Why Is My Linetype Not Changing in AutoCAD?

Are you facing the frustrating issue of your linetype not changing in AutoCAD? Don’t worry, you’re not alone!

This is a common problem that many AutoCAD users encounter. In this article, we will explore the possible reasons behind this issue and provide solutions to help you resolve it.

Possible Reasons for Linetype Not Changing

If your linetype is not changing as expected, there could be several reasons behind it. Let’s take a look at some of the most common causes:

1. Incorrect Layer Settings

The linetype of an object in AutoCAD is determined by its layer settings. If the layer that the object is on has a specific linetype assigned to it, then all objects on that layer will inherit that linetype. Therefore, if your linetype is not changing, double-check the layer settings to ensure that they are correctly configured.

2. ByLayer Linetype Assignment

AutoCAD allows you to assign linetypes either explicitly or by layer. If an object has its linetype set to “ByLayer,” it will inherit the linetype of the layer it’s on. Make sure that your object’s linetype is set explicitly and not set to “ByLayer,” as this can cause unexpected results.

3. Invalid Linetypes

If you are trying to change the linetype to a custom or non-standard linetype, ensure that the linetype definition is valid and loaded into your drawing. AutoCAD provides several default linetypes, but if you are using a custom one, make sure it is available in your drawing or loaded from an external file.

Solutions for Changing Linetypes

Now that we have covered some possible causes for your linetype not changing, let’s explore some solutions to help you resolve this issue:

1. Check Layer Settings

Start by verifying the layer settings for the object that is not changing its linetype. Open the Layer Properties Manager by typing “LA” in the command line or selecting it from the Ribbon.

Ensure that the layer has the correct linetype assigned and that it is not set to “ByLayer. “

2. Assign Linetype Explicitly

If your linetype is set to “ByLayer,” change it to a specific linetype. Select the object and open its properties by typing “PROPERTIES” in the command line or using the Properties palette. In the Properties palette, locate the Linetype property and select a specific linetype from the drop-down menu. Load Custom Linetypes

If you are using custom linetypes and they are not available in your drawing, you need to load them before you can use them. Use the LINETYPE command or access the Linetype Manager from the Ribbon to load the required linetypes into your drawing.


In conclusion, if your linetype is not changing in AutoCAD, it can be due to incorrect layer settings, “ByLayer” linetype assignment, or missing custom linetypes. By checking and adjusting these settings as necessary, you should be able to resolve this issue and have full control over your linetypes in AutoCAD.

Remember to double-check your layer settings, assign linetypes explicitly when needed, and ensure that any custom or non-standard linetypes are loaded into your drawing.

With these solutions at hand, you can overcome any hurdles you encounter with changing linetypes in AutoCAD!
