AutoCAD Divide Measure — split polyline AutoCAD using built‑in tools and AutoLISP.
Primary Keyword: AutoCAD Divide Measure | Secondary Keyword: split polyline AutoCAD, AutoLISP break polyline, Segment.LSP
Tired of AutoCAD only marking points when you actually want your polyline split? In this tutorial we explore DIVIDE, MEASURE, PDMODE and finally a powerful AutoLISP routine that breaks a polyline into real segments with labels and a dedicated layer.
We begin with DIVIDE — AutoCAD places 9 points when dividing a 5,000‑meter polyline into 10 parts, but the polyline remains a single object. Next we adjust point visibility using PDMODE and PDSIZE so Divide/Measure points become clear. MEASURE allows placing points at exact distances like 500 and 2600 along curved or multi‑vertex polylines.
But both commands only mark locations. They never split the polyline.
To actually break the line, we load Segment.LSP using APPLOAD. Running Seg_Pl lets you enter intervals such as 500m, and the routine automatically splits the polyline into pieces, labels each segment, and places them on a new layer called Broken_Line.
Divide & Measure = points only. AutoLISP = real break + labels + organized output.
Perfect for surveying, utilities, road design, profiles and any interval‑based work.
