Curvizard is a powerful, interactive toolset for SketchUp, developed by Fredo6, designed to manipulate sequences of edges and curves. Unlike tools that draw new geometry, Curvizard focuses on refining existing "contours"—making it essential for cleaning up messy CAD imports or smoothing out jagged line work. Core Features
Curvizard provides a suite of functions to transform raw edges into clean, usable SketchUp curves:
Make Curve (Weld): Combines separate segments into a single SketchUp curve with optional auto-extension.
Simplify & Smooth: Reduces the number of segments in a curve based on angle or applies splines to average out sharp corners.
Cleanup Contour: Automatically removes small "spikes" and collinear edges that clutter models.
Reconstruct Geometry: Converts a sequence of edges back into a "true" SketchUp Arc, Circle, or Polygon so you can edit the segment count later.
Convert to Guides: Instantly turns any sequence of edges into construction lines. Download & Installation
The official and safest way to download Curvizard is through the SketchUcation PluginStore.
Required Dependencies: You must first install the LibFredo6 shared library (version 14.3b or higher) for the plugin to function. Download Format: The plugin is provided as an .rbz file.
Installation: Open SketchUp, go to Extensions > Extension Manager, and click Install Extension to select your downloaded file.
Restart: You must quit and restart SketchUp after installation for the tools to load properly. Pricing & Licensing
Curvizard is a paid extension but offers a 30-day free trial with full features.
Individual License: Approximately $15 for a perpetual license (covers 3 seats).
Bundle Option: It is also included in the Fredo6Bundle (8 plugins) for approximately $50. How to Use curvizard sketchup plugin download
Once installed, you can find the tools under Tools > Fredo6 Collection > Curvizard or through its dedicated toolbar icon.
Pre-selection: Select edges with the standard SketchUp selection tool before launching Curvizard to apply changes instantly.
Interactive Selection: If no edges are selected, launch the tool and use its custom cursor to pick edges across component or group boundaries.
Unlock the Power of Complex Curves in SketchUp with Curvizard
Are you tired of being limited by the basic curve tools in SketchUp? Do you struggle to create complex curves and shapes in your 3D models? Look no further than Curvizard, a powerful plugin that extends the capabilities of SketchUp's curve tools.
What is Curvizard?
Curvizard is a popular SketchUp plugin developed by SketchUp expert, Rafael Rivera. It allows users to create complex curves and shapes using a variety of advanced techniques, including Bezier curves, NURBS, and more. With Curvizard, you can create smooth, flowing curves that would be difficult or impossible to achieve with SketchUp's native tools.

Curvizard is an essential, free productivity tool for SketchUp, developed by the renowned plugin creator Fredo6. It is designed to "wizardize" curves—meaning it gives you a suite of cleanup and transformation tools for edges that SketchUp’s native toolset handles poorly.
You can download Curvizard from the Sketchupucation PluginStore. Note that you will also need to install the LibFredo6 shared library for it to function. Core Features
Curvizard acts as a "non-destructive" utility belt for edge management. Its primary functions include:
Make Curve: Seamlessly joins separate edge segments into a single "Curve" entity without changing their geometry.
Cleanup Contours: Removes stray vertices, merges colinear segments, and cleans up "micro-edges" that often cause issues with follow-me tools or 3D printing.
Simplify Contours: Reduces the number of segments in a curve while maintaining its overall shape—crucial for keeping your model's poly-count low and performance high.
Smooth/Unsmooth: Allows you to toggle the "Soft/Smooth" properties of edges en masse.
Convert to Arc/Circle: Attempts to recognize edge patterns and convert them into true SketchUp Arc or Circle entities. Why It’s "Solid" (The Review)
If you do any amount of organic modeling or work with imported CAD/terrain data, Curvizard is a "must-have." The Pros: Increased creative freedom : With Curvizard, you can
Workflow Speed: What would take 10 minutes of manual clicking (like finding a tiny break in a 50-segment line) takes seconds with the "Make Curve" or "Cleanup" tools.
Stability: Unlike some experimental plugins, Curvizard is extremely stable and works predictably across different SketchUp versions.
Integration: It integrates perfectly with other Fredo6 tools like Curviloft. If Curviloft is failing to generate a surface, running Curvizard's cleanup tool first almost always fixes the problem. The Cons:
Learning Curve: The icons are somewhat abstract. You’ll need to hover over them to read the tooltips or watch a quick tutorial to understand exactly what "Simplify" vs. "Smooth" will do to your specific geometry.
Dependency: The requirement to keep the LibFredo6 library updated can be a minor annoyance for users who prefer "plug-and-play" extensions.
Curvizard is a 5/5 utility. It doesn't create flashy geometry on its own, but it fixes the "broken" edges that prevent other tools from working. It is the vacuum cleaner of SketchUp—you don't realize how much mess you have until you use it.
How does Curvizard compare to other curve tools?
| Plugin | Strengths | Weaknesses | | :--- | :--- | :--- | | Curvizard | Specialized curve cleaning, welding, and simplification. Intuitive UI. | Paid (but affordable). | | LibFredo6 (Tools on Surface) | Great for curves on surfaces; free. | No dedicated weld/simplify for flat curves. | | Solid Inspector² | Checks solid groups for 3D printing. | Does not edit curve geometry. | | Curviloft | Creates surfaces from curves (lofting). | Does not repair curves; works best with pre-cleaned curves from Curvizard. |
Verdict: Use Curvizard alongside Curviloft and LibFredo6 for a complete organic modeling pipeline.
SketchUp is renowned for its intuitive push-pull workflow and precision in architectural modeling. However, its native toolset has a well-documented Achilles' heel: organic and curved geometry. While tools like Arc, Bezier, and Follow Me exist, managing hundreds or thousands of edge segments, cleaning imported CAD curves, or converting faceted polygons into smooth surfaces can be painfully tedious.
Enter Curvizard – a premium plugin developed by ThomThom (the legendary figure behind SketchUp extensions like Vertex Tools and Tools On Surface). Curvizard is not merely a curve generator; it is a complete curve management suite.
