Question 1

What is the World Coordinate System (WCS) in AutoCAD?

Accepted Answer

The fixed, universal coordinate system that never moves or changes

Answer

The WCS is AutoCAD's fixed, absolute coordinate system — it never changes and serves as the universal reference frame from which all other coordinate systems (UCSs) are defined.

Question 2

Which object snap locates the center point of a circle, arc, or ellipse?

Accepted Answer

Center

Answer

The Center object snap snaps precisely to the center point of circles, arcs, and ellipses.

Question 3

What does pressing the TAB key do when entering coordinates in Dynamic Input mode?

Accepted Answer

Cycles the active input field between X, Y, and Z values

Answer

In Dynamic Input, Tab cycles the active text field among X, Y, and Z coordinate inputs, allowing you to specify each axis value independently.

Question 4

To which points on a circle does the QUADRANT object snap lock?

Accepted Answer

The 0°, 90°, 180°, and 270° positions on the circle relative to the UCS

Answer

The Quadrant snap locks to the four cardinal points of a circle or arc — 0° (right), 90° (top), 180° (left), and 270° (bottom) — measured relative to the current UCS.

Question 5

What is the FROM object snap override used for?

Accepted Answer

Specifying a new point at an offset distance from a chosen base snap point

Answer

The FROM override lets you snap to a known base point and then enter an offset, so AutoCAD places the actual point at that offset distance and direction from the base.
