Curviloft Plugin Sketchup 2015 66 Link

Curviloft is a powerful script/plugin developed by Fredo6. It fills a significant gap in native SketchUp tools by allowing you to create complex organic shapes, lofts, and surfaces from a series of profile curves.

Why use it? Native SketchUp tools (like Follow Me) struggle with shapes that change profile or blend between different shapes. Curviloft excels at:


For the SketchUp 2015 user, Curviloft is not just a plugin; it is a gateway to a new style of modeling. It bridges the gap between the rigid, rectilinear world of standard SketchUp and the fluid, organic world of high-end design.

Whether you are modeling a custom piece of furniture, a concept car, or a sweeping architectural canopy, Curviloft provides the mathematical precision needed to "skin" your ideas with ease. By understanding its installation requirements (LibFredo6) and mastering its Lofting and Junction tools, you can unlock the full potential of SketchUp 2015.

: Ideal for creating a "bridge" or smooth transition between multiple parallel or non-parallel polylines. Loft Along Path

: Best for "long pieces" like custom railings or complex tubes where you extrude a profile along a specific path.

: Generates a surface (skin) from three or four bordering contours, useful for closing organic shapes.

| Feature | SketchUp 2015 (32-bit) | SketchUp 2015 (64-bit) | | :--- | :--- | :--- | | Max Geometry | ~500k faces (Curviloft will slow down after 200k) | ~2M faces (Curviloft handles 1M easily) | | Loft by Sections | Use 6-8 sections max | Use 15-20 sections | | Skinning Memory | Crashes with grids > 20x20 | Stable up to 50x50 grid | | Recommended Use | Small objects (furniture, details) | Large architecture, terrain, vehicles |

Pro Tip for "66": Always convert your Curviloft output into a Group immediately. Then right-click > Softening/Smoothing and set angle to 45°. This hides the triangulation lines without deleting geometry.


Why focus on SketchUp 2015? This version was a pivotal release in SketchUp's history. It marked the transition to 64-bit architecture for Windows and, crucially for plugin developers, the upgrade to Ruby 2.0.

This transition initially caused "breaking changes" for many older plugins. However, Curviloft was quickly updated to be compatible with Ruby 2.0, making it a stable and reliable choice for SketchUp 2015 users.

Important Note on Installation: Because SketchUp 2015 introduced stricter security measures and a new Ruby engine, installing Curviloft on this version requires two components:
