AutoCAD Dimensioning and Annotation 4 — Questions and Answers
Question 1: In a dimension style, what does the 'Fixed Length Extension Lines' option do?
- Sets all extension lines to a uniform length regardless of the distance from the dimension line to the object (Correct answer)
- Locks extension lines so they cannot be moved
- Sets the extension line gap to a fixed value
- Prevents extension lines from being suppressed
Correct answer: Sets all extension lines to a uniform length regardless of the distance from the dimension line to the object
Fixed Length Extension Lines forces all extension lines to a set length measured from the dimension line toward the dimensioned object, creating a uniform appearance.
Question 2: What does the CANNOSCALE system variable control?
- The current annotation scale for annotative objects in the active viewport (Correct answer)
- The scale of non-annotative text only
- The canonical scale factor for dimension arrowheads
- The canvas scale of the model space grid
Correct answer: The current annotation scale for annotative objects in the active viewport
CANNOSCALE stores the current annotation scale, which AutoCAD uses to determine which annotation representations are visible in the active viewport.
Question 3: Which command allows you to add the current viewport's annotation scale to an annotative object that does not yet support that scale?
- OBJECTSCALE (Correct answer)
- SCALELISTEDIT
- ADDSCALE
- ANNOAUTOSCALE
Correct answer: OBJECTSCALE
OBJECTSCALE lets you add or delete annotation scales from selected annotative objects so they display correctly in additional viewports.
Question 4: In a geometric tolerance frame, what does the material condition modifier 'M' inside a circle represent?
- Maximum Material Condition (MMC) — the condition where the feature contains the most material (Correct answer)
- Minimum Material Condition
- Measured dimension modifier
- Modifiable tolerance
Correct answer: Maximum Material Condition (MMC) — the condition where the feature contains the most material
The circled M symbol in a feature control frame indicates Maximum Material Condition (MMC), meaning the part is at its heaviest—smallest hole or largest shaft.
Question 5: What is the role of the DIMCONTINUE command relative to the last placed dimension?
- Creates a chain of dimensions end-to-end from the second extension line of the previous dimension (Correct answer)
- Creates dimensions all measured from the same first extension line baseline
- Continues a broken dimension line
- Copies the last dimension style to the next dimension
Correct answer: Creates a chain of dimensions end-to-end from the second extension line of the previous dimension
DIMCONTINUE (also accessible via the Continue button) places successive dimensions in a chain, where each new dimension starts from the second extension line of the previous one.
Question 6: When DIMASSOC is set to 2, what behavior does AutoCAD exhibit when dimensioned geometry is moved?
- Dimensions update automatically because they are fully associative to the definition points on the geometry (Correct answer)
- Dimensions must be manually updated with DIMREGEN
- Dimensions remain in their original position with no update
- Dimensions become non-associative after one move
Correct answer: Dimensions update automatically because they are fully associative to the definition points on the geometry
DIMASSOC=2 creates fully associative dimensions whose definition points are attached to the geometry, so dimensions update automatically when the geometry moves or changes.
Question 7: Which option in the MTEXT editor inserts an automatic list with letters, numbers, or bullets?
- Bullets and Lists on the Paragraph panel of the Text Editor ribbon tab (Correct answer)
- The LIST command within MTEXT
- \L formatting code
- Right-click > Numbering
Correct answer: Bullets and Lists on the Paragraph panel of the Text Editor ribbon tab
The Bullets and Lists dropdown on the MTEXT ribbon's Paragraph panel lets you apply lettered, numbered, or bulleted automatic lists to MTEXT content.
