How Do I Lock a Selection in SketchUp?

SketchUp is a powerful tool that allows you to create 3D models and designs. However, when working on complex projects, you may find yourself needing to lock certain parts of your model to prevent accidental modifications. In this tutorial, we will explore how to lock a selection in SketchUp using different methods.

Method 1: Using the Selection Lock feature

If you want to lock a specific selection in SketchUp, you can use the built-in Selection Lock feature. Here’s how:

  1. Select the entities or objects that you want to lock.
  2. Right-click on the selection and choose “Lock” from the context menu.

This will lock your selection, preventing any accidental modifications or movements.

Method 2: Using Layers

If you prefer a more organized approach, you can also use layers to lock specific parts of your model. Follow these steps:

  1. Create a new layer by clicking on the “Layers” icon in the toolbar or navigating to “Window > Layers”.
  2. Name your layer something descriptive like “Locked Objects”.
  3. Select the entities or objects that you want to lock.
  4. In the “Layers” panel, assign your selected entities or objects to the newly created layer by clicking on the layer’s name.
  5. To lock/unlock your selection, simply click on the empty box next to the layer’s name in the “Visible” column.

Using layers provides greater flexibility as you can easily toggle the visibility of locked objects.

Method 3: Using Groups and Components

In SketchUp, creating groups or components is another effective way to lock parts of your model.

  • Right-click on the selection and choose “Make Group” or “Make Component”.
  • Making a group or component will isolate your selection, making it easier to handle and manipulate without affecting other parts of your model.


    • Naming: It’s a good practice to provide descriptive names for your groups, components, and layers. This helps in organizing and managing your model efficiently.
    • Hierarchy: If you need to lock multiple selections, consider using nested groups or components. This allows you to control the locked objects at different levels.
    • Shortcut Key: You can use the keyboard shortcut “L” as a quick way to access the Selection Lock feature in SketchUp.

    Congratulations! Now you know how to lock a selection in SketchUp using different methods.

    Whether it’s using the built-in Selection Lock feature, utilizing layers, or creating groups/components, you have the power to protect specific parts of your models from accidental modifications. Happy modeling!
