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

1/ Command :

• CL4

2/ Description :
This tool draws a center line between two　selected points that extends slightly beyond the points themselves.

• Auto-Extension: Unlike a standard line drawn between two points, this center line is automatically lengthened outward from the points by a set distance (likely based on DIMSCALE or a fixed ratio).

• Layer Management: Automatically places the line on the CENTER layer, creating it if necessary.

• LTSCALE: Automatically adjusts the line type scale.

• Input: Requires two points to define the center line's position.

3/ How to Use :

1. Type cl4 in the command line and press Enter.

2. Click the First Point (PT1).

3. Click the Second Point (PT2).

4. A center line is drawn between the points, extending slightly past them on the CENTER layer.
