//free\\ — Sketchup Bz Toolbar

The BZ Toolbar (part of the Bezier Spline extension by Fredo6) is a powerful toolset for SketchUp designed to create and edit complex curves, polylines, and splines. While the native SketchUp Bezier tool is limited, the BZ Toolbar offers over a dozen curve types and advanced editing capabilities. 🛠️ How to Install and Set Up

To use the BZ Toolbar, you must install both the extension and its required library.

Download LibFredo6: This is the shared library required for all Fredo6 plugins.

Download Bezier Spline: Get the extension from the SketchUcation Plugin Store. Install via Extension Manager: In SketchUp, go to Extensions > Extension Manager.

Click Install Extension and select the downloaded .rbz files. Activate the Toolbar: Navigate to View > Toolbars. Check the box for BZ Toolbar or Bezier Spline. ✨ Key Features & Curve Types

The BZ Toolbar introduces several specialized tools that go beyond basic line drawing: Bezier Curve Tool - Extensions - SketchUp Community

The BZ Toolbar (often synonymous with the Bezier Spline extension by Fredo6) is a powerful, free toolset for SketchUp that allows you to draw and edit a wide variety of advanced curves and splines beyond the standard arc and circle tools. Key Features and Tools

The toolbar includes several specific curve types, each tailored for different design needs:

Classic Bezier Curve: Standard curves where you set control points to define the shape.

Catmull Spline: Excellent for creating smooth paths that pass exactly through your selected points—ideal for parametric walls or intricate lattices.

Uniform B-Spline: Creates smooth, continuous curves that are easier to manipulate for complex organic shapes.

Curve Editing/Conversion: A standout feature is the ability to right-click an existing curve to edit its points or convert a standard line into a Bezier curve. Installation Guide

Because this is a third-party extension, it is not built into SketchUp by default. Bezier Curve Tool - can't see toolbar in Sketchup Pro 2024 sketchup bz toolbar

BZ Toolbar (part of the Bezier Spline extension by Fredo6) is a essential tool for SketchUp users looking to move beyond basic straight-line geometry. While SketchUp is natively optimized for rectilinear forms, the BZ Toolbar introduces advanced mathematical curves—such as Bezier, Spline, and Polyline curves—directly into the 3D modeling workflow. The Role of BZ Toolbar in Precision Modeling

The core value of the BZ Toolbar lies in its ability to create complex, organic shapes that are otherwise difficult to execute with standard tools. It offers several distinct curve types: Classic Bezier Curves:

Ideal for smooth, flowing lines used in furniture design or organic architecture. Splines and Polylines: Provide more control points for intricate pathing. Conversion Tools:

One of its most powerful features is "BZ Convert to," which allows users to take a standard line drawn with the basic Pencil tool and transform it into a sophisticated spline. Improving Workflow and Geometry Control

Unlike the basic "Arc" or "Freehand" tools, the BZ Toolbar gives users granular control over segmentation

. You can specify the number of segments in a curve, which is critical for maintaining high-quality renders without slowing down the model's performance. For designers working on parametric-style projects—such as the iconic Cayan Tower—this plugin is often used to establish the "skeleton" of the structure before applying faces. Installation and Accessibility

The BZ Toolbar is generally available as a free extension. To use it effectively: Bezier Curve Tool - can't see toolbar in Sketchup Pro 2024

Here’s a sample review for SketchUp BZ Toolbar, written from the perspective of a SketchUp user (e.g., architect, 3D artist, or hobbyist). You can adjust the star rating and details based on your actual experience.

Title: A Handy Collection of Time-Savers, but Not Perfect
Rating: ⭐⭐⭐⭐☆ (4/5)

Review:
I’ve been using the SketchUp BZ Toolbar for a few weeks now, and overall, it’s a solid addition to my workflow. The toolbar bundles several useful scripts—mainly focusing on layer management, object snapping, and quick visibility toggles.

What I like:

  • The “isolate selected” feature is a lifesaver when working on complex models.
  • Layer switching feels faster than using SketchUp’s native dropdown menu.
  • Installation was straightforward (copied files to the Plugins folder).
  • No noticeable performance hit, even on large files.

What could be better:

  • The icon design looks a bit dated (feels like SketchUp 8 era).
  • No built-in tooltips or help menu—you have to remember what each icon does.
  • Occasionally conflicts with other extension toolbars if you have many installed.

Verdict:
If you do a lot of organizational work (layers, scenes, hiding/unhiding objects), the BZ Toolbar is worth grabbing. It’s not flashy, but it gets the job done. Just be prepared to customize your toolbar layout and maybe label the buttons yourself.

Would I recommend it? Yes, especially for power users who hate digging through menus. Beginners might find it unnecessary.

How to Install the SketchUp BZ Toolbar

Because the BZ Toolbar is a legacy plugin (originally .RB files), the installation method differs slightly from the modern SketchUp Extension Warehouse (where you click "Install").

Step-by-Step Installation (SketchUp 2017 and later):

  1. Download the RBZ file: Find the official BZ_Scale or BZ_Tools RBZ file. (Note: Always download from trusted forums like SketchUcation or the original developer’s site to avoid malware).
  2. Open SketchUp: Go to Window > Extension Manager.
  3. Install Extension: Click the Install Extension button (the wrench icon).
  4. Locate the file: Find your downloaded .rbz file and open it.
  5. Activate Toolbar: Once installed, right-click on your toolbar area (top of the screen). Look for "BZ_Scale" or "BZ_Tools" in the context menu. Check the box to make it appear.

Important Note: The original BZ Toolbar was written for SketchUp 8 through 2015. Many users report it works perfectly up to SketchUp 2023 and 2024, but always check for compatibility updates on the forums.

3. If “BZ” Refers to a Custom or Legacy Script

Some older SketchUp (pre-2017) Ruby scripts used two-letter prefixes like BZ_.
These were often:

  • Personal or company-internal tools
  • Not maintained for SketchUp 2020+
  • Incompatible with newer Ruby versions

Recommendation:
If you have a .rb file named bz_toolbar.rb, open it in a text editor to check the author/description.

Installation

  1. Download the BZ Toolbar RBZ file from a trusted source (SketchUcation or Extension Warehouse if available).
  2. In SketchUp: Window → Extension Manager → Install Extension → select the .rbz file.
  3. Restart SketchUp if prompted.
  4. Enable the toolbar: View → Toolbars (Windows) or SketchUp → Preferences → Extensions (Mac) and check “BZ Toolbar”.

Workflow B: Furniture Design

  1. Model a drawer component.
  2. Use Set Component Axes to set the axis to the bottom back corner (for snapping).
  3. Copy the drawer four times vertically.
  4. Need a larger handle? Use Replace Component to change the handle on all four drawers simultaneously.
  5. Run the Cleanup tool to purge the history of the handle geometry, keeping the file lean.

4. Cleanup Tools (Purge & Fix)

Icon: A broom or a band-aid (depending on version). The Problem: Your file is 200MB. You have unused materials, layers, and "hollow" components. The Solution: BZ includes a deep purge that removes unused items inside nested components. The standard SketchUp "Purge Unused" only scratches the surface. BZ goes deep, often reducing file sizes by 40%.
