Curviloft 18
Curviloft is a specialized script for SketchUp, developed by the prominent extension creator Fredo6, specifically designed for Loft and Skinning operations. It is a cornerstone tool for organic 3D modeling, allowing users to generate complex, smooth surfaces from contour lines and curves that would be difficult to create manually. Core Functionality
Curviloft typically provides three primary tools to generate 3D geometry from a selection of curves or points:
Loft by Spline: Joins separate open or closed contours to create a continuous surface "bridge".
Loft Along Path: Follows a specific "rail" curve to extrude profiles, essentially creating complex, swept shapes or custom pipes.
Skinning (Skin Contours): Creates a surface (a "skin") based on a closed set of boundary curves, filling the area with smooth geometry. Technical Requirements & Installation
To run Curviloft, several dependencies must be installed on your SketchUp system:
LibFredo6: This is a shared library required for all Fredo6 extensions to function.
Sketchucation ExtensionStore: While not always strictly required for operation, it is the primary platform for downloading and managing updates for the plugin.
Cost: While historically free, many Fredo6 plugins have moved to a licensed "Freemium" or paid model on the SketchUcation PluginStore to support ongoing development. Usage Tips
Clean Geometry: Ensure there are no "gaps" in your contours; small breaks in the lines can cause the script to fail or create "deleted vertex" errors.
Path Precision: For the "Loft Along Path" tool, the path should ideally be a single continuous curve (use tools like Curvizard to weld segments if necessary).
Previews: Curviloft generates a temporary preview grid, allowing you to adjust parameters like segment density and vertex matching before finalizing the geometry. Curviloft - SketchUcation
Curviloft is an essential extension for SketchUp, developed by Fredo6, that specializes in generating complex surfaces and organic shapes from contours. While "Curviloft 18" often refers to its compatibility with SketchUp 2018 or specific maintenance releases like version 1.8a, it remains a top-tier tool for architectural and organic modeling. Key Features & Tools
The extension is divided into three primary tools that handle different geometric challenges:
Loft by Spline: Creates a smooth surface across a series of separate contours or frames. It automatically generates intermediate edges to "skin" the space between lines.
Loft Along Path: Functions similarly to SketchUp’s "Follow Me" tool but with significantly more control. It allows you to loft shapes along a rail, supporting multiple intermediate profiles to vary the shape (e.g., transition from a square to a circle).
Skinning (Skin Contours): Generates a mesh over a closed or open frame of edges. This is highly effective for creating tensile structures, terrain, or complex architectural skins. Ease of Use & Workflow

Curviloft is a premier extension for SketchUp, developed by the prolific Fredo6, designed to bridge the gap between simple push-pull modeling and complex organic shapes. While the specific "Curviloft 18" naming likely refers to a maintenance release (like v1.8a) or a version compatible with SketchUp 2018, the core functionality remains the essential toolset for generating smooth surfaces from contours. Mastering the Curviloft Toolkit
Curviloft consists of three main operations that handle different geometric challenges:
Loft by Spline: Connects separate open or closed contours using smooth splines. This is ideal for joining different shapes—like a circle to a square—to create a fluid transition.
Loft along Path: Follows a rail curve to join profiles. This tool offers generation methods like Stretch, Offset, and Sweep, which are particularly useful for models requiring consistent thickness or complex winding paths.
Skinning: Creates surfaces bounded by 3 or 4 contiguous contours. It is the go-to choice for filling in the "skin" of an organic framework. Key Features for Precision Modeling Curviloft - SketchUcation
Curviloft is a powerful organic modeling extension for SketchUp, developed by the prolific plugin creator Fredo6 . It is widely considered an essential tool for architects and 3D designers who need to create complex, curved skins and surfaces that SketchUp’s native tools cannot easily handle .
While the "1.8" specifically refers to Curviloft v1.8a, a maintenance release from October 2018, the extension has since evolved to version 2.0a to ensure compatibility with modern SketchUp versions . Core Functionality
Curviloft operates by generating surfaces (skins) from existing contours and edges. It is divided into three primary methods, each accessible through a dedicated toolbar :
Loft by Spline: Joins separate, non-intersecting contours (open or closed) using smooth splines. For example, you can transition a hexagon into a circle by selecting both shapes and letting the tool bridge the gap with a smooth mesh .
Loft along Path: Connects contours along a specified rail curve. This is ideal for modeling objects like curvy chair legs, twisted structural beams, or ship hulls .
Skinning: Generates a surface bounded by three or four contiguous contours. This tool is often used to "patch" holes in complex geometry or create fabric-like surfaces, such as tied curtains or cushions . Key Technical Requirements Curviloft is a specialized script for SketchUp, developed
To use Curviloft effectively, users must install supporting libraries and manage licensing:
Curviloft is a powerful geometry-generation plugin for SketchUp, developed by the prolific developer Fredo6. Often referred to as "the lofting powerhouse," it is designed to bridge the gap between SketchUp’s native linear tools and the complex, organic shapes required in modern architecture and industrial design.
At its core, Curviloft automates the creation of curvilinear surfaces based on a set of selected contours. It functions through three primary modes: Loft by Splines, which connects separate open or closed profiles; Loft along Path, which follows a specific trajectory; and Skinning, which fills in a mesh framework of interconnected lines. This flexibility allows designers to create everything from flowing fabric structures and ergonomic furniture to complex rooflines that would be nearly impossible to model manually.
What sets Curviloft apart is its interactive interface. Before finalizing a shape, users can preview the geometry, adjust the "interpolation" (smoothness), and tweak the alignment of vertices. This non-destructive workflow allows for rapid iteration. While SketchUp is often criticized for its inability to handle high-poly organic forms, Curviloft empowers users to produce professional-grade parametric-style results within a lightweight environment.
Curviloft is a high-performance extension for SketchUp developed by Fredo6 that automates the creation of complex, organic surfaces from contours and paths. While "Curviloft 18" often refers to using the tool within SketchUp 2018, the plugin itself is a standalone suite of tools used for advanced 3D modeling. Core Tools in the Curviloft Suite
The extension provides three primary methods for surface generation:
Loft by Spline: Connects separate, non-touching open or closed contours using smooth splines to create a continuous surface.
Loft along Path: Joins multiple contours that are arranged along a specific "rail" curve or path.
Skinning: Generates a surface within a framework of 3 or 4 contiguous (touching) contour lines. Key Details for Users

Title: The Essential Bridge Between Art and Engineering in SketchUp
Rating: ★★★★★ (5/5) Compatibility Used: SketchUp Pro 2018 / 2019
The Bottom Line: If you do any organic modeling, complex roofs, or fabric structures in SketchUp, Curviloft isn't just a luxury—it is a necessity. While SketchUp’s native "Sandbox" tools are great for terrain, they are clumsy for precise organic shapes. Curviloft fills that gap perfectly.
What It Does: Curviloft creates surfaces from contours, but unlike the native "From Contours" tool, it gives you control over how the skin stretches between lines. It operates via three main modes:
- Loft by Spline: Connects a series of open or closed curves.
- Loft by Curves: Skins between two profile shapes.
- Skinning: Creates a surface across a network of crossing lines.
Pros:
- Intelligent Geometry: Native SketchUp tools often create jagged or triangulated messes when trying to bridge curves. Curviloft generates clean, flowing geometry that looks "smooth" rather than "computed."
- UI and Widgets: The plugin features a live preview widget. You can drag the vertices of your shape in real-time, watching the skin stretch and morph before you commit to the final geometry. This saves hours of "undo/redo" cycles.
- Topology Control: You can choose how the mesh is generated (e.g., triangular, square, or optimized grid). This makes applying materials and textures much easier later on.
- Fills the Void: It handles shapes that the "Follow Me" tool simply can't do, especially when the path and the profile are different sizes or shapes.
Cons:
- Learning Curve: The interface has a lot of buttons. For a beginner, distinguishing between "Loft by Spline" and "Loft by Curves" can be confusing at first. You will likely need to watch one or two YouTube tutorials to get the hang of it.
- Installation Hurdle: Curviloft relies on the LibFredo6 library. You cannot just install the plugin; you must install the library pack first. For users not used to the Extension Manager, this can be a minor frustration.
- Heavy Geometry: If you dial up the segmentation too high, the generated geometry can be heavy on your GPU. You have to be mindful of balancing smoothness vs. file size.
Best Use Cases:
- Creating complex stadium roofs or tensile fabric structures.
- Modeling custom furniture with curved, flowing legs.
- Blending two objects together (e.g., connecting a square duct to a round pipe).
Verdict: Curviloft 18 is one of the "Holy Trinity" of SketchUp plugins (alongside JointPushPull and RoundCorner). It transforms SketchUp from a boxy architectural tool into a legitimate organic modeler. It is stable, reliable, and once you learn it, you will wonder how you ever worked without it.
Highly recommended for intermediate to advanced users.

Troubleshooting Common CurviLoft 18 Errors
Even with version 18, users encounter issues. Here is how to solve them:
- "Loft Failed: Overlapping Normals" : This means your curves are facing opposite directions. Use "Reverse Faces" on one of your profile curves. CurviLoft 18 is sensitive to curve orientation.
- "The resulting geometry is jagged" : Increase the "Segments" slider in the CurviLoft 18 settings. Default is usually 12; try 24 or 48 for smoother results (be warned: this increases file size).
- "SketchUp freezes when I click Loft" : You likely have too many control points. Use the "Simplify Curve" tool within CurviLoft 18 to reduce the vertex count before lofting.
