Rhino 3D Cutting Tools Explained. How to use Trim, Split, SplitFace, Wirecut, BooleanDifference etc.
Cutting and splitting geometry in Rhino doesn’t have to be confusing. In this video, I walk you through the essential cutting tools in Rhino step by step — so you’ll know exactly when and how to use each one.
We’ll cover:
Trim – versatile tool for curves, surfaces, and solids
Wire Cut – the best way to cut clean openings like windows and doors
Split & Split Face – precise control for editing surfaces and geometry
Boolean Operations – using geometry to cut and subtract solids
Section & Contour – great for visualization, massing, and fabrication prep
Whether you’re just starting with Rhino or want to sharpen your modeling workflow, this guide breaks down the cutting process in simple terms with practical examples.
