AutoCAD Dimensioning and Annotation 3 — Questions and Answers
Question 1: When annotating with MTEXT, which formatting code inserts a non-breaking space?
- \~ (Correct answer)
- \n
- \P
- \t
Correct answer: \~
In MTEXT, \~ inserts a non-breaking space that prevents line wrapping between two words.
Question 2: What is the function of the QDIM command in AutoCAD?
- Creates a quick series of baseline or continuous dimensions from selected objects (Correct answer)
- Applies a quick dimension style
- Queries dimension values without placing them
- Quickly deletes selected dimensions
Correct answer: Creates a quick series of baseline or continuous dimensions from selected objects
QDIM (Quick Dimension) rapidly creates baseline, continuous, staggered, ordinate, radius, or diameter dimensions from a selection set of objects.
Question 3: In ordinate dimensioning, what determines whether an X-datum or Y-datum dimension is created?
- The direction you move the cursor from the feature point when placing the leader endpoint (Correct answer)
- A setting in the dimension style
- The DIMORDT system variable value
- Whether you pick a horizontal or vertical edge
Correct answer: The direction you move the cursor from the feature point when placing the leader endpoint
AutoCAD determines X or Y ordinate automatically based on whether you move the cursor more horizontally (Y-datum) or more vertically (X-datum) from the feature location.
Question 4: Which MLEADER style property controls the shape of the landing line that connects the leader to the content?
- Landing gap
- Landing distance (none/straight/angle) (Correct answer)
- Leader type
- Content type
Correct answer: Landing distance (none/straight/angle)
The landing (also called the hook line) connection shape is set by the landing distance option in the MLEADER style, which can be set to none, straight, or angle.
Question 5: What does the DIMTEDIT command allow you to do that the Properties palette does not?
- Dynamically drag dimension text to a new position along the dimension line (Correct answer)
- Change the dimension style of selected dimensions
- Rotate the extension lines of a dimension
- Add tolerances to existing dimensions
Correct answer: Dynamically drag dimension text to a new position along the dimension line
DIMTEDIT lets you interactively drag and reposition dimension text along the dimension line in real time, which is more intuitive than typing a numeric offset in Properties.
Question 6: When you use DIMEDIT with the 'Oblique' option, what changes in the selected dimension?
- The extension lines are rotated to a specified angle (Correct answer)
- The dimension text is italicized
- The dimension line is moved to an oblique angle
- The arrowheads are replaced with oblique ticks
Correct answer: The extension lines are rotated to a specified angle
DIMEDIT Oblique rotates the extension lines of a linear dimension to a specified angle, useful for isometric or skewed drawings.
Question 7: What is the purpose of the DIMBREAK command in AutoCAD?
- Adds or removes a gap in a dimension or extension line where it crosses other geometry (Correct answer)
- Splits a long dimension into two shorter ones
- Breaks the associativity of a dimension
- Removes dimension text from a dimension
Correct answer: Adds or removes a gap in a dimension or extension line where it crosses other geometry
DIMBREAK adds a visible gap (break) in a dimension or extension line where it overlaps crossing objects, improving drawing clarity.
