SketchUp 2021 may no longer be the "latest version" (as of 2025, we are on 2024/2025), but it remains a workhorse for professionals who avoid subscription models. The Zorro plugin is the samurai sword in the carpenter's toolbox.
Mastering Zorro cuts your modeling time by 70% when preparing files for CNC, laser cutters, or 3D printers. It turns a visually impressive 3D model into a physically manufacturable product.
Final Checklist for Success:
Grab your sword, fire up SketchUp 2021, and start slicing your way to better design.
Call to Action: Have you tried Zorro with SketchUp 2021’s "Scan & Solve" or "Solid Tools"? Share your workflow tips in the comments below or check our forum for custom Ruby scripts that extend Zorro’s slicing ability!
Slice Through Your Design: Master the Zorro Plugin for SketchUp 2021
Have you ever needed to split a complex SketchUp model in half, but found the standard section planes lacking because they don't actually modify the geometry? Enter Zorro2, a legendary free plugin that has been "swinging its sword" through 3D models for over a decade.
Whether you're creating a detailed section for a quantity survey or preparing a model for a specific rendering style, Zorro remains one of the most efficient tools in an architect's arsenal. What is the Zorro Plugin?
The Zorro plugin (specifically Zorro2) is a surgical tool for SketchUp. While SketchUp’s built-in Section Planes only hide geometry, Zorro actually slices through it, creating new edges and faces exactly where you specify. Key Features
Slice Everything: Cut through nested groups and components by holding the CTRL key.
Section Plane Integration: Right-click any section plane and choose "Slice Model at Section" to delete everything on the "hidden" side of the cut. zorro plugin sketchup 2021
Precision Cutting: Works perfectly with inferencing and parallel projection views for dead-accurate splits. How to Use Zorro in SketchUp 2021
Using Zorro is straightforward, but for the best results in SketchUp 2021, follow these pro tips:
Select the Tool: Click the Zorro icon (the sword) in your toolbar.
Draw Your Cut: Click two points to define a line. Any visible, ungrouped geometry along that line will be sliced.
Pro Tip - Go Flat: To ensure a perfectly vertical or horizontal cut, switch to a Top or Front view and turn off Perspective (Camera > Parallel Projection) before slicing.
The "Nuclear" Option: If you want to permanently remove everything behind a section plane, create a Section Plane, right-click it, and select Slice Model at Section. Warning: Always save a backup before doing this, as it deletes geometry! Installation Guide for 2021 Users
Since Zorro is an older (but still functional) plugin, you might need to install it manually:
Download: Get the .rbz file from the SketchUp Extension Warehouse or SketchUcation.
Install: In SketchUp 2021, go to Window > Extension Manager, click Install Extension, and select your downloaded file.
Activate: If the toolbar doesn't appear, right-click any empty space on your top toolbar and ensure Zorro2 is checked. Why Still Use Zorro in 2021? SketchUp 2021 may no longer be the "latest
Even though SketchUp 2021 introduced better visibility controls for hidden geometry, it still doesn't offer a native "destructive" slice tool. If you need to export half a house to another program or physically separate two parts of a model for 3D printing or quantity takeoffs, Zorro is still the fastest way to get the job done.
Do you have a favorite SketchUp plugin that has stood the test of time? Let us know in the comments below!
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".
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. Grab your sword, fire up SketchUp 2021, and
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
Developed by Mike Lucey of MindSight Studios, Zorro is a simple but powerful extension that performs a single task: it cuts a SketchUp group or component along a plane (or multiple planes) and separates the pieces.
The "Zorro" effect comes from its ability to leave a zig-zag cut pattern, but its primary function is slicing objects into horizontal or vertical sections. It is particularly famous for:
The Zorro plugin is not a rendering engine or a texture tool. It is a geometry manipulation extension. At its core, it allows you to slice any group or component with a line, plane, or series of lines instantly.
Unlike SketchUp’s native "Section Plane" tool, which only hides geometry visually, Zorro actually cuts and divides the geometry permanently. When you run Zorro, you draw a line across your model, and the plugin splits every edge and face along that infinite line.
Your single group is now two distinct groups (or exploded geometry) precisely cut along your line.
Solution: Unlike older versions, SketchUp 2021 is aggressive about hiding incompatible toolbars. Manually load the script: Window > Ruby Console > Type load "zorro2/zorro_loader.rb" > Press Enter.
With the release of SketchUp 2022, Trimble introduced an upgraded Solid Tools set that allows for boolean operations without destroying the original objects. However, for SketchUp 2021 users, Zorro often remains superior to the native Solid Tools for one reason: Topology preservation.
The native Solid Tools in 2021 can sometimes merge coplanar faces or erase soft/smooth edges on curved surfaces during a cut. Zorro, being a simple intersection script, tends to preserve the existing shading and smoothing of the model more accurately.
