How to Show Dotted Line in AutoCAD?

Understanding Dotted Lines in AutoCAD

Dotted lines in AutoCAD often represent specific elements in your drawing, like margins or sections of your workspace. If you are having trouble displaying these lines, follow these steps to ensure they show correctly.

Step 1: Access the Line Properties

First, you need to select the object for which you want to apply or modify the dotted line. Here’s how to do it:

1. Select Your Object: Click on the line or object that you aim to change.
2. Open Properties Panel: Right-click on the selected object and choose “Properties.” Alternatively, you can type PROPERTIES in the command line and hit Enter.
3. Verify Linetype: In the Properties panel, look for the “Linetype” option. Make sure the line type is set to one of the dashed or dotted variant types available.

Step 2: Adjust the Linetype Scale

If your dotted line is not appearing as expected, the linetype scale may need adjustment:

1. Enter the Command: Type LTSCALE in the command line and press Enter.
2. Set a Value: Input a larger value if the dotted line is not showing clearly. This value determines how spaced out the dashes are. A common initial value is 1, but you might need to try higher numbers based on your layout.
3. Update Individual Object: After changing the global Linetype scale, you might also want to check the LTSCALE for specific objects if they don’t seem to be reflecting the changes. Use the command CELTSCALE while those objects are selected.

Step 3: Configure Your Page Setup

Improper page setup can prevent dotted lines from displaying correctly. Here’s how to configure it:

1. Open Page Setup: Right-click on your layout tab in the model space and select “Page Setup Manager.”
2. Modify Printer/Plotter: Choose the printer or plotter you are using and click on “Properties.”
3. Check Margins: Look for margin settings. Sometimes, margins can obscure lines. Adjust them to appropriate values, or set them to 0 if necessary.

Step 4: Enable Linetype Generation

Enabling linetype generation is essential for ensuring that dots and dashes are displayed correctly on polylines:

1. Open Properties Palette: Right-click in the drawing area and select “Properties.”
2. Set Linetype Generation: Locate “Linetype Generation” and select “Enabled.” This ensures that the linetype will not be affected by the shape or segments of polylines.

Step 5: Check PSLTSCALE

The PSLTSCALE system variable determines how linetypes are displayed relative to viewport scaling:

1. Check PSLTSCALE: Type PSLTSCALE in the command line and hit Enter.
2. Adjust Value: Set it to 1 if it’s not already. This setting ensures that your linetypes are properly scaled within the layout viewport.

FAQ

1. What are the different types of linetypes available in AutoCAD?
AutoCAD includes various linetypes like continuous, dashed, dotted, hidden, center, and phantom lines. Each type serves specific purposes within drafting.

2. How do I reset my AutoCAD settings to default for linetypes?
To reset settings, go to the ‘Options’ dialog box, select the ‘Profiles’ tab, and choose the ‘Reset’ option for your active profile. Be sure to back up your current settings first as this will restore defaults.

3. Why aren’t my changes showing on the plot?
If your linetype adjustments aren’t appearing in the printed output, ensure that the correct printer settings are configured and the desired linetypes are actually loaded into your drawing file. Checking your paper setup and ensuring the scale and visibility settings are correct will also help.
