Understanding the Wipeout Command in AutoCAD
The Wipeout command in AutoCAD serves to create a mask over specified areas, allowing for the concealment of underlying objects. By employing the current background color as the masking property, users can effectively hide distractions in their drawings. The area masked by the Wipeout command can be defined by using a wipeout frame, which can be toggled on or off during the editing process.
Creating a Wipeout Object
To initiate a wipeout object in AutoCAD, follow these steps:
- Open the drawing where you wish to add the wipeout.
 - Type WIPEOUT in the command line and press Enter.
 - Choose the option to define the perimeter points by clicking on the drawing area.
 - Continue clicking until you have outlined the area to be wiped out and then press Enter to finalize the selection.
 
Incorporating a Wipeout into a Block
If you want to add a wipeout to an existing block:
- Select the block reference in your drawing.
 - Right-click and choose Edit Block to open the Block Editor.
 - Utilize the WIPEOUT command to create a wipeout shape covering the necessary area within the block.
 - Select the new wipeout, right-click, and navigate to Basic Modify Tools > Display Order > Send to Back to ensure it masks the intended items.
 - Save your changes and exit the Block Editor.
 
Wipeout for Text Objects
To add a wipeout behind text:
- Activate the command line and enter WIPEOUT, then press Enter.
 - Choose the Offset option to adjust the wipeout relative to the text.
 - To manage the appearance of the wipeout frame, toggle the WIPEOUTFRAME system variable by setting it to 1 (show) or 0 (hide).
 
Creating a Wipeout from Polylines
To use a polyline for a wipeout:
- Start with a closed polyline that outlines the desired area.
 - Invoke the WIPEOUT command from the command line.
 - When prompted, select the Polyline option and choose your existing polyline.
 - Press Enter to complete the mask creation.
 
Adjusting Wipeout Display Settings
If you need to control the visibility of wipeout frames:
- Access the command line and input the WIPEOUT command.
 - Select the frames option to toggle the appearance by entering the settings for on or off.
 - View the effects on your drawing accordingly.
 
Masking Additional Objects
When masking a block or object:
- Select the block you want to use as a mask.
 - Go to the Mask Block Reference tab and find the Modify panel.
 - Choose Attach Objects and select the object to be masked.
 - Select a display representation from the options available, then finalize by clicking OK.
