AutoCAD Dimensioning and Annotation 5 â Questions and Answers
Question 1: What does the DIMSPACE command do to a group of parallel linear or angular dimensions?
- Evenly spaces selected parallel dimensions at a specified or automatic distance apart (Correct answer)
- Sets the text spacing within a single dimension
- Adjusts the space between the extension line origin and the object
- Spaces arrowheads uniformly
Correct answer: Evenly spaces selected parallel dimensions at a specified or automatic distance apart
DIMSPACE adjusts the spacing between stacked parallel linear or angular dimensions to a uniform value, cleaning up uneven dimension placement.
Question 2: In the TOLERANCE command dialog, what does the 'Datum Identifier' field create?
- A datum feature symbol (triangle with letter) referencing a datum plane or feature (Correct answer)
- An ID tag for the tolerance frame in the database
- A layer name for the tolerance annotation
- A reference to a datum point coordinate
Correct answer: A datum feature symbol (triangle with letter) referencing a datum plane or feature
The Datum Identifier field in the TOLERANCE dialog creates a datum feature symbolâthe boxed letter triangle used in GD&T to identify a datum reference.
Question 3: Which system variable suppresses the second extension line in a linear dimension?
- DIMSE2 (Correct answer)
- DIMSD2
- DIMSUP2
- DIMEXT2
Correct answer: DIMSE2
DIMSE2 (Dimension Suppress Extension 2) suppresses the second extension line of a linear dimension when set to On (1).
Question 4: What is the difference between DIMRADIUS and DIMJOGGED when dimensioning arcs?
- DIMJOGGED adds a jogged (zigzag) break symbol to the radius line, used when the center is outside the drawing area (Correct answer)
- DIMJOGGED measures the arc length while DIMRADIUS measures the radius
- DIMRADIUS is for full circles only; DIMJOGGED is for arcs only
- DIMJOGGED creates a diameter callout; DIMRADIUS creates a radius callout
Correct answer: DIMJOGGED adds a jogged (zigzag) break symbol to the radius line, used when the center is outside the drawing area
DIMJOGGED creates a jogged radius dimension with a zigzag break line, allowing the center point to be placed at a convenient location when the true center falls far outside the view.
Question 5: When you define a dimension style as 'annotative,' what automatic behavior does AutoCAD provide?
- Dimensions created with that style display at the correct plotted size in each viewport based on its annotation scale (Correct answer)
- Dimensions are automatically numbered in sequence
- Dimension text is linked to a database field
- Dimension style is shared across all open drawings automatically
Correct answer: Dimensions created with that style display at the correct plotted size in each viewport based on its annotation scale
Annotative dimension styles scale the dimension components automatically in each layout viewport to match the viewport's annotation scale, ensuring consistent plotted sizes.
Question 6: What is the function of the DIMCENTER command?
- Draws center mark crosshairs or a centerline at the center of a selected arc or circle (Correct answer)
- Sets the center justification of dimension text
- Moves a dimension to the center of its extension lines
- Creates a center point dimension for a hole
Correct answer: Draws center mark crosshairs or a centerline at the center of a selected arc or circle
DIMCENTER places a center mark (cross) or centerlines at the center of an arc or circle, controlled by the DIMCEN system variable value.
Question 7: If DIMTIX is set to On, what happens to dimension text placement?
- Text is forced inside the extension lines regardless of available space (Correct answer)
- Text is fixed to an external position above the dimension line
- Text is toggled to italic formatting
- Text index values are displayed instead of measurements
Correct answer: Text is forced inside the extension lines regardless of available space
DIMTIX (Dimension Text Inside eXtension lines) forces the dimension text to be placed between the extension lines even when there is insufficient space.
