How Do You Split Objects in SketchUp?

SketchUp is a powerful 3D modeling software that allows you to create complex designs and models. One of the essential tasks in SketchUp is splitting objects.

Whether you want to separate a group of connected faces or divide a solid into multiple parts, SketchUp provides several tools to help you achieve this. In this tutorial, we will explore different techniques for splitting objects in SketchUp.

The Split Tool

The Split Tool is one of the most straightforward methods for dividing objects in SketchUp. It allows you to draw a line or use an existing edge to cut through surfaces and solids.

To use the Split Tool:

  1. Select the object you want to split.
  2. Activate the Split Tool by clicking on its icon in the toolbar or navigating to Tools > Split.
  3. Click on an existing edge or draw a new line across the object where you want it to split.
  4. The object will be divided into two separate parts along the line or edge you selected.

The Intersect Faces Tool

If you have intersecting surfaces that need splitting, the Intersect Faces Tool can be very helpful. It allows you to create intersections between multiple objects and then split them at those intersections.

To use the Intersect Faces Tool:

  1. Select all the objects that intersect with each other and need splitting.
  2. Right-click on one of the selected objects and choose Intersect Faces > With Selection from the context menu.
    • This action creates intersection edges at all the points where objects intersect.
  3. With the intersections created, you can now use the Split Tool or the Eraser Tool to remove unwanted parts and split the objects as desired.

The Solid Tools

If you are working with solid objects in SketchUp, the Solid Tools can provide efficient ways to split them. These tools include Union, Subtract, Intersect, and Trim. For splitting purposes, we will focus on the Subtract tool.

To use the Subtract Tool:

  1. Create two solid objects that overlap or intersect with each other.
  2. Select both objects.
  3. Activate the Solid Tools by clicking on their icon in the toolbar or navigating to Tools > Solid Tools.
  4. Choose Subtract from the Solid Tools menu.
    • This action subtracts one object from another, resulting in a split where they intersected.

The Split by Plane Plugin

If you need more advanced splitting options, plugins can extend SketchUp’s capabilities. The Split by Plane plugin is a popular choice for creating section cuts and splitting objects based on custom planes or profiles.

To install and use the Split by Plane plugin:

  1. Download and install the Split by Plane plugin from a trusted source.
  2. Restart SketchUp if necessary.
  3. Select the object you want to split.
  4. Navigate to Plugins > Split by Plane > Create Section Cut.
    • This action enables you to draw a section cut line or import a profile to define the splitting plane.
  5. Once the section cut or profile is created, you can split the object by right-clicking on the section and choosing Split Object from the context menu.

Conclusion

Splitting objects in SketchUp is a crucial skill for precise modeling and design. Whether you use the Split Tool, Intersect Faces Tool, Solid Tools, or plugins like Split by Plane, understanding these techniques will greatly enhance your workflow and allow you to create more complex and detailed models.
