Draw Single Arrow / Reverse Arrow

This tool draws a single-line arrow at the end of a line, which is often used in sequence drawings.

Directions:

1AR: Draws a forward arrow (pointing outward in the direction of the line).

0AR: Draws a reverse arrow (pointing inward towards the line).

Function

It creates a simple arrow shape using lines.

Naming

The command 1AR stands for "1 ARrow".

Scaling

Upon first use, it asks for an "Electrical Symbol Scale." If you enter 1, the arrow length is set to approximately 6mm to match standard symbol sizes.

The single-line arrow is automatically drawn.

1. 1.Type 1ar (for forward) or 0ar (for reverse) in the command line and press Enter.
2. 2.Click the End Point of the line where you want the arrow.
3. 3.Click a point to define the Direction.

To Change Size

If you need to change the arrow size later, type fac, press Enter, and input a new scale value.
