/*

This script will reset the start and end positions of the selected arrows. The arrow will point to the center of the connected box and will have a gap of 8px from the box.

Tips: If you are drawing a flowchart, you can use Normalize Selected Arrows script to correct the position of the start and end points of the arrows, then use Elbow connectors script, and you will get the perfect connecting line!

If you want the connector to be next to the element, set it to 1.” } }; ea.setScriptSettings(settings); }
