Create a native SketchUp and position it exactly where you want to cut. Right-click on the active Section Plane. From the context menu, select Slice Model at Section .
In standard SketchUp 2021, if you insert a Section Plane, the geometry behind that plane is visually hidden inside the viewport. However, external rendering engines like often struggle with native SketchUp sections. They will either render the entire uncut object or create strange lighting artifacts because the geometry still physically exists in the 3D space.
: Works flawlessly with default top, front, or side views to create perfectly straight cuts. How Zorro Resolves the "Rendering Section Cuts" Problem
While powerful, Zorro is not without its quirks, especially when running on newer engines like SketchUp 2021.
Visit the SketchUcation Plugin Store and search for Zorro2 . Download the .rbz file to your computer.
If you slice a component that has multiple copies (instances) in the model, Zorro will slice all instances of that component. If you only want to cut one, right-click it and select Make Unique before using Zorro.
Design a chair leg that intersects a seat. Use Zorro to cut the negative space from the seat, creating a perfect mortise and tenon joint via boolean logic.

Go to View > Toolbars , scroll down to find Zorro, and ensure the checkbox next to it is marked. Conclusion
Always group your objects before slicing. Zorro cuts inside groups beautifully, preventing loose geometry from sticking together after the cut.
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.
Cuts complex architectural assemblies cleanly in half to measure spatial volumes and isolate distinct zones. Key Features & Controls
: Many rendering engines struggle to "see" native SketchUp section planes. By using Zorro2 to physically slice the model at a section cut, you ensure your rendering software captures the interior details perfectly.
Stick with Zorro2 for simple cuts. Switch to S4U Slice for parametric modeling.
Wait a few seconds. Zorro will physically cut and separate all geometry passing through that plane. Pro-Tips for Clean Modeling with Zorro2
Zorro alters physical geometry permanently. Always save a backup copy of your project before performing a major slice operation.
Breaking a large facade into smaller, manageable panels or creating expansion joints in concrete models. Cleaning Models:
: 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
