AutoCAD 1 Questions and Answers

How do you specify a point using absolute coordinates in AutoCAD?
✔✔To specify a point using absolute coordinates, type the coordinates in the format X,Y,Z
directly into the command line or prompt. For example, entering `10,20` places a point at 10
units along the X-axis and 20 units along the Y-axis from the origin.
What is the purpose of relative coordinates, and how are they used in AutoCAD?
✔✔Relative coordinates specify a point's location based on the last point entered. Use the `@`
symbol followed by the relative X and Y coordinates (e.g., `@5,10`) to place a point 5 units to
the right and 10 units up from the last point.
How can you use polar coordinates to place a point at a specific angle and distance?
✔✔Polar coordinates define a point by specifying an angle and distance from the last point.
Enter the coordinates in the format `distance<angle` (e.g., `15<30`), where 15 is the distance and
30 is the angle in degrees.
What is the difference between Cartesian and polar coordinates in AutoCAD?

, ✔✔Cartesian coordinates use X and Y values to specify a point's location on a grid, while polar
coordinates use a distance and angle from a reference point. Cartesian coordinates are used for
precise positioning along axes, while polar coordinates are useful for drawing arcs and circles.
How do you use the OFFSET command to create parallel lines at specific distances?
✔✔To create parallel lines using the OFFSET command, select the line to offset, enter the
desired distance, and place the parallel line. This method ensures lines remain equidistant from
the original.
What is the role of object snaps (OSNAP) in accurately locating points in AutoCAD?
✔✔Object snaps (OSNAP) allow you to precisely locate points on existing objects, such as
endpoints, midpoints, and intersections. Activate OSNAP to ensure accurate placement and
alignment by snapping to specific points on objects.
How can you use the UCS command to change the coordinate system origin and orientation?
✔✔The UCS (User Coordinate System) command allows you to redefine the origin and
orientation of the coordinate system. Use UCS to set a new origin or rotate the coordinate system
to align with specific drawing elements for easier modeling.
What does the Z-coordinate represent, and how is it used in 3D modeling?
