Understanding Cursor Modes in Autocad 2008

As the Command window aids you with messages, the cursor gives you clues about what to do.
Figure below illustrates the various modes of the cursor and gives a brief description of the role of each mode.




Take a moment to study this figure:

The Standard cursor tells you that AutoCAD is waiting for instructions. You can also edit objects by using grips when you see this cursor. Grips are squares that appear at endpoints and
at the midpoint of objects when they’re selected. (You might know them as workpoints from other graphics programs.)

The Point Selection cursor appears whenever AutoCAD expects point input. It can also appear in conjunction with a rubber-banding line. You can either click a point or enter a coordinate through the keyboard.

The Object Selection cursor tells you that you must select objects—either by clicking them or by using any of the object-selection options available.

The Osnap (object snap) marker appears along with the Point Selection cursor when you
invoke an osnap. Osnaps let you accurately select specific points on an object, such as endpoints
or midpoints.

The tracking vector appears when you use the Polar Tracking or Object Snap Tracking feature. Polar Tracking aids you in drawing orthogonal lines, and Object Snap Tracking helps you align a point in space relative to the geometry of existing objects. Object Snap Tracking works in conjunction with osnaps.
