | Yes (Rhino 7+ SubD) | | Offset Complexity | Planar faces only | Non-planar, self-intersecting, thickness | Any NURBS surface | | History/Associativity | None | None | Full (Data trees) | | Learning Gradient (1-10) | 2 | 5 | 9 |

are not just additions to SketchUp—they are transformative tools that redefine what is possible within the software. By investing time to learn FredoCorner, Curviloft, and Joint Push Pull, you can significantly speed up your workflow and create more complex, professional-quality models.

Download your desired tools (like Curviloft or FredoCorner) via the SketchUcation Extension Store inside SketchUp.

Reinvents the native Scale tool by adding twisting, bending, tapering, and stretching capabilities.

It gives you total control over the continuity, tension, and control points of lines, establishing the perfect foundation for Curviloft skins. The Shift to Premium: Understanding the Licensing Model

: Allows you to draw shapes (circles, lines, etc.) directly onto curved faces as if they were flat. The Verdict: Pros & Cons Pros Cons

SketchUp’s native toolkit operates on three geometric primitives: edges (line segments), faces (planar polygons), and groups/components (namespaced containers). The lack of native support for:

To prevent errors, Fredo6 plugins require a specific installation sequence. They rely on a shared library file to run.
