You can use absolute or relative Cartesian (rectangular) coordinates to locate points when creating objects.

To use Cartesian coordinates to specify a point, enter an

Absolute coordinates are based on the UCS origin (0,0), which is the intersection of the

With dynamic input, you can specify absolute coordinates with the

The following example draws a line beginning at an

The line is located as follows:

Relative coordinates are based on the last point entered. Use relative coordinates when you know the location of a point in relation to the previous point.

To specify relative coordinates, precede the coordinate values with an @ sign. For example, entering

The following example draws the sides of a triangle. The first side is a line starting at the absolute coordinates -2,1 and ending at a point 5 units in the

To use Cartesian coordinates to specify a point, enter an

*X*value and a*Y*value separated by a comma*(X,Y)*. The*X*value is the positive or negative distance, in units, along the horizontal axis. The*Y*value is the positive or negative distance, in units, along the vertical axis.Absolute coordinates are based on the UCS origin (0,0), which is the intersection of the

*X*and*Y*axes. Use absolute coordinates when you know the precise*X*and*Y*values of the point.With dynamic input, you can specify absolute coordinates with the

*#*prefix. If you enter coordinates on the command line instead of in the tooltip, the*#*prefix is not used. For example, entering*#3,4*specifies a point 3 units along the*X*axis and 4 units along the*Y*axis from the UCS origin.The following example draws a line beginning at an

*X*value of -2, a*Y*value of 1, and an endpoint at 3,4. Enter the following in the tooltip:
