Troubleshooting: Issues with Layer Purging
Unable to Purge Layers
If you’re unable to purge certain layers, follow these steps:
1. Input the command **LAYDEL** directly into the command line.
2. You will be prompted to choose a method. Select **Name** or type **N**.
3. From the list, select the layer you wish to delete and press **OK**.
Purge Unused Layers
For users looking to clear out unused layers:
1. Type **LAYDEL** in the command line and hit Enter.
2. You can select the objects on the layers you want to delete, or use the **Name** option to pick layers directly from the Delete Layers dialog.
3. Utilize the **Shift** or **Ctrl** keys to select multiple layers as needed.
Identifying and Managing Hidden Layers
To make hidden layers visible:
1. Go to the **Home** tab and find the **Layers** panel; click on **Layer Properties**.
2. Choose the layers that need to be activated or deactivated.
3. Adjust the visibility by toggling the icons in the **On** column.
Removing Non-Purgeable Blocks
If you need to purge blocks that aren’t initially marked for removal:
1. Expand the **Blocks** section by double-clicking it.
2. Select the blocks that you aim to purge.
3. If an item isn’t visible for purging, click on **Find Non-Purgeable Items** to identify them.
The Role of Layer Locking
Locking a layer prevents any alterations to the objects within. Locked objects appear faded, and a lock icon is shown when hovered over. This feature minimizes accidental changes in your drawings.
Preventing Layers from Printing
If it’s necessary to stop a layer’s objects from being printed:
1. Highlight the layer in the Layers panel.
2. Access the Layer Options through the panel menu.
3. Uncheck the **Print Layer** option and click **OK** to apply your changes.
