How To Use Psltscale In AutoCAD?

Understanding PSLTSCALE in AutoCAD

When working in AutoCAD, proper representation of linetypes in different viewports is essential. The PSLTSCALE system variable plays a critical role in ensuring that the linetype scale remains consistent when viewing the drawing in various zoom levels within a layout viewport. Configuring this variable appropriately allows for preservation of linetype appearances regardless of how deep into the layout a user zooms.

Setting the PSLTSCALE Variable

  1. Open the Drawing: Launch AutoCAD and open the drawing file where you want to adjust the linetype scaling.

  2. Access the Command Line: Press the command line interface at the bottom of the AutoCAD window to enter commands directly.

  3. Type PSLTSCALE: Enter the command PSLTSCALE and press [Enter].

  4. Configure the Value:

    • A value of 1 will enable linetypes to scale uniformly across model space and layout viewports.
    • Setting it to 0 disables this feature, which may lead to inconsistent linetype appearances in different viewports.
  5. Confirm Changes: After setting the value, press [Enter] again to finalize your input.

  6. Regenerate the Drawing: To see the changes applied, type REGEN in the command line and hit [Enter]. This refreshes the drawing and updates any visual changes.

Best Practices for Linetype Scaling

To achieve the best visual results when working with linetypes in AutoCAD, consider the following practices:

  • Check LTSCALE: Ensure the LTSCALE variable is set correctly; typically, it should be half of the drawing scale factor. For instance, if your drawing scale factor is 48, set LTSCALE to 24.

  • Consider Viewport Settings: Each viewport can have individual settings affecting the appearance of linetypes. Confirm that viewport-specific settings are not overriding your global configurations.

  • Experiment with CELTSCALE: The CELTSCALE variable influences the current object’s linetype scale. Align it appropriately based on your design requirements to maintain consistency.

Creating and Managing Linetypes

  1. Open Linetype Manager: Type LINETYPE in the command line to open the Linetype Manager dialog.

  2. Load New Linetypes: Click on ‘Load’ to browse and select additional linetype definitions if required.

  3. Create Custom Linetypes: Go to the Express Tools menu, select “Make Linetype,” and follow the prompts to define your linetype parameters.

  4. Apply Linetype: After you have created or loaded a linetype, apply it to the objects in your drawing as needed.

Frequently Asked Questions (FAQs)

1. What happens if I set PSLTSCALE to 0?
Setting PSLTSCALE to 0 disables the uniform linetype scaling, causing inconsistencies in line appearances when zooming in or out within layout viewports.

2. How does LTSCALE affect my drawing?
LTSCALE directly influences how linetypes appear in model space. If this variable is not configured correctly, dashed and dotted lines may not display as intended.

3. Can I change linetypes after they are applied?
Yes, you can modify linetypes after applying them to objects. Access the Properties Palette or Linetype Manager to make adjustments as required.
