EN DI, Absolute Direction 23-29
DI, Absolute Direction
This command specifies the slope or direction at which characters are
drawn, independent of P1 and P2 settings. Use DI to change labeling
direction when you are labeling curves in line charts, schematic
drawings, blueprints, and survey boundaries.
DI run,rise [;]
or
DI [;]
The DI command updates the Carriage Return point to the current
location. While DI is in effect, with or without parameters, the label
direction is not affected by changes in the locations of P1 and P2.
However, the Define Variable Text Path (DV) command interacts
with the DI command (and DR), as explained later in this section.
z No Parameters — Defaults the label direction to absolute and
horizontal (parallel to X-axis). Equivalent to (DI1,0).
z Run or Cos θ — Specifies the X-component of the label
direction.
z Rise or Sin θ — Specify the Y-component of the label direction.
• Together, the parameters specify the slope and direction of the
label.
