Join Lines

Join Lines brings the classic trim-and-extend operation from mechanical CAD to PCB design. Select two lines, run the tool, and click once near the corner where you want them to come together — Join Lines moves the nearest end of each line to the exact point where the two would cross, so they meet cleanly, with no gap and no overshoot.

It handles both cases automatically:

• Lines that fall short get extended until they meet.
• Lines that cross and overshoot get trimmed back to the crossing point.

It works on copper traces and on ordinary lines drawn on user (documentation) layers alike. There’s no dialog box and nothing to configure — the whole tool is one keystroke and one mouse click, which makes it ideal on a hotkey for cleaning up corners as fast as you can point at them.
