- Set the base angle that specifies a direction for 0°. For example, surveyors normally set 0° as "up" on the page. This setting ensures the correct display of angle and distance for drawing lines; the display on the status bar updates according to the angle zero direction and the orientation.
- Select Clockwise to increase angles in a clockwise direction.
- Set the rotation angle, or click Select in graphics area
to set the rotation angle and second point in the graphics area. - Set the rotation angle, or click Select in graphics area

Unitless prevents the scaling of entities. If the units of a Block (or drawing) to be inserted differ from the units in Block units format, the Block is scaled. This insertion scale determines the ratio between the units in the source and the units in the target drawing.
