This is the flagship feature.

: Creates a surface by sweeping profiles along a dedicated rail curve or path. Unlike the native Follow Me tool, it allows for intermediate shape transitions along that path. Skinning (Skin Contours)

is a powerhouse extension for SketchUp, developed by the legendary Fredo6 , designed to generate complex surfaces and organic skins from existing contours . Whether you are creating advanced architectural forms or smooth, flowy geometry, Curviloft simplifies the process by joining separate lines or curves into clean 3D faces. Key Features of Curviloft

This guide provides a comprehensive overview of how to install, use, and master the full functionality of the Curviloft plugin. 1. What is the Curviloft Plugin?

Here is everything you need to know about downloading, installing, and using the full version of Curviloft. What is the Curviloft Plugin?

This is crucial. You must quit and restart SketchUp for the plugins to load properly. 3. Understanding the Three Core Curviloft Tools

Loft by Spline: This tool creates a surface by joining separate contours. If you have a series of ribs or cross-sections, Loft by Spline will weave a mesh across them to create a solid-looking form.

Note: This review is based on the stable version 2.8a as of early 2026. Always check for updates, as Fredo6 occasionally adds new features.

: Similar to the native "Follow Me" tool but far more sophisticated, this allows a shape to be extruded along a rail while adapting its form to stay consistent with the path’s curvature.

Once you master the basics, try these advanced moves:

"Loft by Spline" allows users to select a series of profile curves, and the algorithm generates a smooth surface that passes through each one. This is particularly useful for objects that change shape along an axis, such as a boat hull or a tapered architectural column. "Loft by Junction" differs by focusing on the connection between two shapes, creating a seamless transition that respects the topology of the start and end profiles. Finally, "Skinning" acts almost like a digital shrink-wrap, creating a surface over a network of crossed edges or curves. This specific function allows for the creation of complex tensile structures and organic forms that would be impossible to model using standard face-generation tools.
