How Do I Change Linetype in AutoCAD?

by

In AutoCAD, the linetype of an object determines the pattern and style of the line. By default, AutoCAD provides several linetypes such as continuous, dashed, dotted, and so on.

However, there may be instances where you need to change the linetype for a specific object or layer to suit your design requirements. In this tutorial, we will explore different methods to change linetypes in AutoCAD.

Method 1: Changing Linetype Using the Properties Palette

One of the simplest ways to change the linetype in AutoCAD is by using the Properties palette. Follow these steps:

  1. Select the object whose linetype you want to change.
  2. Right-click on the selected object and choose “Properties” from the context menu.
  3. The Properties palette will appear on your screen. Scroll down until you find “Linetype” under the “General” section.
  4. Click on the dropdown menu next to “Linetype” and select your desired linetype from the list.

Note: If you want to apply a different linetype to multiple objects at once, you can select all of them before accessing the Properties palette.

Method 2: Changing Linetypes Using Layers

Layers play a significant role in managing and organizing objects in AutoCAD. You can assign specific linetypes to layers so that any object drawn on that layer automatically inherits its linetype. Here’s how you can change linetypes using layers:

  1. Type “LA” in the command line and press Enter. This will open the Layer Properties Manager dialog box.
  2. In the Layer Properties Manager, locate and select the layer for which you want to change the linetype.
  3. In the “Linetype” column, click on the current linetype name and select a new linetype from the list.
  4. Click on “OK” to apply the changes.

Note: Changing the linetype of a layer will affect all objects on that layer.

Method 3: Creating Custom Linetypes

If the default linetypes in AutoCAD do not meet your requirements, you can create custom linetypes with unique patterns. Here’s how:

  1. Type “LT” in the command line and press Enter. This will open the Linetype Manager dialog box.
  2. Click on the “Load..” button and select a LIN file (linetype definition file) or create a new one by clicking on “New.”.
  3. In the Create or Edit Linetype dialog box, specify a name for your custom linetype.
  4. Under “Pattern”, define the pattern for your linetype using various characters such as dash (-), dot (.), space ( ), etc.
  5. Adjust other parameters like scale, offset, and description as per your requirements.
  6. Click on “OK” to save your custom linetype.

Note: Once you have created a custom linetype, you can use it by selecting it from the Linetype dropdown menu in either the Properties palette or Layer Properties Manager.

In conclusion, changing linetypes in AutoCAD is essential for adding visual variation to your drawings. Whether you want to modify individual object properties or apply linetypes to whole layers, AutoCAD offers flexible options to suit your needs. By following the methods mentioned in this tutorial, you can easily change linetypes and enhance the visual representation of your designs.
