Zorro2 is a popular, free Ruby extension for SketchUp, developed by Whaat (MindSight Studios), designed specifically for advanced slicing of 3D geometry. It is widely used for creating 3D sections, cutting through complex models, and preparing geometry for rendering.
While the "Zorro2" plugin was originally released in 2009, its updated versions remain functional in SketchUp 2021 through the SketchUp Extension Warehouse or SketchUcation PluginStore. Key Features of Zorro2
"Swing Your Sword": Click two points to slice through raw geometry along the line you draw.
Cut Nested Components/Groups: Holding the Ctrl key while slicing allows the cut to pass through nested groups and components.
Slice at Section Plan: A powerful feature that allows you to right-click a SketchUp Section Plane and select 'Slice Model at Section'. This deletes all geometry behind the plane.
Optimized for Rendering: Ideal for creating 3D section models to be rendered in external programs.
Parallel Projection Support: Allows for precise, straight cuts from standard views (Front, Top, Side). Installation for SketchUp 2021
Download: Obtain the latest .rbz file from the Extension Warehouse or SketchUcation.
Install: In SketchUp 2021, go to Window > Extension Manager.
Load: Click "Install Extension" and select the downloaded file. Best Practices & Workflow
Save Backup: The "Slice Model at Section" command is destructive (it deletes geometry), so save your model before using it.
Use Parallel Projection: Turn off Perspective Mode for precise, predictable cuts.
Group/Component Slicing: To cut through nested items, remember to hold CTRL.
Fixing Holes: Use plugins like SectionCutFace to patch the "holes" created by Zorro to create solid, rendered sections.

Title: The Blade is Back: A Deep Dive into the Zorro Plugin for SketchUp 2021
Subtitle: Why this "ancient" split-tool remains the king of non-destructive cutting for legacy users.
If you have been using SketchUp for more than a decade, the name Zorro needs no introduction. For newcomers: Zorro was the original "Slice and Dice" tool. Long before Solid Tools became stable, and before extensions like Slice or Eneroth Splitter dominated the scene, there was Zorro.
But here is the controversy: The original Zorro plugin was abandoned around SketchUp 2017. However, a revived version—often called Zorro 2 or the "Stable Build" —works flawlessly for many users on SketchUp 2021. zorro plugin sketchup 2021
Let’s look at why you should still download this legacy plugin, how to install it in 2021, and where it fails.
Plugins thrive when they engage user feedback loops. A responsive update cadence, clear documentation, tutorials, and real-world example files turn an add-on from a novelty into an indispensable tool. If Zorro fosters a community—templates, shared recipes, best practices—it becomes a vector for collective problem-solving rather than a solitary utility.
For SketchUp 2021 users who need to section, flatten, or cut geometry without switching to a dedicated CAD package, Zorro is an essential free plugin. It’s stable, lightweight, and deeply integrated into the SketchUp workflow. Whether you’re preparing a model for 3D printing, laser cutting, or simply analyzing cross‑sections, Zorro delivers surgical precision with just a few clicks.
Download it today from the SketchUcation Plugin Store – and always remember to check that TIG’s latest version explicitly supports SketchUp 2021 (v21.x).
plugin for SketchUp 2021 is a powerful slicing tool that physicalizes section cuts by literally "cutting" through your model's geometry. Unlike SketchUp’s native section planes, which are merely visual effects, Zorro creates permanent new edges and can delete parts of the model to reveal interiors for rendering or quantity surveying. Key Features Manual Slicing
: Draw a line by clicking two points to slice through all visible geometry. Deep Cutting : Hold the
key while slicing to cut through nested groups and components. Slice at Section
: Right-click any active SketchUp Section Plane and select "Slice model at section" to permanently trim away everything behind that plane. Rendering-Ready
: Because it performs a physical cut, it allows 3D sections to be visible in external rendering engines that don't natively support SketchUp’s visual section planes.

Technical Review: Zorro2 Plugin for SketchUp 2021 The Zorro2 plugin remains one of the most enduring and essential utilities for SketchUp users. Originally developed by Whaat (Dale Martens), its primary function is to "slice" through geometry, effectively acting as a digital sword that creates clean cuts across a model. Core Functionality
Zorro2 provides a streamlined approach to model modification that the native SketchUp toolset does not offer directly: Title: The Blade is Back: A Deep Dive
The "Sword" Slice: By clicking two points, users can draw a line that slices through all visible, non-grouped geometry in its path.
Nested Slicing: A critical feature is the ability to cut through nested groups and components. By holding the CTRL key while slicing, the plugin penetrates deep into the model hierarchy to divide complex assemblies.
Section Plane Integration: One of its most powerful workflows involves right-clicking a Section Plane and selecting "Slice Model at Section." This permanently trims the model at that plane, allowing for clean exports to external rendering engines that may not natively support SketchUp's section cuts. Performance in SketchUp 2021
While the plugin has not seen a major version update in several years, it remains highly compatible with SketchUp 2021.
Installation: The plugin is typically distributed as an .rbz file via the SketchUp Extension Warehouse or the SketchUcation PluginStore.
Stability: Users in the 2021 environment report that the "Slice at Section" tool is stable, though it is always recommended to save a backup of the model before performing destructive "Slice Model" operations. Comparative Utility
In the modern SketchUp ecosystem, some of Zorro2's original rendering-prep functions have been superseded by advanced engines (like V-Ray or Enscape) that handle live section cuts. However, it remains the gold standard for geometry management, specifically for:
Iterative Design: Quickly splitting a massing model to test different facade treatments.
Model Cleanup: Removing large sections of unnecessary geometry to reduce file size.
3D Printing Prep: Slicing large models into printable parts that fit on a specific build plate. Conclusion
For SketchUp 2021 users, Zorro2 is a "legacy" plugin that still performs a modern, vital role. Its simplicity—providing a single, sharp tool for a specific task—makes it a staple for architectural and mechanical modeling workflows.
Let's assume you have a complex terrain mesh or a carved wooden chair leg.
SketchUp’s strength is accessible geometric manipulation; plugins must preserve that ethos. Zorro’s design decisions—how it surfaces options, how it previews changes, and how it integrates with native selection and groups/components—determine whether it feels like an elegant extension or a heavyweight add-on. Ideally, functionality such as snapping, constraint-aware operations, or targeted exports should be discoverable without steep learning curves.
