Skinning is distinct in that it does not require separate "profile" shapes. Instead, you select a network of closed loops (like a grid) and the plugin fills the holes.
To use this extension, you must install two separate components from a reputable source like the SketchUcation PluginStore SketchUp Community LibFredo6.rbz:
Curviloft RBZ fuses geometric lofting and declarative rule-based modeling to produce controllable, fabrication-ready freeform surfaces. The framework balances fairness, manufacturability, and predictability via optimization and robust numerical methods, supporting applications across architecture and product design.
Click outside the model or press Enter again to generate the final geometry. The new surface will automatically be grouped to keep your model organized. Advanced Features and Settings

: Launch your SketchUp application.
: This is a plugin for SketchUp, a popular 3D modeling software. Curviloft allows users to create complex surfaces and shapes by lofting curves. Lofting is a technique used in 3D modeling where a surface is created by interpolating between a series of cross-sectional curves. This technique is particularly useful for designing smooth, organic shapes that would be difficult or impossible to create with basic extrusion or push/pull tools.
This comprehensive guide explores everything you need to know about Curviloft, from installation and core functionalities to advanced techniques and troubleshooting.
For architects, interior designers, and 3D modelers using SketchUp, creating complex organic shapes can be a challenge. Standard SketchUp tools excel at planar, rectilinear forms, but struggle with curves, surfaces, and complex geometries. This is where —installed via an .rbz file—becomes an indispensable tool. Skinning is distinct in that it does not
Curviloft completely rewrites the rules of what is possible within SketchUp. By understanding how to manipulate its profile lofts, path extrusions, and skinning networks, you can easily transition from rigid architectural concepts to sweeping, organic masterpieces. Download the .rbz file, keep your LibFredo6 updated, and start experimenting with curves to take your 3D modeling skills to the next level.
