4. Do one of the following to specify the length: Enter the length of the line, for example 25.

Precision in Specifying Point Locations
- Open object snap , to snap to locations on objects
- Use Orthogonal locking, Ortho Mode (F8), to constrain cursor movement to the horizontal and vertical directions
- Use angle overrides to lock the cursor to a specified angle
- Enter Specific Coordinates of point, for example 10,8
- Using a Relative Coordinate, for example @10,8
- Enter line length and angle, for example @100<45
