# How to lock and unlock objects

# How to lock and unlock objects
Locking prevents accidental edits while you arrange, duplicate, delete, or slice other models. You can lock individual objects, parts, all objects, or all objects on a plate.

## What locking does
A locked object is protected from normal object-list, context-menu, and toolbar editing actions.

Locked objects are skipped or blocked by actions such as:

- Select all
- Move, rotate, and scale
- Delete
- Duplicate and clone
- Auto-arrange
- Object and part setting edits
- Lay on face
- Smart rotate

The slicer also temporarily locks objects while slicing is in progress.

## Lock or unlock one object
1. Open **Objects**.
2. Find the object.
3. Click the lock icon on the object row.

The icon changes between locked and unlocked.

You can also right-click the object and choose **Lock** or **Unlock**.

## Lock or unlock a part
1. Open **Objects**.
2. Expand the parent object.
3. Find the part.
4. Click the lock icon on the part row.

Part locking is useful when you want to protect one modifier, text part, or model part while editing the rest of the object.

## Lock or unlock all objects on a plate
1. Open **Objects**.
2. Find the plate group.
3. Click the lock icon on the plate row.

This locks or unlocks the lockable objects currently on that plate.

## Lock or unlock all objects
Right-click an empty area of the slicer workspace and choose **Lock all** or **Unlock all**.

This is useful before making a precise change to one newly imported model, or when you want to prevent accidental edits across the whole scene.

## Why an object may still be locked
Some locks are temporary or system-controlled. For example, the Cloud Slicer locks objects while slicing or processing them.

If an object cannot be unlocked from the object list, wait for the current operation to finish and try again.
