How Do You Show Line Thickness in AutoCAD?

In AutoCAD, line thickness is an essential aspect of creating precise and visually appealing drawings. By adjusting the line thickness, you can emphasize certain elements or differentiate between different objects or layers. In this tutorial, we will explore various methods to show line thickness in AutoCAD.

1. Line Weight Settings

AutoCAD provides a comprehensive set of tools to control line weights. To access these settings, navigate to the “Lineweight” menu located in the “Properties” panel or use the command “LWEIGHT.” Here, you can assign specific line weights to different layers or individual objects.

To change the line weight of an object, select it and adjust the “Lineweight” property in the “Properties” panel. Alternatively, you can type “LWEIGHT” in the command bar and press Enter to open a dialog box where you can specify the desired line weight.

2. Lineweight Scale

In addition to assigning line weights directly, AutoCAD allows you to control their display scale using a feature called “Lineweight Scale.” This feature ensures that line weights appear consistent regardless of zoom level or output scale.

To set the lineweight scale, go to the “Options” menu by typing “OPTIONS” in the command bar and pressing Enter. In the dialog box that appears, navigate to the “Display” tab and locate the “Lineweight Display” section. Here, you can choose between two options:

  • Default (Use Object Lineweight): This option displays lines using their assigned lineweights without any scaling.
  • Scaled Lineweights: Selecting this option allows you to define a custom lineweight scale factor. By adjusting this value, you can control the display thickness of all lines in your drawing.

Experiment with different lineweight scale values to achieve the desired visual effect for your drawing.

3. Plotting Line Weights

When printing or plotting your AutoCAD drawings, it is important to ensure that line weights are accurately represented on paper or in digital formats. To achieve this, you need to configure the plot settings correctly.

To access the plot settings, type “PLOT” in the command bar and press Enter. In the plot dialog box, select the desired plotter or printer and click on “Properties” or “Custom Properties.”

In the printer/plotter properties window, locate the “Plot Style Table (Pen Assignments)” section. Here, you can choose between two options:

  • Color-Dependent Plot Styles: This option plots lines using their assigned colors without considering lineweights.
  • Named Plot Styles: Selecting this option allows you to use custom plot styles that consider both colors and lineweights. You can create or modify these plot styles in AutoCAD’s “Plot Style Manager.”

By selecting a named plot style that supports lineweight scaling, you can ensure accurate representation of line thicknesses during plotting.

Conclusion

In AutoCAD, showing line thickness is crucial for creating clear and professional drawings. By understanding and utilizing tools such as line weight settings, lineweight scaling, and proper plotting configurations, you can achieve precise and visually appealing results in your AutoCAD projects.
