The BZ (Bezier/Bezier/Bool) Toolbar is a SketchUp extension/toolset that adds tools for creating and editing curves (Bezier), advanced edges, and boolean-like operations not available in core SketchUp. It speeds up organic shapes and precise curve workflows.
, you can find extensive documentation and user guides for the Bezier Spline plugin
The BZ Toolbar is a free SketchUp extension that introduces advanced curve-drawing capabilities. While native SketchUp splits curves into distinct, uneditable segments immediately after creation, the BZ Toolbar generates "smart curves" that remain mathematically fluid and re-editable.

Perfect for organic modeling; these curves are strictly guided by a control polygon, ensuring maximum smoothness without sharp transitions.
Imagine you're designing a winding garden path. You'd want it to look natural, with flowing, organic curves. The is perfect for this. You can click points along the intended route, and the curve will create a smooth, continuous path that passes perfectly through each spot you selected. You'd want it to look natural, with flowing, organic curves
These tools allow you to transition seamlessly between straight lines, perfect geometric arcs, and organic Bezier curves within a single, continuous drawing operation.
These curves are often the easiest to master because they do not necessarily pass through the points you click. Instead, the control points act like magnets, pulling the curve towards them. Extension Warehouse Diverse Curve Types
The BZ Toolbar is a flagship tool of the "SketchUcation" community. Because Fredo6’s tools often rely on his "LibFredo6" library, using the SketchUcation Tools manager ensures all dependencies are installed automatically.
| Curve Type | Category | Key Features | Best For | | :--- | :--- | :--- | :--- | | | Polyline | A sequence of connected straight line segments | Quickly roughing out the overall shape of a path | | Classic Bézier | Spline (Non-Interpolating) | Uses directional "handles" and anchor points to define a curve | Creating highly precise, smooth curves with intuitive controls | | Uniform B-Spline | Spline (Non-Interpolating) | Defines a smoother, more fluid curve that doesn't pass through its control points, affected by an "Order" parameter for smoothness | Generating very smooth, natural-looking organic shapes (e.g., for landscape design or product ergonomics) | | Cubic Bézier | Spline (Interpolating) | A curve of the third order that does pass through its control points | Creating a custom contour that must intersect exactly with a set of predetermined points | | Catmull-Rom | Spline (Interpolating) | A curve that smoothly passes through all its control points | Designing pathways, roads, or other lines that need to follow a specific, defined route |
The toolbar is primarily used to create and manipulate various types of splines and curves that aren't possible with the standard Arc tool. Extension Warehouse Diverse Curve Types
