Can I lock an object so it cannot be moved or edited in SketchUp?
Short Answer
Yes — in SketchUp, you can effectively stop an object from being moved or edited by making it a group or component and then using Lock from the right-click context menu. This is the most common professional method to protect selected geometry during modeling. Limitation: locked objects can still be unlocked manually at any time.
What You Need to Know Before
Warning: Locking in SketchUp prevents selection and editing in normal workflow, but it is not password protection or true file security. A common failure is thinking a locked object is permanently protected when any user can simply right-click and unlock it.
How to Lock an Object in SketchUp
Command: Lock
Shortcut: None by default
Quick Steps:
- Select the object, then make sure it is a Group or Component first if needed using right-click > Make Group or Make Component.
- Right-click the selected object in the modeling window.
- Click Lock from the context menu. The object will remain visible but cannot be moved or edited until unlocked.
Variables & Settings
Key Setting: Outliner panel lock status
- In the Outliner, locked groups and components show their locked state and can be managed more reliably in complex models. This is useful when selection in the main view is difficult or when multiple nested objects are involved.
Why it Fails
- Cause 1 (Geometry): Raw geometry is not isolated, so edges and faces may still be edited unless they are first grouped or made into a component.
- Cause 2 (layers/Locks): If Tag visibility changes or the object is inside another editable container, users may think the lock failed when they are actually editing different geometry.
- Cause 3 (Command/Logic): Lock only blocks normal selection and editing; it does not stop users from unlocking the object or modifying copied instances of the same component.
Quick Fix & Best Practice
- Quick Fix: If the object still edits unexpectedly, select it and use right-click > Make Group, then right-click > Lock again.
- Manager’s Verdict: Use Lock for protecting reference geometry, furniture layouts, imported CAD backgrounds, and approved model elements, but do not treat it as secure access control in shared SketchUp files.
FAQ
Can I lock raw edges and faces in SketchUp?
No, the best practice is to first turn them into a group or component.
How do I unlock a locked object in SketchUp?
