How Do You Make a Polyline Thicker in AutoCAD?

by

In AutoCAD, a polyline is a series of connected line segments or arc segments that form a continuous shape. By default, the thickness of a polyline is set to 0, which means it appears as a thin line when plotted or displayed. However, there may be instances where you want to make the polyline thicker to enhance its visibility or highlight its importance within your drawing.

Changing the Lineweight of a Polyline

To make a polyline thicker in AutoCAD, you can adjust its lineweight property. Lineweight refers to the thickness of the lines used to display objects in AutoCAD.

Here are the steps to change the lineweight of a polyline:

  1. Select the polyline that you want to make thicker.
  2. Right-click on the selected polyline and choose “Properties” from the context menu.
  3. In the Properties palette that appears, locate the “Lineweight” property.
  4. Click on the value next to “Lineweight” and choose a higher value from the dropdown list. The higher the value, the thicker the line will appear.

Note: The actual appearance of lineweights may vary depending on your plotter or printer settings. It’s recommended to test different lineweights before finalizing your drawing for printing or sharing.

Using Linetypes for Thick Polylines

If you want more control over how your thick polylines appear, you can also use custom linetypes. A linetype is a pattern of dashes, dots, and gaps applied along a line or polyline segment.

To create a custom linetype for thick polylines:

  1. Type “LINETYPE” in the command line and press Enter.
  2. In the Linetype Manager dialog box, click on “Load” to load a linetype definition file (.lin).
  3. Browse and select a linetype definition file that includes thick lines.
  4. Click “OK” to load the linetype.

Once you have loaded a linetype with thick lines, you can apply it to your polyline by following these steps:

  1. Select the polyline that you want to make thicker.
  2. Type “PEDIT” in the command line and press Enter.
  3. In the Edit Polyline dialog box, select “Width” from the options list.
  4. Enter a value for the width of the polyline. This value will determine how thick the polyline appears using the loaded linetype.
  5. Click “OK” to apply the width and exit the Edit Polyline dialog box.

Note: Custom linetypes can be created using specialized software or by editing .lin files manually. Consult AutoCAD documentation or online resources for more information on creating custom linetypes.

Conclusion

Making a polyline thicker in AutoCAD can be achieved by adjusting its lineweight or applying custom linetypes. By increasing the visibility of your polylines, you can effectively communicate your design intent and improve overall drawing clarity.

Experiment with different lineweights and linetypes to find what works best for your specific needs. Remember to consider plotter or printer settings when finalizing your drawing for printing or sharing.

Now that you know how to make a polyline thicker in AutoCAD, you can enhance your drawings and create more visually engaging designs.
