AutoCAD Dimensioning and Annotation 2 — Questions and Answers
Question 1: Which dimension style override allows you to change the dimension unit format for a single dimension without modifying the parent style?
- DIMOVERRIDE command (Correct answer)
- DIMEDIT command
- DIMSTYLE command with Apply option
- PROPERTIES palette Unit Format field
Correct answer: DIMOVERRIDE command
DIMOVERRIDE lets you change specific dimension variables for selected dimensions without altering the named style.
Question 2: What does the DIMJUST system variable control?
- Horizontal justification of dimension text (Correct answer)
- Vertical position of dimension text
- Justification of multiline text in dimensions
- Arrow justification at extension line origins
Correct answer: Horizontal justification of dimension text
DIMJUST controls the horizontal placement of dimension text relative to the dimension line (centered, left, right, or over extension lines).
Question 3: When using the LEADER command versus the MULTILEADER command, what is a key functional difference?
- MULTILEADER supports multiple leader lines attached to one annotation block (Correct answer)
- LEADER can attach to multiple objects simultaneously
- MULTILEADER is only for geometric tolerances
- LEADER automatically creates an MText object
Correct answer: MULTILEADER supports multiple leader lines attached to one annotation block
MULTILEADER (MLEADER) allows multiple leader lines to converge on a single content block, while legacy LEADER creates a single leader with spline or straight segments.
Question 4: In a dimension style, what does setting 'Fit Options' to 'Text Only' do when space is tight between extension lines?
- Moves only the text outside the extension lines while keeping arrows inside (Correct answer)
- Moves only the arrows outside while keeping text inside
- Moves both text and arrows outside
- Scales the text to fit inside
Correct answer: Moves only the text outside the extension lines while keeping arrows inside
The 'Text Only' fit option moves the dimension text outside when space is insufficient but attempts to keep the arrowheads between the extension lines.
Question 5: What is the purpose of the DIMTOH system variable in AutoCAD dimensioning?
- Controls whether text is placed outside the extension lines when it does not fit
- Sets the text offset height from the dimension line
- Toggles horizontal text alignment in oblique dimensions (Correct answer)
- Determines text override handling
Correct answer: Toggles horizontal text alignment in oblique dimensions
DIMTOH (Dimension Text Outside Horizontal) controls whether text placed outside the extension lines is forced to horizontal orientation.
Question 6: Which command is used to update existing dimensions to match the current dimension style?
- DIMUPDATE
- DIMSTYLE with Apply option (Correct answer)
- -DIMSTYLE with Apply
- REGEN
Correct answer: DIMSTYLE with Apply option
In the DIMSTYLE Manager dialog, selecting a style and clicking 'Set Current' then using the 'Apply to Selected Dimensions' or Apply option updates existing dimensions to the current style.
Question 7: What effect does setting DIMSOXD to ON have on a dimension?
- Suppresses arrowheads when they are placed outside extension lines (Correct answer)
- Suppresses the first extension line
- Forces text outside the dimension line
- Enables oblique extension lines
Correct answer: Suppresses arrowheads when they are placed outside extension lines
DIMSOXD (Suppress Outside Extension Dimension) suppresses the arrowheads when they must be placed outside the extension lines due to insufficient space.
