Converts sequences of edges into true SketchUp Arcs, Circles, or Polygons, or applies spline-based smoothing to rough contours.
Curvizard is a robust geometry-tending plugin for SketchUp. Unlike SketchUp’s native tools, which require you to modify individual line segments one by one, Curvizard applies modifications to entire networks of lines simultaneously. Key Features
Uses splines to average out angles and create a more fluid appearance for jagged lines. curvizard sketchup plugin download
Open SketchUp, go to Extensions > Extension Manager , and click Install Extension to select your downloaded file.
Let's explore how Curvizard solves real-world modeling problems: Converts sequences of edges into true SketchUp Arcs,
To help me tailor this guide or troubleshoot any issues, let me know:
Every curve in SketchUp has a start and an end point. When using advanced plugins like Curviloft or Profile Builder, mismatched curve directions cause twisted geometry. Curvizard allows you to reverse or unify the direction of multiple curves simultaneously. 6. Simplify Contours Key Features Uses splines to average out angles
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.
Released more recently (January 2026) on the Extension Warehouse, Smart Spline takes a "Zero UI" approach to organic curves. It focuses on drawing gestures rather than parameter windows, providing a fluid, natural way to handle splines for furniture design and complex structures.
High-polygon curves from 3D warehouse models or terrain contours slow down SketchUp’s rendering engine.
You must first install LibFredo6, the shared library required for all Fredo6 plugins. Installation Steps:
