The BZ Toolbar, or Bezier Spline extension, is a cornerstone plugin for SketchUp users looking to move beyond basic straight lines and simple arcs. Created by Fredo6, it introduces a suite of advanced curve-creation tools that allow for parametric control over complex splines. 1. Getting Started: Installation The BZ Toolbar is part of the Bezier Spline extension.
Where to Download: Access it via the SketchUcation Plugin Store. You will also need the LibFredo6 shared library, which is a required background file for all Fredo6 plugins. How to Install:
Download the .rbz files for both Bezier Spline and LibFredo6.
In SketchUp, go to Extensions > Extension Manager > Install Extension and select the files. Restart SketchUp to initialize the toolbar. 2. Core Tools and Their Uses
Once installed, the toolbar provides several curve types, each suited for different modeling tasks:
Classic Bezier Curve: The standard curve defined by control points. Ideal for smooth, flowing shapes like table legs or architectural profiles.
Uniform B-Spline: Creates a curve that does not necessarily pass through all control points but is exceptionally smooth.
Cubic Bezier: A more mathematically complex curve often used in professional drafting for organic forms.
Polyline Divider: Converts a series of straight segments into a curve by adding vertices, which is helpful for "rounding off" sharp corners.
Convert to Guide: A utility tool that takes a drawn curve and converts it into individual guide segments for construction references. 3. Key Features and Workflow
Unlike SketchUp’s native arc tool, BZ Spline curves are parametric even after they are drawn.
Edit Mode: You can right-click any curve created with the BZ toolbar and select Edit Bezier Spline. This allows you to move, add, or delete control points to reshape the curve without starting over.
Precision Snapping: To create complex items like hoses or piping, place temporary guides in your model. The BZ tools will snap to these points, ensuring your curves align perfectly with existing geometry.
Integration: Advanced users often combine BZ Toolbar with other plugins like JointPushPull (for thickening curves) or Soap Skin & Bubble (for creating surfaces between curves) to model organic architecture like wavy roofs or modern furniture. 4. Troubleshooting Tips EDITING AND SIMPLIFYING CURVES in SketchUp with Curvizard
Before we look at the buttons, we need to understand the philosophy. SketchUp’s native tools are great for pushing and pulling geometry. But when you work with components (the building blocks of professional modeling), native SketchUp becomes clunky.
For example:
The SketchUp BZ Toolbar solves these specific pains. It is often called the "Swiss Army Knife" of SketchUp extensions because it is lightweight, free, and solves real-world problems instantly.
Because this toolbar is older, you may encounter hiccups.
Issue 1: "Undefined method" error on startup.

The Birth of BZ Toolbar
It was a typical day at the SketchUp offices in Mountain View, California. The team of developers was busy working on new features and tools for their popular 3D modeling software. Meanwhile, in Brazil, a group of passionate SketchUp users, led by a young architect named Bruno, were facing a common challenge. They loved using SketchUp, but they needed to work with Brazilian building codes and standards, which were not easily accessible within the software.
Bruno, being a skilled programmer, decided to take matters into his own hands. He started developing a custom toolbar for SketchUp that would cater to the specific needs of Brazilian architects and engineers. He called it the "BZ Toolbar" (BZ standing for Brasil, of course!).
The Early Days
The BZ Toolbar quickly gained popularity among Brazilian SketchUp users. It provided easy access to frequently used tools and commands, as well as some custom features that were not available in the standard SketchUp toolbar. Bruno and his team continued to improve and expand the toolbar, incorporating feedback from users and adding new features.
As the BZ Toolbar grew in popularity, it caught the attention of the SketchUp team. They were impressed by the quality and usefulness of the toolbar and saw its potential to benefit users worldwide. The SketchUp team decided to collaborate with Bruno and his team to integrate the BZ Toolbar into the main SketchUp software.
The Global Launch
The BZ Toolbar was officially launched as a part of SketchUp's toolbar library, making it available to users worldwide. Architects, engineers, and designers from all over the globe could now access the custom tools and features that were initially developed for the Brazilian market.
The BZ Toolbar became a model for future toolbar development, showcasing the power of community-driven innovation and collaboration. SketchUp users could now create and share their own custom toolbars, tailored to their specific needs and workflows.
The Legacy
Today, the BZ Toolbar remains a popular choice among SketchUp users, particularly in Brazil and other Portuguese-speaking countries. Bruno's initiative has inspired a new generation of developers and power users to create custom tools and plugins for SketchUp.
The BZ Toolbar's success story serves as a testament to the flexibility and extensibility of SketchUp, as well as the creativity and resourcefulness of its user community. Who knows what other innovative solutions will emerge from the SketchUp community in the future?
The BZ Toolbar is a specialized extension for SketchUp that provides advanced curve and spline creation tools, primarily through the popular Bezier Spline plugin by Fredo6. It allows users to draw, edit, and convert complex paths that are not available in native SketchUp tools. Key Features and Tools
The BZ Toolbar typically includes several spline types, each suited for different modeling tasks:
Classic Bezier Curves: standard curves where the shape is controlled by moving anchor points.
Catmull Splines: Smooth curves that pass directly through the points you click, often used for creating organic shapes like ropes or architectural paths. The BZ Toolbar , or Bezier Spline extension
Rational Bezier Curves: Allows for changing the "weight" of control points to influence the curve's intensity without moving the points themselves.
Conversion Tools: You can draw a rough approximation with one tool and later convert it to a different spline type (e.g., Catmull) using the toolbar's conversion options. Bezier Curve Tool - Extensions - SketchUp Community
In SketchUp, creating smooth, organic curves can be challenging with the native toolset. The SketchUp BZ Toolbar, also known as the Bezier Spline extension, is a critical add-on for designers needing advanced curve creation and editing capabilities. What is the SketchUp BZ Toolbar?
The BZ Toolbar is part of the Bezier Spline extension, primarily developed by the renowned community developer Fredo6. While SketchUp includes a basic "Bezier Curve Tool," it often lacks a dedicated toolbar or the variety of curve types required for complex architectural or interior designs. The BZ Toolbar fills this gap by providing a suite of tools for drawing and modifying: Classic Bezier Curves Splines and Polylines Advanced parametric shapes Key Features and Capabilities
The BZ Toolbar transforms how you handle geometry in SketchUp by offering more flexibility than the standard Arc tool.
Non-Destructive Editing: One of the biggest benefits is the ability to adjust curves after they have been drawn. You can move control points to refine shapes without having to delete and redraw them.
3D Precision: It draws curves in 3D space, which is essential for modeling complex forms like modern furniture or organic roofs.
Weight Control: For advanced users, tools like the Rational Bezier Curve allow you to change the "weight" of control points to influence how sharply the curve pulls toward them. How to Install the BZ Toolbar

However, here are the most likely explanations based on how your request could be interpreted:
The toolbar has roughly 15 tools, but we will focus on the "Big Four" that will change your modeling speed forever.
Once you know the individual tools, you combine them for professional workflows.
The "BZ Toolbar" generally refers to a collection of utilities created by the developer Burkhard (often denoted by the "BZ" initials). While there are several variations—most notably BZ_Scale and BZ_Tools—the toolbar is famous for solving one of SketchUp’s most frustrating limitations: Non-uniform scaling and advanced component manipulation.
In native SketchUp, when you use the Scale tool (S), you stretch everything uniformly or distort geometry in a way that breaks textures and angles. The BZ Toolbar gives you precise control to:
If you design casework, millwork, or need to resize imported CAD blocks (like doors or windows) to fit odd openings, the BZ Toolbar is your best friend.
