List and describe the different coordinate entry methods available in AutoCAD?

Answer 1

AutoCAD Coordinate Entry Methods

Absolute Method: (X,Y)

Absolute Cartesian coordinates specify a point's exact distance from the origin point of

the coordinate system, which is represented as (0,0). The absolute X and Y coordinates

are signed numbers.

Relative Method: (@X,Y)

Relative Cartesian coordinates specify a point's exact distance from the last point that

was entered.

For example, typing @4,2 tells AutoCAD to locate a point that is four X units and two Y

units away from the last point entered. The X and Y relative coordinates are signed

numbers.

Direct distance entry is a shorthand relative coordinate entry method.

Polar Method: (@Distance

Polar coordinates specify a point's exact location by a distance and angle from the last

point that was entered. The distance is always positive and the angle is measured from the

positive X axis.

For example, typing @4<45 tells AutoCAD to locate a point that is four units away from

the current location and at an angle of 45 degrees from the horizontal.
