• Automation: Quickly applies the same arrow block to multiple line ends via window　selection.

• Limitation: Works reliably on single line or polyline objects.

3/ How to Use :

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

2. Enter the existing Block Name to use as the arrow.

5. The specified block is　inserted at the endpoints of the　selected lines.
