How Do You Cut a 3D Model in SketchUp?

Creating 3D models in SketchUp is an exciting process that allows you to bring your imagination to life. However, there may be instances where you need to cut a 3D model to modify or customize it further.

In this tutorial, we will explore different methods to cut a 3D model in SketchUp and achieve the desired results.

Method 1: Using the Intersect Faces Tool

The Intersect Faces tool in SketchUp is an excellent way to cut through a 3D model. Follow the steps below to use this tool effectively:

  1. Select the cutting object: Start by creating a new geometry or using an existing one as your cutting object. This can be a simple rectangular shape or any other shape that suits your needs.
  2. Position the cutting object: Move and position the cutting object exactly where you want to make the cut on your 3D model.
  3. Select both objects: Click on the Select tool from the toolbar and select both the cutting object and the 3D model you want to cut.
  4. Apply Intersect Faces: With both objects selected, go to Edit > Intersect Faces > With Selection.

    This action will create new faces at the intersection points of both objects.

  5. Clean up unwanted faces: After applying the Intersect Faces tool, you may find extra faces that were created during the process. Simply delete these unwanted faces using the Erase tool.

Method 2: Using Section Planes

Another powerful method for cutting a 3D model in SketchUp is by using Section Planes. This method allows you to create a “slice” through your model, revealing internal details or creating sections for construction purposes. Follow the steps below to use Section Planes effectively:

  1. Activate the Section Plane tool: Click on the Section Plane tool from the toolbar. It looks like a small plane with a dashed line.
  2. Create a section cut: Position your cursor where you want to make the cut and click once to place the first end of the section plane.

    Move your cursor to create the desired length and click again to complete the section cut.

  3. Adjust section properties: After creating a section plane, you can adjust its properties like color, visibility, and thickness by right-clicking on the section plane and selecting “Entity Info”. Here you can customize it according to your preferences.
  4. Explore your cut: Once you have created a section cut, you can navigate through it by activating the Move tool and clicking on any part of the section plane. This will allow you to explore your model from different perspectives.

Method 3: Using Plugins

SketchUp allows users to enhance its functionality by installing various plugins. Some plugins offer advanced cutting options that can simplify complex cutting tasks. Here are two popular plugins that can assist in cutting 3D models:

  • Solid Inspector²: This plugin helps identify any issues with your model’s geometry, including potential problems when cutting or intersecting objects.
  • Fredo6’s Joint Push/Pull: This plugin offers powerful push/pull capabilities that enable you to create intricate cuts and transformations on 3D models.

To use plugins in SketchUp, you need to download them from the official SketchUp Extension Warehouse or other trusted plugin sources. Once installed, the plugins will appear in the appropriate menus or toolbars for easy access.

In conclusion, cutting a 3D model in SketchUp is a straightforward process that can be achieved using various methods. Whether you choose to use the Intersect Faces tool, Section Planes, or plugins, it’s essential to experiment and find the method that suits your specific needs.

So go ahead and unleash your creativity by cutting and customizing your 3D models in SketchUp!
