AutoCAD Coordinate Systems & Navigation 1 — Questions and Answers
Question 1: What does WCS stand for in AutoCAD?
- Working Coordinate System
- World Coordinate System (Correct answer)
- Width Coordinate System
- Workspace Coordinate System
Correct answer: World Coordinate System
WCS (World Coordinate System) is the fixed, absolute coordinate system in AutoCAD from which all other coordinate systems are derived.
Question 2: When entering coordinates in the format "@3,4", what type of coordinate entry is being used?
- Absolute Cartesian
- Absolute Polar
- Relative Cartesian (Correct answer)
- Relative Polar
Correct answer: Relative Cartesian
The @ symbol indicates relative coordinates measured from the last point, and two comma-separated values indicate Cartesian (X,Y) format.
Question 3: Which function key toggles the coordinate display on the AutoCAD status bar?
- F1
- F6 (Correct answer)
- F8
- F10
Correct answer: F6
F6 toggles the coordinate display on the status bar between off, absolute, and relative polar coordinate modes.
Question 4: In AutoCAD, what polar coordinate entry would draw a line 5 units long at a 45-degree angle from the current point?
- @5,45
- @5<45 (Correct answer)
- 5<45
- #5<45
Correct answer: @5<45
Relative polar coordinates use the format @distance<angle, so @5<45 draws from the current point at 45 degrees for 5 units.
Question 5: What command is used to define or change a User Coordinate System in AutoCAD?
- COORD
- ORIGIN
- UCS (Correct answer)
- AXIS
Correct answer: UCS
The UCS command allows users to define, name, and manage User Coordinate Systems to simplify drawing in different orientations.
Question 6: When Dynamic Input is enabled, coordinate entry defaults to which format?
- Absolute Cartesian
- Absolute Polar
- Relative Cartesian (Correct answer)
- Relative Polar
Correct answer: Relative Cartesian
With Dynamic Input enabled, coordinate entry defaults to relative Cartesian (from the last point) unless overridden with # for absolute or < for polar.
Question 7: Which system variable controls the coordinate display format in the AutoCAD status bar?
- COORDS (Correct answer)
- COORDMODE
- DISPCOORD
- UNITCOORD
Correct answer: COORDS
The COORDS system variable controls coordinate display: 0=off, 1=absolute Cartesian, 2=distance and angle updated during moves.
