Plot style configuration in AutoCAD - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a plot style in AutoCAD?

A plot style controls how objects are printed or plotted, including color, line weight, and screening.

beginner

Name two types of plot style tables in AutoCAD.

Color-dependent plot styles (CTB) and named plot styles (STB).

intermediate

How does a color-dependent plot style (CTB) work?

It assigns plot settings based on the color of objects in the drawing.

intermediate

What is the main advantage of using named plot styles (STB)?

They allow you to assign plot settings to objects regardless of their color, giving more flexibility.

beginner

How can you edit a plot style table in AutoCAD?

Use the Plot Style Manager to open and modify CTB or STB files, changing settings like lineweight and screening.

Which plot style type assigns settings based on object color?

A Object-based plot style

B Color-dependent plot style (CTB)

C Layer-based plot style

D Named plot style (STB)

Color-dependent plot styles (CTB) assign plot settings based on the color of objects.

What does STB stand for in AutoCAD plot styles?

A Named Plot Style Table

B Style Table

C Standard Table

D Screening Table

STB means Named Plot Style Table, which assigns styles by name, not color.

Which tool do you use to manage plot style tables in AutoCAD?

A Block Editor

B Layer Manager

C Plot Style Manager

D Properties Palette

Plot Style Manager is used to open and edit plot style tables.

What plot style setting controls the thickness of lines when printed?

A Lineweight

B Screening

C Color

D Transparency

Lineweight controls how thick lines appear on the printed output.

Which plot style type offers more flexibility by not depending on object color?

A Color-dependent plot style (CTB)

B Object-based plot style

C Layer-based plot style

D Named plot style (STB)

Named plot styles (STB) assign styles by name, allowing flexibility beyond color.

Explain the difference between color-dependent and named plot styles in AutoCAD.

Think about how styles are linked to objects in each type.

Describe how to edit a plot style table to change line thickness for printing.

Focus on the steps inside AutoCAD to access and change plot styles.

Practice

1. What is the main purpose of a plot style configuration in AutoCAD?

easy

A. To save drawings in different file formats

B. To create 3D models from 2D drawings

C. To control how drawings appear when printed, such as colors and lineweights

D. To automate drawing creation using scripts

Solution

1. Step 1: Understand plot style configuration role

   Plot style configuration sets visual properties like color and lineweight for printing.

2. Step 2: Compare options with purpose

   Only To control how drawings appear when printed, such as colors and lineweights describes controlling print appearance; others relate to different tasks.

3. Final Answer:

   To control how drawings appear when printed, such as colors and lineweights -> Option C

4. Quick Check:

   Plot style controls print appearance = A [OK]

Hint: Plot styles control print look, not drawing creation [OK]

Common Mistakes:

• Confusing plot styles with drawing creation tools
• Thinking plot styles save file formats
• Assuming plot styles automate drawing

2. Which of the following is the correct file extension for a color-dependent plot style table in AutoCAD?

easy

A. .stb

B. .dwg

C. .plt

D. .ctb

Solution

1. Step 1: Recall plot style file types

   Color-dependent plot styles use CTB files; named styles use STB files.

2. Step 2: Match file extensions

   .ctb is for color-based styles, .stb is for named styles, .plt and .dwg are unrelated.

3. Final Answer:

   .ctb -> Option D

4. Quick Check:

   Color-based plot style = .ctb [OK]

Hint: CTB = Color-based, STB = Named styles [OK]

Common Mistakes:

• Mixing up .ctb and .stb extensions
• Choosing .dwg which is a drawing file
• Selecting .plt which is a plotter file

3. Given a plot style table where color 1 is set to print as red with lineweight 0.5 mm, what will happen if an object in the drawing is color 1 and you print using this plot style?

medium

A. The object prints in red with lineweight 0.5 mm

B. The object prints in black with lineweight 1.0 mm

C. The object prints in its original color with default lineweight

D. The object does not print

Solution

1. Step 1: Understand color mapping in plot styles

   Color 1 is mapped to print as red with 0.5 mm lineweight in the plot style table.

2. Step 2: Apply plot style to object color

   Objects with color 1 print using the mapped color and lineweight, overriding original color.

3. Final Answer:

   The object prints in red with lineweight 0.5 mm -> Option A

4. Quick Check:

   Color 1 mapped to red, 0.5 mm lineweight = C [OK]

Hint: Plot style overrides object color and lineweight on print [OK]

Common Mistakes:

• Assuming object prints in original color ignoring plot style
• Confusing lineweight values
• Thinking object won't print if color is remapped

4. You created a new STB plot style but when printing, the styles do not apply. What is the most likely cause?

medium

A. The drawing is set to use CTB plot styles instead of STB

B. The plotter device is offline

C. The drawing file is corrupted

D. The printer driver is outdated

Solution

1. Step 1: Check plot style type used by drawing

   Drawings use either CTB (color-based) or STB (named) plot styles, not both simultaneously.

2. Step 2: Identify mismatch issue

   If drawing is set to CTB but you created STB styles, they won't apply during printing.

3. Final Answer:

   The drawing is set to use CTB plot styles instead of STB -> Option A

4. Quick Check:

   Plot style type mismatch = D [OK]

Hint: Match plot style type with drawing setting [OK]

Common Mistakes:

• Blaming printer or driver instead of plot style mismatch
• Ignoring plot style type setting in drawing
• Assuming file corruption causes style issues

5. You want to create a plot style that prints all objects with color 3 as dashed lines with a lineweight of 0.25 mm, but solid lines for all other colors. Which steps should you follow to configure this correctly?

hard

A. Change the drawing colors to 3 and set lineweight manually on each object

B. Edit the CTB file to set color 3 line style to dashed and lineweight 0.25 mm; leave others as solid

C. Use STB styles to assign dashed line style to color 3 and solid to others

D. Set the printer properties to print color 3 as dashed lines

Solution

1. Step 1: Choose correct plot style type

   Since the requirement is color-based, use a CTB file to map color 3 properties.

2. Step 2: Edit CTB file for color 3

   Set color 3 to print with dashed line style and 0.25 mm lineweight; keep other colors as solid lines.

3. Step 3: Apply plot style and print

   Assign this CTB to the drawing and print to see the effect.

4. Final Answer:

   Edit the CTB file to set color 3 line style to dashed and lineweight 0.25 mm; leave others as solid -> Option B

5. Quick Check:

   Color-based style edit in CTB = A [OK]

Hint: Use CTB for color-based line style changes [OK]

Common Mistakes:

• Trying to change line style via printer settings
• Changing object colors instead of plot style
• Using STB when color-based style is needed
