AutoCAD Break — split polyline AutoCAD using Break at Point and Break_Pline.FAS.
Primary Keyword: AutoCAD Break | Secondary Keyword: split polyline AutoCAD, Break at Point, Break_Pline.FAS

Ever wished you could edit or split objects in AutoCAD instantly—without repeating the same steps again and again? In this tutorial, we explore the Break command, Break at Point trick, and a powerful automation tool that breaks polylines at every intersection automatically.

First, the Break command: type BR, pick your line or arc, and choose two points to remove a segment—or a single point to split it.

Next, the hidden gem: Break at Point. Select your polyline, click the location, and when asked for the second point, type @. AutoCAD instantly splits your polyline into two parts.

But when you have many intersections, repeating Break becomes slow. Enter Break_Pline.FAS — an AutoLISP program that breaks ALL selected polylines at EVERY intersection automatically.

Steps:
1) Download Break_Pline.FAS
2) Load with APPLOAD
3) Type Br_Pl
4) Select polylines
5) AutoCAD breaks them and organizes output on a ‘Broken_Lines’ layer

Perfect for users handling complex networks, utility layouts, or heavy polyline drawings.
