How To View Hidden Lines In AutoCAD?

Understanding Hidden Lines in AutoCAD

Hidden lines are essential in technical drawings because they represent features not visible in the current view. Knowing how to display these lines can significantly enhance the clarity of a design.

Accessing Hidden Line View Options

  1. Open Your Project: Load the AutoCAD file you wish to work with.
  2. Navigate to the View Tab: Click on the ‘View’ tab located at the top of the workspace.
  3. Locate the Graphics Panel: Here, identify the ‘Graphics’ panel.
  4. Select Show Hidden: Click on the drop-down menu for ‘Show Hidden Lines’ to reveal hidden elements within your drawing.

Selecting Elements Effectively

  • Identify Overlapping Components: Hover your cursor over an element that might conceal others, such as a filled region over a wall.
  • Select the Element: Click on the overlapping element to activate the hidden lines feature for the elements being obscured.

Adjusting Line Type Scale

If hidden lines are not visible, it may be due to the line type scale being set too low. Here’s how to adjust:

  1. Select the Line: Click on the specific dashed line you wish to edit.
  2. Open Properties: Right-click and choose ‘Properties’ from the context menu.
  3. Modify the Scale: Look for the ‘Line Type Scale’ setting. Increase the value to make the dash pattern visible.

Editing Hidden Line Settings

  1. Command Prompt Access: Type HLSETTINGS in the command prompt and press Enter.
  2. Adjust Preferences: In the Hidden Line Settings dialog, modify the available options according to your preferences and click ‘OK’ to apply changes.

Utilizing Wireframe View

For better visualization of hidden lines, switch to Wireframe View:

  1. View Control Bar: Click on the View Control Bar at the top of the window.
  2. Select Visual Style: Change the style to ‘Wireframe’. This mode allows you to interact with hidden elements easily.
  3. Show Hidden Lines by Element: Return to the Graphics panel and select the option to show hidden lines.

Hiding Lines in a Viewport

To hide lines selectively:

  1. Select Viewport: Click on the viewport where you want to hide elements.
  2. Open Properties Inspector: Navigate to the Window menu and select ‘Properties Inspector’.
  3. Adjust Shade Plot Setting: In the ‘Misc’ section, find the Shade Plot list and choose ‘Hidden’.

Viewing Hidden Elements in Revit

For those working with Revit:

  1. View Tab: Click on the ‘View’ tab from the top menu.
  2. Reveal Hidden Elements: Click on the ‘Reveal Hidden Elements’ icon.
  3. Select Obscured Elements: In this mode, find and select elements that are hidden, and modify their visibility accordingly.

FAQ

1. What should I do if my hidden lines still do not appear even after adjusting properties?
Ensure that you’ve selected the correct viewport and that your line type scale settings are appropriate. If problems persist, check for visibility settings or layer states that may affect the display.

2. How can I permanently change the visibility settings for hidden lines in future projects?
You can modify your template files to include these settings by adjusting the line type scale and save them. This way, every new project will use these settings from the start.

3. Is there a way to easily toggle hidden lines on and off in AutoCAD?
Yes, use the ‘Show Hidden Lines’ option in the Graphics panel to quickly toggle the visibility of hidden lines without making permanent changes.
