How to Remove Hidden Lines in AutoCAD?

Steps to Remove Hidden Lines in AutoCAD

When working within AutoCAD, understanding how to manage the visibility of hidden lines can significantly enhance the clarity of your drawings. Removing or adjusting these lines is crucial for effective representation, especially when producing detailed architectural or engineering plans. Follow these steps to efficiently eliminate hidden lines in AutoCAD.

1. Open Your Drawing Layout

Begin by opening your existing drawing in AutoCAD. Ensure you are on the correct layout where you want to modify hidden lines. Confirm that your viewport is active if you’re working in a paper space layout.

2. Access the Viewport Properties

To modify hidden lines, you need to interact with the properties of the viewport:

1. Select the layout viewport by clicking its border.
2. Double-click the border to access the Properties palette. If the palette does not appear, you can type PROPERTIES in the command line to bring it up.

3. Modify Shade Plot Settings

Within the Properties palette, there is a specific setting that governs how hidden lines are displayed:

1. Locate the Shade Plot option in the Properties palette.
2. Click on the dropdown menu next to Shade Plot.
3. Select Hidden from the provided options. This change allows you to display hidden lines appropriately in your drawing.

4. Adjust Line Settings

If hidden lines remain visible after changing the shade plot:

1. Type HLSETTINGS at the command line and press Enter.
2. The Hidden Line Settings dialog will open, allowing you to configure various properties.
3. Modify the visibility settings as necessary and click OK.

5. Update Display in Paper Space

To secure the correct display in paper space layouts:

1. Type MVIEW at the command line and hit Enter.
2. Choose the option for S, which stands for shadeplot.
3. Then, type H to designate hidden lines for visibility.
4. Finally, select the viewport that you wish to update and apply the changes.

6. Confirm Line Type Scale Settings

If hidden lines still do not appear as intended, it’s crucial to check your line type scale settings:

1. Select the line that is not displaying correctly.
2. Open the Properties palette and verify the Linetype Scale.
3. Adjust the scale settings to ensure that dashed lines appear correctly. If the scale is too low, it may not render as expected.

Frequently Asked Questions

1. What are hidden lines used for in AutoCAD?
Hidden lines are utilized to represent edges and surfaces that are not directly visible in a particular view. They help convey the complete geometry of an object, ensuring clarity in technical drawings.

2. How do I fix dashed lines if they are not displaying correctly?
If dashed lines are not visible, check both the LTSCALE and PSLTSCALE variables. Ensure they are set correctly for your drawing’s units. You may need to reload your linetypes or purge any unused linetypes to solve this issue.

3. Why can’t I see my properties palette?
If your Properties palette is not visible, you can easily activate it by typing PROPERTIES into the command line and hitting Enter. You can also enable it through the View menu by selecting Toolbars > Properties.
