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 *X* value and a *Y* value separated by a comma. 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 #

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.

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:

Command: **line**

From point: **-2,1**

To point: **3,4**

### Relative Coordinates #

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 **@3,4** specifies a point 3 units along the *X* axis and 4 units along the *Y* axis from the last point specified.

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 *X* direction and 0 units in the *Y* direction. The second side is a line starting at the endpoint of the first line and ending at a point 0 units in the *X* direction and 3 units in the *Y* direction. The final line segment uses relative coordinates to return to the starting point.

Command: **line**

From point: **-2,1**

To point: **@5,0**

To point: **@0,3**

To point: **@-5,-3**
