====================================================

1/ Command :

• 1AR : Draw Single Arrow

• 0AR : Draw Single Arrow (Reverse)

2/ Description :

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

• Function: It creates a simple arrow shape using lines.

• Directions:

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

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

• 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.

• Compatibility: This is a dedicated CADian Lisp tool and works only within CADian.

3/ How to Use :

1. Type 1ar (for forward) or 0ar (for reverse) in the command line and press Enter.

2. (First run only) Enter the Scale Factor (e.g., 1).

3. Click the End Point of the line where you want the arrow.

4. Click a point to define the Direction.

5. The single-line arrow is automatically drawn.

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