Q20: Give two examples of symbols that automatically appear with some dimensions?
Ans: Two examples are:
a. Diameter symbol (): Appears with radial dimensions to indicate the diameter of a circle or arc.
b. Degree symbol (°): Appears with angular dimensions to denote the measurement in degrees.
Q21: What is one purpose of the AutoCAD gdt.shx font?
Ans: One purpose of the AutoCAD gdt.shx font is to provide special symbols and characters used in geometric dimensioning and tolerancing (GD&T) annotations.
Q22: Name the three dimensioning commands that provide linear dimensions for angled surfaces?
Ans: The three dimensioning commands are:
a. DIMANGULAR: Provides linear dimensions for angles.
b. DIMBASELINE: Provides linear dimensions for the baseline dimensioning system.
c. DIMCONTINUE: Provides linear dimensions for the continued dimensioning system.
Q23: Which command allows you to place a break symbol in a dimension line?
Ans: The BREAKLINE command allows you to place a break symbol in a dimension line to show that the dimension line does not extend through the break.
Q24: Name two commands used to dimension angles in degrees?
Ans:
Two commands used to dimension angles in degrees are:
a. DIMANGULAR: Dimensions the angle between two lines or edges.
b. DIMBASELINE: Dimensions the angle between a baseline and a line or edge.
Q25: Describe a way to specify an angle in degrees if the angle is greater than 180°?
Ans: To specify an angle greater than 180°, add the angle value to 180° and then use the "Override" option to display the correct angle measurement.
Q26: Define baseline dimensioning?
Ans: Baseline dimensioning is a dimensioning system in which dimensions are aligned using a common baseline, making it easier to read and interpret multiple dimensions.
Q27: Define direct dimensioning?
Ans: Direct dimensioning is a dimensioning system where dimensions are placed directly between the dimension lines without using a common baseline.
Q28: How do you place a baseline dimension from the origin of the previously drawn dimension?
Ans: To place a baseline dimension from the origin of the previously drawn dimension, use the "Continue" option of the DIMBASELINE command and snap to the desired extension line origin.
Q29: What is the conventional term for the type of dimensioning AutoCAD refers to as continued dimensioning?
Ans: The conventional term for the type of dimensioning AutoCAD refers to as continued dimensioning is "Continue" dimensioning.
Q30: Explain how to assign a layer other than the current layer to new dimension objects?
Ans: To assign a layer other than the current layer to new dimension objects, use the "DIMLAYER" system variable or the "Layer" option in the Dimension Style Manager to set the desired layer for dimension objects.
Q31: Which command other than DIM and DIMBASELINE creates baseline dimensions?
Ans: The "DIMCONTINUE" command creates baseline dimensions in AutoCAD.
Q32: Explain how to remove dimensions from the current set when you use the QDIM command?
Ans: To remove dimensions from the current set when using the QDIM command, select the dimensions you want to remove and press the "Remove" button in the Quick Dimensioning dialog box.
Q33: Name at least three options for dimensioning that are available through the QDIM command?
Ans: Three options for dimensioning available through the QDIM command are:
a. Baseline dimensions
b. Continue dimensions
c. Arc length dimensions
a. DIMANGULAR: Dimensions the angle between two lines or edges.
b. DIMBASELINE: Dimensions the angle between a baseline and a line or edge.
Q25: Describe a way to specify an angle in degrees if the angle is greater than 180°?
Ans: To specify an angle greater than 180°, add the angle value to 180° and then use the "Override" option to display the correct angle measurement.

Q28: How do you place a baseline dimension from the origin of the previously drawn dimension?
Ans: To place a baseline dimension from the origin of the previously drawn dimension, use the "Continue" option of the DIMBASELINE command and snap to the desired extension line origin.
Q29: What is the conventional term for the type of dimensioning AutoCAD refers to as continued dimensioning?
Ans: The conventional term for the type of dimensioning AutoCAD refers to as continued dimensioning is "Continue" dimensioning.
