How to Do a Dashed Line in AutoCAD?

Understanding Dashed Lines in AutoCAD

To create a dashed line in AutoCAD, you need to adjust the line type settings in your project. Below is a detailed step-by-step guide on how to achieve this.

Step 1: Access the Layer Properties

1. Navigate to the Home tab on the ribbon.
2. Locate the Layers panel, then click on Layer Properties.

Step 2: Select the Line Type

1. In the Layer Properties Manager, find the Linetype column.
2. Click on the current linetype for the layer you wish to modify.

Step 3: Choose a Dashed Line Type

1. A dialog box labeled Select Linetype will open.
2. From the list, select the dashed line type you want to utilize. If a dashed line type is not available, you may need to load it from your AutoCAD linetype library.

Step 4: Assign the Dash Line to Your Objects

1. Once you have chosen your desired dashed linetype, confirm the selection and close the dialog box.
2. Now, go back to the drawing area and select the line or object you want to change to a dashed line.
3. Right-click and select Properties from the context menu.
4. In the Properties palette, find the Linetype option and select the new dashed line option from the dropdown list.
5. Press Esc to complete your selection.

Adjusting Line Type Scale

If your dashed line does not display correctly, it may be necessary to adjust the line type scale:

1. Select the dashed line you’ve created.
2. Open the Properties palette.
3. Identify the Linetype Scale setting, which is often set at 1.0 by default.
4. Increase this value to around 30 or a higher number until the dashed line appears as required.

Creating Custom Dotted Lines

If you need to create a custom dotted line:

1. Use the line segment tool to draw the desired shape.
2. Go to the Appearance section of the Properties tab on the right side.
3. Click on Stroke to explore stroke options.
4. Enable the option marked Dashed Line.
5. Enter specific values for the length of dashes and the gaps between them according to your preferences.

Making Hidden Lines Visible

If you need to ensure that hidden lines appear in your viewport:

1. Select the viewport where you would like to show hidden lines.
2. Navigate to the View tab.
3. Click the Palettes panel and select the Properties palette.
4. Under the Misc section, find the Shade Plot field, and change this to As Displayed.

Removing Dashed Lines or Adjusting Layout

To eliminate a dotted line or adjust the layout margins:

1. Access the Page Setup dialog by right-clicking on a layout tab in paper space.
2. Select your printer or plotter and click the Properties button to modify settings.
3. If necessary, adjust the margins in the configuration to fit your needs.
