is an essential organic modeling extension for developed by Fredo6. It bridges the gap between SketchUp's native tools and complex surface modeling by generating skins and lofts from contours. As of early 2026, it remains a "must-have" for architects and designers dealing with non-planar faces and flowy geometry. Core Functionality

Mastering Curviloft in SketchUp: The Ultimate Guide to Organic 3D Modeling

Note: As of recent updates, Fredo6 plugins operate on a very affordable premium license model. You can test the plugin with a free trial, after which you will need to purchase a perpetual license key from SketchUcation to keep using it. Step-by-Step Tutorial: Creating Your First Loft

Curviloft is a dedicated script extension for SketchUp that generates surfaces from contours. Instead of manually drawing individual faces or relying on rigid native tools like Follow Me , Curviloft automates the creation of complex mesh networks. It reads selected curves and generates clean, customizable geometry between them.

You select a series of shapes spaced out in 3D space (for example, a small circle, a medium square, and a large oval). Curviloft will automatically skin a surface that morphs sequentially through each profile.

Unlike native SketchUp tools, which often require extensive "sandbox" modeling or manual vertex manipulation to create smooth curves, Curviloft automates the process, allowing for rapid creation of complex geometries. Key Features of Curviloft

Increase or decrease the number of segments along the loft to optimize your model’s file size versus its smoothness. How to Install Curviloft in SketchUp

Unlike SketchUp’s native Follow Me tool—which simply extrudes a single profile along a single path—Curviloft interpolates between multiple completely different profiles across space. It automatically calculates the geometry required to morph one shape into another smoothly. The Three Core Modeling Modes

Even the best tools can run into snags. Here are the most frequently reported problems and their solutions.

Curviloft requires a helper library to run. Follow these steps carefully to ensure a successful installation: Step 1: Install LibFredo6 (Prerequisite) Curviloft will not open without Fredo6's shared library.
