Curvizard is a powerful extension for SketchUp, developed by the legendary , that transforms how you manage and manipulate curves and edge sequences. While SketchUp treats most curves as a series of straight segments, Curvizard provides a suite of interactive tools to weld, simplify, and smooth these edges into functional, clean geometry. Key Features & Toolset
Install the SketchUcation ExtensionStore v4.4.0+ to manage the plugin's license and updates. Installation Steps: Open SketchUp and go to Extensions > Extension Manager .
Design a modern chair: block out the seat and legs in SketchUp, use Curvizard to smooth armrests and seat contours, then fillet leg joints for a finished look—render to showcase the organic transitions.
| Feature | Function Description | | :--- | :--- | | | Seamlessly joins multiple selected edges into a single, continuous curve. It supports a pre-selection mode for quick access and operates across group boundaries. | | Simplify Contour | Reduces the number of vertices (control points) on a curve based on a user-defined angle threshold. This is invaluable for reducing model complexity and file size. | | Smooth Contour | Generates a refined, smoother curve from a jagged or segmented profile. This feature uses advanced spline algorithms with adjustable "average angle" parameters to control the smoothness precisely. | | Cleanup Contour | Automatically removes small spikes, redundant collinear edges, or other geometric anomalies from a selected path or outline. | | Reconstruct Arc/Circle/Polygon | Intelligently converts a fragmented sequence of edges back into a true, native SketchUp Arc, Circle, or Polygon. This allows you to adjust the number of segments later using SketchUp's entity info. | | Modify Edge Properties | Changes the attributes of selected edges to soft, smooth, hidden, or adjusts their cast shadows setting with a single click. | | Convert to Guides | Transforms a sequence of edges into construction lines, perfect for creating precise reference geometry without modifying the actual model. | curvizard sketchup plugin download
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.

Another Fredo6 classic, Curviloft generates surfaces from contours. Once you have cleaned and smoothed your curves with Curvizard, you use Curviloft to create skin-like membranes and organic transitions between different shapes. Many professionals use Curvizard for prep work and Curviloft for final surface generation. Curvizard is a powerful extension for SketchUp, developed
If you’ve ever struggled with messy imported lines or tried to weld dozens of tiny segments into a single smooth path, you know that SketchUp’s native curve tools can sometimes feel a bit limited. Enter , a essential extension by legendary developer Fredo6 .
SketchUp is renowned for its intuitive approach to 3D modeling. However, when it comes to organic design and complex curves, native SketchUp tools can quickly become a source of frustration. Once an imported CAD file arrives with hundreds of disjointed line segments or an imported topographic map converts smooth contours into a chaotic collection of edges, the model becomes messy and difficult to work with.
Allows you to batch-edit properties like "Soft," "Smooth," "Hidden," and "Cast Shadows" for selected lines. How to Download Curvizard Installation Steps: Open SketchUp and go to Extensions
As of 2022, Curvizard transitioned from a free plugin to a paid extension.
The solves this exact problem. Created by legendary developer Fredo6, this essential tool allows you to manipulate, smooth, and close curves with just a few clicks.
