Understanding Wipeout Functionality in AutoCAD
Wipeout is a powerful feature in AutoCAD that allows users to conceal parts of the drawing, creating a clean and focused display for specific elements. This capability is essential for presenting drafts clearly, especially when overlaying various design components.
What is Wipeout?
Wipeout creates a shape within your drawing that appears transparent but blocks out whatever is beneath it. It’s particularly useful when you want to emphasize certain portions of your drawing while hiding irregularities or complex backgrounds.
How to Create a Wipeout
-
Activate Wipeout Command:
- Start by typing
WI
in the command line or navigate to the Draw dropdown menu, then select Wipeout.
- Start by typing
-
Define the Boundary:
- Click to create points that define the perimeter of the area you want to mask. For precision, consider using a closed polyline as the boundary.
-
Finalize the Command:
- Once your boundary is specified, press Enter to execute the wipeout. If you used a polyline, a prompt may appear asking if you’d like to delete it. Choose “Yes” to remove it from the drawing.
Making Wipeout Lines Invisible
To ensure that the lines used to create a wipeout do not appear in the final output, follow these steps:
-
Select the Wipeout Object:
- Click on the wipeout area you’ve created to select it.
-
Adjust Properties:
- Right-click and select Properties from the context menu. This opens the Properties palette.
-
Change the Visibility Settings:
- In the Properties palette, look for the option that controls visibility or display settings. Set it to a “No” or “False” state, which will render the wipeout lines invisible or transparent in the drawing view.
-
Confirm Changes:
- Check that the changes have taken effect by zooming out and reviewing your drawing. The lines defining the wipeout should no longer be visible.
Removing All Wipeouts from a Drawing
If you wish to erase all wipeout objects from your drawing, you can do so by following these steps:
-
Select the Area:
- Use a selection window or click individually to select all the elements, including wipeouts, in the desired area.
-
Execute the Erase Command:
- Type
ERASE
and press Enter. When prompted if you wish to remove the selected objects, confirm your selection.
- Type
-
Use the Trim Command (if necessary):
- For any remaining elements outside your defined boundary, you can use the TRIM command with a fence selection to clean up the drawing further.
FAQs
Q1: What types of boundaries can I use with the Wipeout command?
You can use polylines or simply click to create the boundary manually. A closed polyline or polygon is preferred for a clear and defined mask.
Q2: Can I edit an existing wipeout?
Yes, you can select the wipeout object and adjust its boundaries by right-clicking to access properties or using the grips to reshape them.
Q3: How can I change the background color in AutoCAD to enhance the visibility of the wipeout?
Right-click on the drawing area, select Options, navigate to the Drafting tab, click on Colors, and change the 2D model space uniform background to your desired color, ensuring better contrast with the wipeout areas.
