How to Create Linetype in AutoCAD?

Understanding Linetype in AutoCAD

Linetype refers to the visual representation of lines in drawings, encompassing various styles such as solid, dotted, dashed, and more. These visual cues help distinguish between different elements in a design. Adjusting linetypes is essential for conveying information effectively within a project.

Steps to Create a New Linetype

Creating a custom linetype in AutoCAD involves several systematic steps:

1. Access the Express Tools:

   • On the ribbon, navigate to the Express Tools tab.
   • Locate the Tools panel.

2. Invoke the Linetype Creation Command:

   • Click on the Make Linetype option. This command will prompt the system to either create a new linetype or allow you to select an existing linetype file (*.lin).
3. Choose or Create a Linetype:
   • If creating a new linetype, follow the prompts to define the pattern using symbols or line styles.
   • If selecting an existing one, browse through your linetype files and select the desired option.

Frequency of Linetypes in AutoCAD

When starting a new project in AutoCAD, only the Continuous linetype is typically loaded by default. This design choice keeps file sizes manageable. To enhance your drawing, additional linetypes need to be loaded as required.

Common Issues with Linetype Display

If linetypes aren’t showing correctly in your drawings, you may need to check a couple of settings:

1. Verify Text Styles:
   • If a linetype includes text but doesn’t display correctly, it might be due to a defined height in the text style.
   • Use the STYLE command to adjust the text height to zero, allowing it to display properly on your drawing.
