How to Highlight Areas in AutoCAD?

Steps to Highlight Areas in AutoCAD

When working in AutoCAD, highlighting areas can significantly enhance your drawing process, making it easier to identify and manipulate specific components. To highlight areas effectively, follow these detailed steps.

Adjusting Selection Options

1. Access the Options Menu: Start by right-clicking anywhere in the drawing area. This action will bring up a context menu.

2. Navigate to the Selection Tab: From the context menu, select the ‘Options’ entry. Once the Options dialog appears, locate and click on the ‘Selection’ tab.

3. Customize Your Preferences: Within the Selection tab, you’ll find several settings that can be adjusted:
   • Previewing Selected Objects: You can enable or disable the preview of objects when selected. This feature is useful for visual confirmation.
   • Highlighting Selected Objects: Ensure that the option to highlight selected objects is enabled. This option makes it easier to see which elements are currently active.

Marking Areas with Hatching

1. Open the Hatch Tool: Go to the Content Editor tab. Find the Tools panel, then locate the Hatch drop-down menu and select ‘Create’.

2. Select Areas to Hatch: Click in the drawing area to choose a point within each distinct area you want to mark. After selecting the first point, press ‘Enter’ to confirm your selection.

3. Position the Hatch Icon: Carefully place the hatch icon in a noticeable position within the marked area. This helps in associating the hatch visually with the specific section you are highlighting.

Highlighting Text Elements

1. Access the Text Editing Settings: To highlight textual elements, right-click on the specific text you want to modify.

2. Modify Highlight Color: Select the ‘Editor settings’ option from the menu. Here, find the ‘Text Highlight Color’ feature and enable it to change the color according to your preferences.

Using Marking Symbols

1. Select the Annotate Tab: Click on the Annotate tab, then find the Symbols panel.

2. Choose Marking Options: From the Symbols panel, open the drop-down menu and select ‘GOST Marking & Stamping’.

3. Attach Marking Symbols: Click on the object you wish to mark. If attaching to a line, determine the start point for the leader in the drawing area. Press ‘Enter’ to finalize the placement of the marking symbol.

Managing Highlight Settings

1. Change Highlight Preferences: To disable automatic highlighting, type "selectionpreview" in the AutoCAD command line and hit Enter.

2. Update Setting Value: When prompted, change the setting value from 1 (enabled) to 0 (disabled). This adjustment will stop AutoCAD from highlighting items until they are selected manually.

Changing Highlight Colors

1. Access the Command Line: Starting from AutoCAD 2025, you have the option to customize highlight colors.

2. Use the SELECTIONEFFECTCOLOR Variable: Enter the command "SELECTIONEFFECTCOLOR" in the command line. Adjust the color value according to your preference to change how highlighted selections appear.

Using Selection Cycling

1. Enable Selection Cycling: Input "SELECTIONCYCLING" into the command prompt and press Enter.

2. Toggle the Setting: Enter ‘2’ to enable the selection cycling display, allowing you to see overlapping object selections more clearly, or ‘0’ to turn this feature off.
