Mastering Curviloft: The Essential RBZ Plugin for SketchUp Professionals
If you’ve spent any significant time modeling in SketchUp, you’ve likely hit "the wall"—that moment where the native tools simply can’t handle complex, organic curves. Whether you’re trying to design a streamlined car body, a tensile fabric roof, or an ergonomic furniture piece, SketchUp’s default toolset often falls short.
This is where Curviloft comes in. Distributed as an RBZ file (the standard SketchUp extension format), Curviloft is widely considered one of the most powerful and essential plugins in the SketchUp ecosystem. Developed by the legendary Fredo6, it transforms SketchUp from a boxy architectural tool into a robust organic modeler.
In this guide, we’ll dive into what Curviloft is, how to install the RBZ file, and how to master its three primary functions. What is Curviloft?
Curviloft is a dedicated toolset for lofting and skinning. In geometry, lofting is the process of creating a 3D surface by connecting multiple 2D cross-sections. Curviloft takes this concept and applies it to SketchUp’s edge-and-face system with incredible precision.
The plugin is bundled as part of Fredo6’s suite and is essential for anyone moving beyond basic "push-pull" modeling. How to Install Curviloft RBZ
Installing Curviloft is straightforward, but it does have one specific requirement: LibFredo6.
Download the RBZ Files: You will need two files: the Curviloft.rbz plugin and the LibFredo6.rbz shared library (which provides the interface for all of Fredo6’s tools). Open SketchUp: Go to Extensions > Extension Manager.
Install: Click the Install Extension button and select the LibFredo6 RBZ first. Repeat the process for the Curviloft RBZ.
Restart: While not always required, restarting SketchUp ensures all menus and toolbars load correctly. The Three Pillars of Curviloft
Curviloft is divided into three main tools, each represented by a distinct icon on its toolbar. Understanding when to use which is the key to efficient modeling. 1. Loft by Spline
This is the most common use case. You select a series of separate contours (ribs), and Curviloft connects them to create a continuous skin.
Best for: Airplane wings, boat hulls, and custom furniture legs.
Pro Tip: Ensure your contours have a similar flow; Curviloft is smart, but it works best when the geometry is logical. 2. Loft Along Path
This functions like a supercharged version of SketchUp’s "Follow Me" tool. While "Follow Me" keeps the profile shape static as it moves along a path, Curviloft allows the profile to change shape from the start of the path to the end.
Best for: Spiraling ramps that widen as they go, or organic ductwork. 3. Skinning (Skin Contours)
This tool creates a surface based on a closed loop of edges (a "boundary"). It’s perfect for filling in complex gaps where the "Create Face" command fails.
Best for: Landscape topography, tensile structures, and filling in "holes" in complex 3D scans. Why Use Curviloft Over Native Tools?
While SketchUp has added more functionality over the years, Curviloft remains superior for three reasons:
Preview Mode: Before committing to a geometry, Curviloft shows you a "ghost" of the surface. You can adjust parameters, vertex matching, and segments in real-time.
Vertex Matching: You can manually tell the plugin which corner of "Shape A" should connect to which corner of "Shape B," preventing the "twisting" effect common in lesser plugins.
Geometry Cleanliness: Curviloft generates incredibly clean quad-based mesh patterns, making it much easier to use with other plugins like SubD or Artisan. Final Thoughts
The Curviloft RBZ is a game-changer for SketchUp users. It bridges the gap between architectural precision and organic fluidity. While it transitioned to a licensed (paid) model a few years ago, the sheer amount of time it saves—and the shapes it makes possible—makes it a mandatory investment for professional modelers.
Are you planning to use Curviloft for architectural structures or industrial product design?
SketchUp updates (e.g., from 2023 to 2024) often break Ruby plugins.
To preserve your setup:
Note: Mac users find this in ~/Library/Application Support/SketchUp.
Curviloft RBZ is a conceptual technique that combines curvilinear lofting principles with RBZ (Rule-Based Zoning) paradigms to generate complex freeform surfaces in computational design. This paper formalizes the theoretical foundations, algorithmic pipeline, mathematical formulations, implementation considerations, and applications in architecture, industrial design, and digital fabrication. We present a reference algorithm, complexity analysis, robustness strategies, and evaluation metrics, plus examples and potential extensions.
The search for "Curviloft RBZ" is the first step toward escaping the rigid, rectilinear world of native SketchUp. With this file installed, you transform SketchUp from a simple box-maker into a surfacing powerhouse capable of designing stadium roofs, ergonomic furniture, and rolling landscapes.

Master Curves with Curviloft: The Essential Guide for SketchUp Designers
Curviloft is a powerful, free extension for SketchUp that revolutionises how you create organic shapes and complex surfaces. If you have ever struggled to "fill the gaps" between curved edges or wanted to turn a series of ribs into a smooth skin, this is the tool you need. 🛠️ What is Curviloft?
Developed by the legendary Fredo6, Curviloft is a suite of three primary tools designed to generate surfaces from contours. It effectively brings NURBS-like lofting capabilities to SketchUp’s mesh-based environment. The Three Pillars of Curviloft:
Loft by Spline: Connects separate open or closed contours to create a continuous mesh.
Loft Along Path: Follows a guide curve (path) to sweep one or more profiles into a shape.
Skinning: Takes a closed loop of edges (even if they are non-planar) and "skins" them with a face. đź“Ą How to Install Curviloft (The RBZ File)
To get Curviloft running, you need to handle the .rbz file correctly through SketchUp’s Extension Manager.
Download LibFredo6: Curviloft requires this shared library to function. Download the latest version from the Sketchucation Plugin Store.
Download Curviloft: Grab the Curviloft RBZ file from the same source. Install via Extension Manager: Open SketchUp. Go to Extensions > Extension Manager. Click Install Extension.
Select your .rbz files (install LibFredo6 first, then Curviloft). Restart SketchUp: This ensures all toolbars load correctly. 🚀 Key Features and Workflow
Curviloft isn't just a "click and hope" tool; it offers a highly interactive preview mode that lets you tweak the geometry before committing. Interactive Preview
When you select your edges and run a Curviloft tool, the mesh appears in orange. You can click on the vertex nodes to re-order the flow of the geometry, ensuring there are no twists in your final model. Geometry Control
Interpolation: Adjust how "smooth" the curve is between your original ribs.
Vertex Matching: Manually align points between different-sized profiles to prevent "pinched" corners.
Thickness: While Curviloft creates surfaces, you can pair it with Fredo6’s Joint Push Pull to give your organic skins actual thickness. 💡 Best Practices for High-Quality Meshes
To get the best results from your RBZ installation, follow these professional tips:
Equalize Segments: If your starting contours have a similar number of segments, the resulting mesh will be much cleaner. Mastering Curviloft: The Essential RBZ Plugin for SketchUp
Explode Curves: Sometimes Curviloft performs better if you "Weld" or "Explode" your edges depending on whether you want a smooth surface or distinct facets.
Check Orientation: Ensure your profiles are facing the same direction to avoid the "milling" effect where the mesh twists 180 degrees. 🎯 Use Cases
Architecture: Creating tensile structures, complex rooflines, or vaulted ceilings.
Furniture Design: Designing ergonomic chair backs or flowing table legs.
Landscape: Modeling terrain transitions or winding pathways that change width.
Curviloft remains one of the most vital extensions for any SketchUp user looking to move beyond "box" modeling. By mastering this single RBZ file, you unlock the ability to model almost anything found in nature or high-end modern design.

Curviloft RBZ represents a pivotal intersection of computational geometry architectural intuition
, serving as a bridge between the rigid Cartesian constraints of traditional modeling and the fluid, organic complexities of the natural world The Philosophy of the Curve
At its core, Curviloft is not merely a tool for generating surfaces; it is a manifestation of parametric thinking
within a non-parametric environment. In the context of SketchUp, a software historically defined by its "push-pull" simplicity, Curviloft introduces a sophisticated logic of interpolation
. It challenges the designer to think in terms of "profiles" and "paths"—the skeletal essence of a form—rather than static volumes. This shifts the creative process from sculpting a solid to orchestrating a series of spatial relationships. Mathematical Elegance and User Intent
The brilliance of the RBZ plugin lies in its three primary methods: Lofting, Skinning, and Splining
. Each represents a different approach to solving the problem of "the space between." Loft by Spline
treats separate contours as keyframes in an animation, calculating a smooth transition that honors the integrity of each shape. Loft along Path
introduces a guiding trajectory, allowing for the creation of complex, sweeping geometries that mimic biological growth or aerodynamic flow.
addresses the boundary problem, filling the voids between intersecting lines to create a continuous mesh.
This mathematical rigor is hidden beneath a user interface that prioritizes visual feedback
. The ability to toggle between different interpolation methods in real-time allows for an iterative dialogue between the designer's intent and the software's geometric logic. Impact on Design Language
The democratization of these complex surface-generation tools has fundamentally altered the aesthetic output of modern 3D modeling. By lowering the barrier to entry for NURBS-like
(Non-Uniform Rational B-Splines) geometry, Curviloft has enabled designers to move beyond the "box" without requiring the steep learning curve of high-end engineering software. It empowers the architect to explore biomorphism topological fluidity
, ensuring that the digital model is no longer a limitation, but a catalyst for formal innovation.
In conclusion, Curviloft RBZ is more than a technical extension; it is an enabler of form
. It transforms the digital workspace into a more plastic medium, proving that even within the most structured software, there is always room for the grace of a curve. Should we explore the specific installation steps for the LibFredo6 library or dive into a for a specific lofting technique?
