Are you looking to cut a section in SketchUp for free? Look no further, as we have got you covered!

In this tutorial, we will guide you through the steps to cut a section in SketchUp using the free version of the software. So let’s get started!

Step 1: Open SketchUp

If you haven’t installed SketchUp yet, head over to the official website and download the free version. Once you have successfully installed it, launch SketchUp on your computer.

Step 2: Create Your Model

In order to cut a section in SketchUp, you first need to create a model or open an existing one. Use the various drawing and modeling tools available in SketchUp to design your model according to your requirements.


  • Use Guides: To ensure accuracy and precision, utilize guides to align your elements properly.
  • Create Components: If your model consists of repetitive elements, consider creating components for easy editing and duplication.
  • Group Elements: Grouping related elements helps in organizing and manipulating them collectively.

Step 3: Activate Section Plane

To cut a section in SketchUp, we will use the Section Plane tool. Locate this tool in the Tools menu or activate it by clicking on its icon from the toolbar. Once activated, move your cursor over the desired location where you want to place the section plane.


  • Rotate Section Plane: To rotate the section plane along an axis, simply click and drag its circular handle.
  • Move Section Plane: To move the section plane to a different location, click and drag its rectangular handle.

Step 4: Position the Section Plane

With the section plane activated, position it perpendicular to the desired section you want to cut through your model. You can adjust the position by clicking and dragging the rectangular handle of the section plane.


  • Resize Section Plane: To resize the section plane, click and drag any of its corner handles.
  • Invert Section: To invert the section, right-click on the section plane and select “Flip Along”. Then choose the desired axis to flip it.

Step 5: Cut Your Section

Now that you have positioned your section plane, it’s time to cut through your model. Simply click on one of the sides of the section plane to activate it. SketchUp will automatically hide everything that is behind or below the section plane, giving you a clear view of your cut section.


  • Show Hidden Geometry: If you want to see hidden geometry within your cut section, go to View > Hidden Geometry from the menu bar.
  • Edit Your Model: While in a cut section view, you can still edit your model. Any changes made will be reflected both inside and outside of the cut area.
