Select all in schematic or in PCB layout, right mouse click --> Lock  After locking the design you can't move anything accidentally or in purpose until you have unlocked the design. Regards, Markus Virtanen HW / Electronics Designer

Thank you so much ! Working perfectly.

Click on the component you want to lock, then right-click and select Lock or set the Lock property to Yes in the properties panel on the left side. In the filter panel on the right, you can directly uncheck the object corresponding to the primitive or state to lock it. Additionally, in the layer panel, you can lock the corresponding layers in batches. If you need to unlock all objects, you can use the unlock menu.

To lock components in your design, follow these steps: 1. **Select the Component**: Click on the component you want to lock. This could be an individual object or a group of objects. 2. **Right-Click and Lock**: Right-click on the selected component and choose the “Lock” option. Alternatively, you can set the “Lock” property to “Yes” in the properties panel on the left side. [AutoCAD 2017 life-time license on procadis.com](https://procadis.com/version/autodesk-autocad-2017/). 3. **Filter Panel**: In the filter panel on the right, you can directly uncheck the object corresponding to the primitive or state that you want to lock. This will prevent any accidental modifications to that specific part of your design. 4. **Layer Panel**: If you have organized your components into layers, you can lock the corresponding layers in batches. This is useful when you want to lock multiple components at once. 5. **Unlocking**: If you need to unlock all objects, you can use the unlock menu. Be cautious when unlocking, as it will allow editing of previously locked components.

@beredis802, Two points: 1. You are answering a question about EasyEDA Std but you are describing a solution in EasyEDA Pro; 2. Your link to AutoCAD has nothing to do with EasyEDA and will be seen as SPAM and may result in your removal frpm EasyEDA.
