How to Change Layer Linetype in AutoCAD Quickly

To change a layer's linetype in AutoCAD, open the Layer Properties Manager, select the desired layer, and click the Linetype column to choose or load a new linetype. After selecting, click OK to apply the change to that layer.

Syntax

In AutoCAD, changing a layer's linetype involves these steps:

• Layer Properties Manager: The interface to manage layers.
• Select Layer: Choose the layer whose linetype you want to change.
• Linetype Column: Click here to open the linetype selection dialog.
• Load Linetype: If the desired linetype is not listed, load it from the standard linetype files.
• Apply: Confirm the selection to update the layer's linetype.

plaintext

1. Type LAYER or LA in the command line and press Enter.
2. In Layer Properties Manager, click the layer name.
3. Click the Linetype field for that layer.
4. Click Load if the linetype is not available.
5. Select the desired linetype and click OK.
6. Close Layer Properties Manager.

Example

This example shows how to change the linetype of the layer named Walls to Dashed:

plaintext

Command: LAYER
Layer Properties Manager opens.
Select layer: Walls
Click Linetype column next to Walls.
Click Load.
Select Dashed from the list.
Click OK.
Click OK again to apply.
Close Layer Properties Manager.

Output

The Walls layer now displays with the Dashed linetype in the drawing.

Common Pitfalls

Common mistakes when changing layer linetypes include:

• Not loading the desired linetype before selecting it, so it doesn't appear in the list.
• Forgetting to regenerate the drawing (REGEN command) to see the updated linetype.
• Changing the linetype of objects directly instead of the layer, causing inconsistent appearance.
• Using continuous linetype objects on layers with non-continuous linetypes, which may override layer settings.

plaintext

Wrong way:
- Select objects and change their linetype property instead of the layer's linetype.

Right way:
- Change the linetype in Layer Properties Manager for the whole layer.
- Use REGEN command to refresh the display.

Quick Reference

Step	Action
1	Open Layer Properties Manager (type LAYER or LA)
2	Select the layer to change
3	Click the Linetype column for that layer
4	Click Load to add new linetypes if needed
5	Choose desired linetype and click OK
6	Close Layer Properties Manager
7	Type REGEN to refresh the drawing display

Key Takeaways

Use Layer Properties Manager to change a layer's linetype for consistent drawing style.

Load new linetypes if they are not listed before applying them.

Always regenerate the drawing with REGEN to see linetype changes.

Avoid changing individual object linetypes when layer control is preferred.

Check that objects on the layer use ByLayer linetype property for correct display.
