How to Wipe Out a Block in AutoCAD

Understanding Wipeout Features in AutoCAD

Wipeout is a powerful tool in AutoCAD that allows users to mask parts of a drawing. By creating a polygonal area that simulates being filled with the background color, it effectively hides underlying objects. This can streamline presentations or focus attention on certain areas of the drawing by obscuring unnecessary elements.

Steps to Wipe Out a Block in AutoCAD

To successfully wipe out a block reference in AutoCAD, follow these detailed steps:

1. Select the Block Reference: Use your cursor to click on the block you wish to edit. It will usually highlight to indicate selection.
2. Access the Block Editor: Right-click on the selected block and choose the option to open it in the Block Editor. This interface allows for modifications specific to that block.
3. Utilize the Wipeout Command: Type in the command WIPEOUT in the command line and hit Enter. The command will prompt you to define the perimeter of the area that you want to wipe out. Click to specify the corners of the polygon that you want to create. Ensure that the points delineate the area completely.
4. Adjust the Wipeout Properties: Once you’ve created the wipeout, select it immediately. Right-click to access properties, where you may apply changes regarding the display order of objects.
5. Send to Back: To ensure the wipeout masks the desired elements properly, navigate to the “Display Order” option by right-clicking again. Choose “Send to Back” to position it behind the other elements effectively. This allows your wipeout to take precedence in the drawing.
6. Save and Exit: After making the desired modifications, make sure to save your work. Close the Block Editor to return to your main drawing area, where the changes will be reflected.

Additional Tips for Using Wipeouts

When working with wipeouts in AutoCAD, consider using the following guidelines for optimal results:

• Background Color: Ensure that the wipeout matches the background color of your drawing. You may adjust this within the Wipeout properties to ensure seamless integration.
• Polygon Shapes: Always remember that the polygonal shape for the wipeout must be closed, using only line segments. This form ensures that it effectively masks the intended area.
• Performance: Large or complex wipeouts can affect drawing performance. Keep this in mind if using multiple masks in a single drawing.

FAQ

1. What should I do if the Wipeout command isn’t working?

Check to ensure that you are operating within the Block Editor when trying to apply a wipeout. Additionally, ensure you have selected the correct object type and haven’t inadvertently created overlapping shapes.

2. Can I edit a wipeout after creating it?

Yes, you can select the wipeout and adjust its properties at any time. You can also recreate it, should the need arise, without permanently impacting the original design.

3. Will wipeouts affect my printing or plotting?

No, wipeouts are designed to mask areas visually in the drawing interface, but they do not impact actual printing or plotting of underlying objects. Make sure to check your print preview settings to verify the effects.
