Curviloft remains a go-to extension for transforming curve networks into smooth, usable surfaces inside SketchUp. Recent updates focus on stability, smoother interpolation, better performance, and tighter compatibility with modern SketchUp releases—making it more reliable for complex organic modeling workflows. For best results, maintain clean, well-ordered profiles and pair Curviloft with curve-cleanup and subdivision tools.

Curviloft, developed by Fredo6, is one of the most essential extensions for organic and complex surface modeling in SketchUp. It automates the generation of surfaces (skins) from a set of contours or curves, filling a major gap in SketchUp’s native "Follow Me" and "Push/Pull" toolsets. 1. Key Functional Modules
Curviloft is comprised of three primary tools, each designed for specific geometric challenges:
Loft by Spline: Joins separate contours (edges or faces) with a smooth, continuous surface. It works by connecting corresponding vertices across the contours using spline interpolation.
Loft Along Path: Extrudes a profile (or multiple profiles) along a defined rail or path. Unlike the native Follow Me tool, it can handle multiple varying profiles and provides options like "Stretch," "Offset," and "Sweep" to control the geometry's thickness and orientation.
Skinning (Skin Over Framework): Generates a surface over a closed 3D frame or mesh of edges. This is particularly useful for complex architectural skins or landscape topology where a wireframe already exists. 2. Installation & Requirements
Curviloft is not a standalone plugin; it requires a shared library to function.
Prerequisite: You must first install LibFredo6 (v14.3b or above).
Source: The most reliable way to download and manage it is through the SketchUcation ExtensionStore. From a surface → produces cross-sections or structural
Format: It is typically provided as an .rbz file, which can be installed via SketchUp’s Extension Manager. 3. Licensing and Cost
Curviloft is a powerful SketchUp extension developed by Fredo6 that automates the creation of complex, organic surfaces from simple curve contours. It is widely considered an essential tool for organic modeling, filling the gap where SketchUp's native "Follow Me" tool falls short in handling non-uniform transitions. Core Functionality
The plugin provides three primary methods for generating geometry:
Loft by Spline: Joins separate open or closed contours using smooth splines to create a continuous skin.
Loft along Path: Extrudes a profile along a defined rail curve (path). It supports multiple contours and offers "Stretch," "Offset," and "Sweep" modes to control how the shape follows the path.
Skinning: Creates a surface bounded by 3 or 4 contiguous contours, effectively "stitching" together a frame of lines. Key Technical Details
Licensing: Since 2022, Curviloft has transitioned from a free tool to a paid extension. A perpetual license (valid for 3 seats) costs approximately $15, or it can be purchased as part of the Fredo6Bundle (8 plugins) for $50. A 30-day free trial is available.
Dependencies: To function, you must first install the LibFredo6 shared library (v14.3b or above) and the Sketchucation ExtensionStore (v4.4.0 or above).
Platform Support: Compatible with Windows and Mac OSX, supporting SketchUp 2017 through the latest SketchUp 2025 versions. Workflow & Best Practices Making a solid from a Curviloft skin - SketchUp Forums Manual Installation :

Last Updated: [Current Date]
If you are a SketchUp user who deals with organic modeling, complex facades, or parametric-like surfaces, you have almost certainly heard of Curviloft. Developed by the legendary French engineer and SketchUp plugin developer Christophe (a.k.a. ThomThom), Curviloft has been a cornerstone of the SketchUp extension ecosystem for nearly a decade.
But software evolves. SketchUp has moved from perpetual licenses to subscription models (SketchUp 2021–2025), and Apple Silicon (M1/M2/M3) has changed how plugins interact with memory. The question on every 3D artist’s mind is: Is Curviloft still relevant? Has there been a recent Curviloft plugin SketchUp update (upd)?
In this article, we will dissect the current state of Curviloft, cover the latest compatibility updates, explain how to ensure your version is up-to-date, and provide a masterclass on using its core functions: Loft, Skin, and Contour.
✅ Always check that LibFredo6 is also updated – Curviloft will show an error if not.
