PLCSVOUT-bgol (Export Polyline Coordinates to CSV)

Command Type: AutoLISP routine (works in AutoCAD, BricsCAD, ZWCAD and most AutoLISP-compatible CAD platforms)
Developed by: BGol Community, bgol.in

Inspired by the general concept of vertex-to-CSV export utilities used in CAD/survey drafting. This is an original, independently written routine, new file name, new command name, new source code, created so the CAD community has a free, editable, open-source alternative.

Overview

PCSV is a straightforward vertex-to-CSV export routine: select any polyline and export the X (Easting), Y (Northing), and Z (Elevation) coordinates of every vertex to a Comma Separated Values file, along with a sequential point number.

How to Use

1. Load PLCSVOUT-bgol.lsp into your CAD session (drag-and-drop the file onto the drawing window, or use the APPLOAD command).
2. Type PCSV at the command line and press Enter.
3. Select the polyline whose vertices you want to export.
4. Choose a location and file name for the .csv output (defaults to pntlist.csv).
5. A CSV file with a header row and one data row per vertex, point number, Easting, Northing, Elevation, is written to disk.

Why Use It

• Fast, direct export, no manual reading and typing of each vertex from Properties or the LIST command.
• Spreadsheet-ready, CSV output opens immediately in Excel or any spreadsheet tool, or feeds into other survey/GIS software.
• Simple and general, useful when a full-featured export tool with auto-numbering or chainage isn't necessary; just the raw coordinates.

Where to Use It

• Extracting Easting/Northing/Elevation data from any alignment or boundary polyline for use in a spreadsheet, report, or other software.
• Quick coordinate export tasks that don't need on-drawing vertex numbering.
• General-purpose CAD-to-spreadsheet coordinate handoff for survey or design polylines.

Notes

• Works on LWPOLYLINE entities. LWPOLYLINEs store a single Elevation property (not per-vertex Z), so every row shares that one elevation value, this matches how LWPOLYLINE geometry is actually stored.
• The CSV includes a header row (PointNo,Easting,Northing,Elevation) for easy import into spreadsheet tools.
• No new drawing entities are created, this is a read-only export.
• Source code is fully open, feel free to study, modify, and redistribute it under the same open, free-for-all spirit.
