Instantly adds wall thickness to hollow, complex objects. 4. RoundCorner & FredoCorner (Procedural Edge Beveling)
LibFredo6 is not a modelling tool itself; it is a required by nearly all of Fredo6's extensions [7†L14-L17] [10†L4-L6]. Think of it as the engine that powers the car. It handles essential background tasks such as:
In the real world, no edge is perfectly sharp. Sharp 3D edges look fake and catch light poorly in renders.
Fredo6 continues to develop new tools, many of which address specific gaps in the modern workflow. sketchup plugin fredo6
: Performs basic 3D rounding of edges and corners along a specified radius.
What began as a series of free, passionate community projects has evolved into a professional suite of extensions that are widely considered "must-haves" for professionals. From architects and landscape designers to 3D artists and woodworkers, many users state that they cannot imagine their workflow without Fredo6's tools, saying things like "SketchUp is nothing without Fredo plugins" [11†L34-L36].
is a legendary developer in the SketchUp community, known for creating complex extensions that bridge the gap between basic modeling and advanced geometric manipulation . Most of his plugins require the LibFredo6 shared library Instantly adds wall thickness to hollow, complex objects
Enables precise drawing on curved surfaces, which is difficult with default SketchUp tools. Best For: Adding detail to complex organic models. 3. How to Install Fredo6 Plugins (2026)
Creating a tapered handrail:
Reinvents the native Scale tool by adding twisting, bending, tapering, and stretching capabilities. Think of it as the engine that powers the car
Fredo6 is a well-known developer of SketchUp plugins, renowned for creating tools that are both powerful and user-friendly. With a deep understanding of the SketchUp platform and a passion for 3D modeling, Fredo6 (whose real name is Fredo Phạm) has developed a wide range of plugins that cater to various aspects of 3D modeling, from animation and rendering to import/export and more.
Equally revolutionary is Curviloft, a plugin that addresses SketchUp’s historical struggle with organic surfaces. In the base software, creating a smooth skin over a series of disparate ribs or paths is nearly impossible. Curviloft automates this by generating surfaces based on selected contours, following logic similar to "lofting" in high-end CAD software like Rhino or Maya. This capability opened the door for architects to design "blob-style" structures and complex landscape topography directly within the SketchUp interface, democratizing advanced geometric modeling for a wider audience.
Furthermore, the challenge of creating complex organic forms—such as tensile fabric structures, terrain contours, or parametric facades—is elegantly solved by . SketchUp lacks native “lofting” or “skinning” capabilities; creating a smooth surface between two disparate curves typically requires painful manual stitching with the line tool. Curviloft automates this through three distinct algorithms: skinning along a path, covering between curves, and meshing from points. This plugin effectively gives SketchUp the surface modeling prowess of more expensive software like Rhino, enabling users to generate clean, watertight geometry from loose wireframes. The result is that architects can now conceptualize free-form canopies and organic roofs directly within their existing BIM workflow.
