Wipeout for masking in AutoCAD - Step-by-Step Guide

Introduction

Wipeout lets you hide parts of your drawing by covering them with a white mask. This helps you focus on important details without deleting anything. It is useful when you want to clean up clutter or highlight specific areas.

When you want to hide overlapping lines or objects without deleting them

When you need to mask part of a drawing to add text or annotations clearly

When you want to create a clean background behind a logo or symbol

When you want to emphasize a section of a complex drawing by hiding distractions

When you want to prepare a drawing for printing with clearer visuals

Steps

Step 1: Click

- Home tab > Draw panel > Wipeout

The command line prompts you to specify the wipeout boundary

💡 You can also type 'WIPEOUT' in the command line and press Enter

Step 2: Specify

- Drawing area

You start defining the polygon boundary by clicking points around the area to mask

💡 Click points carefully to cover the exact area you want to hide

Step 3: Close

- Drawing area

The wipeout area is created and the selected part of the drawing is masked with a white fill

💡 Make sure to close the polygon by clicking the first point again or typing C and pressing Enter

Step 4: Adjust

- Properties palette

You can change the wipeout frame visibility or move the wipeout object as needed

💡 Toggle the wipeout frame on or off for easier editing

Before vs After

Before

Drawing shows overlapping lines and text cluttered together, making it hard to read

After

Wipeout masks the overlapping lines behind the text, making the text clear and easy to read

Settings Reference

Frame Visibility

📍 Properties palette > Wipeout Frame

Controls whether the boundary frame of the wipeout is visible or hidden

Default: On

Draw Order

📍 Right-click > Draw Order

Controls whether the wipeout covers other objects or is covered by them

Default: Depends on object order

Common Mistakes

Not closing the wipeout polygon

The wipeout area will not be created properly and no masking occurs

Always close the polygon by clicking the first point again or typing C and pressing Enter

Wipeout frame left visible and cluttering the drawing

The frame distracts from the clean masked area

Turn off the wipeout frame visibility in the Properties palette after creating the wipeout

Summary

Wipeout masks parts of a drawing with a white fill to hide unwanted details.

Use it to clean up clutter or highlight important areas without deleting objects.

Remember to close the polygon and manage the wipeout frame visibility for best results.

Practice

1. What is the main purpose of using Wipeout in AutoCAD drawings?

easy

A. To create 3D models from 2D drawings

B. To permanently erase objects from the drawing

C. To change the color of objects

D. To mask parts of a drawing without deleting them

Solution

1. Step 1: Understand Wipeout functionality and compare options

   Wipeout masks or hides parts of a drawing but does not delete the objects underneath. Only To mask parts of a drawing without deleting them correctly describes masking without deletion; others describe different functions.

2. Final Answer:

   To mask parts of a drawing without deleting them -> Option D

3. Quick Check:

   Wipeout = Masking without deletion [OK]

Hint: Remember: Wipeout hides, does not erase [OK]

Common Mistakes:

• Confusing wipeout with erase command
• Thinking wipeout changes object color
• Assuming wipeout creates 3D models

2. Which of the following is the correct way to create a wipeout in AutoCAD?

easy

A. Use the WIPEOUT command and select an existing polyline or draw a new boundary

B. Use the ERASE command on the objects to hide

C. Use the HATCH command with a solid fill

D. Use the LINE command to draw over objects

Solution

1. Step 1: Recall wipeout creation method and evaluate other options

   The WIPEOUT command allows creating a masking area by selecting or drawing a boundary. ERASE deletes objects, HATCH fills areas but doesn't mask, and LINE just draws lines.

2. Final Answer:

   Use the WIPEOUT command and select an existing polyline or draw a new boundary -> Option A

3. Quick Check:

   WIPEOUT command = Create mask [OK]

Hint: Use WIPEOUT command, not ERASE or HATCH [OK]

Common Mistakes:

• Trying to erase objects instead of masking
• Using hatch instead of wipeout for masking
• Drawing lines over objects thinking it hides them

3. Given a drawing with overlapping objects, what will be the visible result after applying a wipeout with a closed polyline boundary over the top objects?

medium

A. The objects under the wipeout boundary will be hidden but still exist

B. All objects inside the boundary will be deleted permanently

C. The wipeout boundary will change the color of objects inside it

D. The wipeout will convert objects inside the boundary to a block

Solution

1. Step 1: Understand wipeout effect on objects and analyze options

   Wipeout hides objects under its boundary but does not delete or alter them. Only The objects under the wipeout boundary will be hidden but still exist correctly states objects are hidden but remain; others describe deletion or changes which do not happen.

2. Final Answer:

   The objects under the wipeout boundary will be hidden but still exist -> Option A

3. Quick Check:

   Wipeout hides objects, does not delete [OK]

Hint: Wipeout hides, does not delete objects [OK]

Common Mistakes:

• Assuming wipeout deletes objects
• Thinking wipeout changes object properties
• Believing wipeout converts objects to blocks

4. You created a wipeout but it is not hiding the objects underneath. What is the most likely cause?

medium

A. The wipeout boundary is not a closed polyline

B. The objects are locked and cannot be hidden

C. The wipeout frame is turned off or frozen

D. The wipeout command was not run with administrative rights

Solution

1. Step 1: Check wipeout frame visibility and evaluate other causes

   If the wipeout frame is off or frozen, the mask effect may not display properly. Objects being locked does not prevent hiding; boundary shape matters but wipeout can create boundaries; admin rights are unrelated.

2. Final Answer:

   The wipeout frame is turned off or frozen -> Option C

3. Quick Check:

   Frame visibility affects wipeout masking [OK]

Hint: Check wipeout frame visibility if masking fails [OK]

Common Mistakes:

• Assuming locked objects prevent masking
• Ignoring wipeout frame visibility
• Thinking admin rights affect wipeout

5. You want to mask a complex area in your drawing that has multiple overlapping objects and irregular shapes. Which approach using wipeout will give you the cleanest result?

hard

A. Draw solid hatch patterns over the objects to mask them

B. Create a single closed polyline that outlines the entire area and use it as the wipeout boundary

C. Use the erase command on all objects inside the area

D. Create multiple small wipeouts for each object separately

Solution

1. Step 1: Consider masking efficiency and compare alternatives

   A single closed polyline wipeout covers the entire area cleanly without gaps or overlaps. Multiple small wipeouts can cause overlaps and complexity; erase deletes objects; hatch does not mask underlying objects.

2. Final Answer:

   Create a single closed polyline that outlines the entire area and use it as the wipeout boundary -> Option B

3. Quick Check:

   Single closed polyline = clean mask [OK]

Hint: Use one closed polyline for complex area masking [OK]

Common Mistakes:

• Using many small wipeouts causing clutter
• Erasing objects instead of masking
• Using hatch which doesn't hide objects
