This is the flagship tool. It generates a surface by bridging a sequence of parallel or semi-parallel cross-sectional curves (profiles).

🌀 It unlocks "BlobITECTURE" and ergonomic product design. Without this plugin, creating a comfortable curved chair or an arched bridge in SketchUp is nearly impossible for beginners. How to Install Curviloft

| Feature | Native SketchUp Tools | Curviloft Plugin | | :--- | :--- | :--- | | | The "Sandbox > From Contours" tool exists but is crude, often creating jagged geometry or failing on complex profiles. | Creates smooth, high-quality lofts with user-defined resolution. | | Topology | Difficult to create clean quad meshes; often results in triangulated messy geometry. | Generates clean topology ideal for subdivision modeling. | | Complex Curves | Requires extensive manual stitching of lines and faces. | Automates the creation of double-curved surfaces instantly. | | Editing | Native geometry is hard to modify once created. | Curviloft allows for re-generation if the input curves are modified (in certain modes). |

A for a specific object (like a vase or a car hood) Troubleshooting common errors like "invalid geometry"

: Similar to SketchUp's "Follow Me" tool but more advanced; it allows you to loft a shape along a specific rail curve while adding intermediate profiles.

At its core, Curviloft is a geometry generator. It takes simple lines or curves and calculates the "skin" or faces needed to connect them. While SketchUp is excellent for boxy, rectilinear shapes, it often struggles with curved transitions. Curviloft solves this by offering three primary methods of mesh generation. 1. Loft by Spline

It is always best to restart SketchUp after installing these tools to ensure the toolbars appear correctly. Pro Tips for Better Results

Curviloft is a mature, stable plugin, widely used since SketchUp 8. It is compatible with SketchUp 2017 and newer (including 2023/2024). It requires Fredo6’s LibFredo6 (a shared code library) to function.
