How To Display Linetype In AutoCAD?

Understanding Linetypes in AutoCAD

Linetypes are essential visual attributes assigned to geometric objects in AutoCAD. They dictate how lines—whether dashed, dotted, or continuous—appear within your drawings. If linetypes are not displaying correctly, it could be due to a variety of factors including scale settings or text height configurations.

Checking Linetype Visibility

To ensure linetypes are visible in your AutoCAD drawing, follow these steps:

  1. Access the Home Tab: Open AutoCAD and navigate to the Home tab on the ribbon.
  2. Select the Linetype Drop-Down: Locate the Properties panel and click on the Linetype drop-down menu.
  3. Set the Current Linetype: From the list, choose the desired linetype to set it as current. Confirm that this linetype is appropriate for your drawing requirements.

Adjusting Linetype Scale Settings

Linetype visibility is influenced by several critical scale variables. Here’s how to adjust them:

  1. Command Line Input: Type and enter the command LTSCALE in the command line. Set this value to 1 to standardize line type visibility across your layout.
  2. Adjust CELTSCALE: Enter the command CELTSCALE and also set it to 1. This affects the linetype scales for your objects.
  3. Modify PSLTSCALE: Lastly, type PSLTSCALE and assign it a value of 1 as well. This will ensure consistent linetype appearance in both model and paper space.
  4. Set MSLTSCALE: Similarly, enter MSLTSCALE and ensure the value is set to 1 to maintain coherence across viewports.

Managing Text Height in Linetypes

If text within a linetype is not displaying correctly, adjusting the text style’s height may be necessary:

  1. Open Style Settings: Execute the STYLE command from the command line.
  2. Select Text Style: Choose the text style linked with your linetype.
  3. Set Height to Zero: Change the text height to 0. This adjustment prevents the text from being constrained by a specific height, allowing it to render appropriately in the drawing.

Loading Custom Linetypes

If custom linetypes are required, follow these procedures to load them into your drawing:

  1. Open Linetype Manager: Go to the Linetype drop-down and select ‘Other’ to access the Linetype Manager.
  2. Loading Linetypes: In the Linetype Manager dialog box, click Load.
  3. Select LIN File: In the ‘Load or Reload Linetypes’ dialog, click on File to browse your system for a LIN file.
  4. Choose and Open File: Locate your desired LIN file, select it, and click Open to load it into your project.

Changing Default Linetypes

To adjust the default linetype for all new objects in your drawing:

  1. Navigate to Layer Properties: Click on the Home tab and find the Layers panel. Select the Layer Properties tool.
  2. Select Layer: In the Layer Properties Manager, identify the layer whose linetype you wish to alter.
  3. Change Linetype: Under the Linetype column, click the current linetype and select a new one from the dialog box that appears.

Creating Custom Linetypes

Custom linetypes can enhance your drawings creatively. Here’s how to create one:

  1. Access Make Linetype Tool: Navigate to the Express menu and select Tools, then pick ‘Make Linetype’.
  2. Name Your Linetype: In the prompted dialog, enter a name for your linetype and save it.
  3. If Desired, Add Description: Optionally, provide a description for this linetype before moving on.
  4. Specify Points: Finally, define the starting and ending points of your new linetype.

FAQs

1. Why do my linetypes look different in model space compared to paper space?
This discrepancy often arises from incorrect linetype scale settings (LTSCALE, PSLTSCALE). Ensure these variables are set uniformly to maintain consistency.

2. How do I reset my linetype settings to default?
You can reset linetype settings by setting all relevant variables (LTSCALE, CELTSCALE, PSLTSCALE, MSLTSCALE) back to their defaults, usually a value of 1.

3. What should I do if linetypes still do not show properly even after adjustments?
If issues persist, check whether any viewport settings are conflicting or review the layer settings for visibility properties related to the linetypes used.
