Zorro Plugin Sketchup 2021
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.
Let’s look at why you should still download this legacy plugin, how to install it in 2021, and where it fails.
Why did SketchUp 2021 users love it?
- Speed: It processes complex meshes in seconds.
- Laser Cutting Prep: Architects and hobbyists use it to flatten 3D shapes into 2D interlocking slices (Contour Modeling).
- Destructive vs. Non-Destructive: For 2021 workflows, Zorro provided a destructive alternative to Live Components.

This report provides a comprehensive overview of , a popular and long-standing plugin for SketchUp 2021 designed to simplify complex slicing and sectioning tasks. Executive Summary Zorro2 is a free extension developed by mind.sight.studios
(originally by Dale Martens) that allows users to "slice" through 3D models with a single line. Since its inception in 2009, it has become a staple for SketchUp users who need to create clean cuts for section views, rendering, or complex geometric detailing. SketchUp Extension Warehouse Core Functionality & Key Features
The plugin's primary purpose is to create new edges and split faces along a user-defined line, effectively "swinging a sword" through the model. Description Simple Slicing
Click two points to draw a line; Zorro2 slices all visible geometry along that path. Nested Groups/Components
while slicing to cut through nested groups and components, a task that is normally tedious in native SketchUp. Section Plane Slicing Right-click a Section Plane
and choose "Slice Model at Section." This permanently removes geometry behind the plane, which is essential for certain rendering engines that cannot process native SketchUp section cuts. Precision Cutting
Works with inferencing and can be used in parallel projection views for architectural accuracy. Compatibility and Installation for SketchUp 2021

If you need help installing Zorro in SketchUp 2021 or want a step-by-step example of slicing a model, just let me know.
The Zorro2 plugin remains one of the most essential free extensions for SketchUp 2021 users who need a more powerful way to manipulate and section their geometry than native tools allow. While SketchUp includes section planes by default, they are merely visual representations; Zorro2 differentiates itself by performing literal, destructive slices that physically divide or trim your model. Key Features of Zorro2
Zorro2 is designed with a singular, effective goal: to create new edges wherever you "swing your sword". Title: The Blade is Back: A Deep Dive
Manual Slicing: You can click two points to draw a line, and the plugin will slice through all visible geometry along that path.
Nested Group Support: By holding the CTRL key while slicing, the tool can cut through nested groups and components, which typically resist standard modeling tools.
Section Plane Slicing: This is its most powerful feature. You can right-click an existing SketchUp section plane and select "Slice Model at Section" to permanently delete everything behind that plane.
Precision Control: It is highly recommended to use the tool in Parallel Projection mode from standard views (Top, Front, etc.) to ensure perfectly straight cuts. Why Use Zorro2 in SketchUp 2021?
Rendering Sections: Many external rendering engines like V-Ray or Kerkythea cannot always interpret SketchUp’s native visual section planes. Zorro2 physically removes the unwanted geometry, allowing these programs to render the interior of a model easily.
Quantity Surveying: It is frequently used to break out specific areas of a model to perform more accurate material takeoffs and quantity surveying.
Cleaning Geometry: It "cuts the fat" by chopping off messy edges or unnecessary geometry that doesn't need to be part of the final component. How to Install Zorro2 on SketchUp 2021
Since Zorro2 is a standard .rbz file, installation is straightforward through the native Extension Manager. Sections Via Zorro 2 | Visualizing Architecture
plugin for SketchUp 2021 is a free utility designed to slice through complex 3D models with ease. It is primarily used to create sections or divide geometry into smaller pieces for rendering, 3D printing, or quantity surveying. Core Features & Functionality Precision Slicing
: Define two points to create a straight "cut" line through all visible geometry. Nested Geometry Cutting : By holding the
key while slicing, you can cut through nested groups and components simultaneously. Section Plane Slicing
: You can right-click a standard SketchUp Section Plane and select " Slice model at section
." This is a destructive process that permanently removes geometry on one side of the plane. Rendering Sections
: It allows you to render section cuts in external programs that do not natively support SketchUp's section planes. How to Use Zorro2 : Choose the Zorro tool from the menu or the toolbar. Click once to start the cut. Click a second time to complete the path. : Turn off Perspective
(Camera > Parallel Projection) and use a standard view (Top, Front, etc.) for the most accurate straight cuts. Section Cuts : Place a Section Plane, right-click it, and select " Slice Model at Section " to delete everything behind that plane. Compatibility & Installation for SketchUp 2021 Speed: It processes complex meshes in seconds
The Zorro2 plugin remains a staple tool for SketchUp 2021 users who need to slice through geometry cleanly, especially when native tools fall short for non-solid objects. Core Functionality
Zorro2 is designed to "cut" through your model as if using a sword. Unlike SketchUp’s native section tools which only hide geometry, Zorro actually splits the geometry into separate pieces.
Line Slicing: You can slice by clicking two points to draw a cutting line across your view.
Nested Cutting: By holding the CTRL key while slicing, the plugin can cut through nested groups and components, which is a major time-saver for complex models.
Section Plane Slicing: A standout feature is the "Slice Model at Section" option found in the right-click context menu of any section plane. This deletes everything on one side of the plane, physically trimming the model. Best Practices for SketchUp 2021
To get the most out of Zorro2 in newer versions like 2021, consider these workflow tips:
Perspective Mode: For the most accurate "straight" cuts, turn off perspective and use a default standard view (like Top or Front).
Pairing with FixIt: Zorro2 creates edges but does not automatically "cap" or create faces on the resulting holes. Many users pair it with extensions like FixIt 101 to automatically generate missing faces and clean up stray edges after a cut.
Solid Tools Alternative: While Zorro2 works on any geometry, if you are working strictly with "Solid" groups, native Solid Tools or Eneroth Solid Tools might be more efficient for simple subtractions. Installation
You can find and install Zorro2 via the SketchUp Extension Warehouse or the SketchUcation PluginStore.

Is Zorro Safe for SketchUp 2021 in 2025?
As of 2025, yes, it is safe, but treat it as "abandonware." There will be no updates. For mission-critical commercial work, consider purchasing a modern alternative like Slicer 5.0. For hobbyists, students, or one-off projects, Zorro on SketchUp 2021 is a fantastic, free 2D/3D slicing solution.
4. Interoperability and pipeline thinking
In modern studios, SketchUp is rarely the final stop. Plugins that prioritize clean exports, consistent naming, and compatibility with downstream tools (renderers, BIM/LOD workflows, CNC/export formats) increase long-term value. Zorro’s place in a pipeline depends on whether it complements established exchange formats and produces predictable geometry that downstream tools can consume.
1. Executive Summary
The Zorro plugin is a utility extension for Trimble SketchUp designed to bridge the gap between temporary visual sectioning and permanent geometry modification. In SketchUp 2021, while the native "Section Planes" feature allows users to view cross-sections of a model, it does not natively allow users to delete the geometry behind the cut or separate the front from the back efficiently. Zorro solves this by automating the process of intersecting geometry and deleting the hidden portions, effectively "slicing" a model permanently.
