Help Needed: AutoCAD LISP – Point Numbering with Block Attributes

javeed4teen — Sat, 16 Aug 2025 04:53:39 GMT

Hello everyone,

I’ve prepared a LISP with some help, and I need an upgrade. Here’s what the current LISP does:

Takes the vertices of a selected polyline
Places a point at each vertex
Places a number (text) near each point
Prompts the user for text height and text offset

The problem is:

If two vertices are very close, it’s hard to tell which number belongs to which point.
I tried converting the point + number into a block with an attribute, so the number increments automatically for each vertex.
I want a solution where selecting the block selects both the point and the number, making it easy to see which number belongs to which point.

I’ve tried multiple approaches, but I keep running into issues:

Errors when creating the block programmatically
Attribute numbers not updating correctly
Blocks appearing larger than expected or containing the polyline itself

I’m looking for a robust solution where:

The block contains both the point and a number attribute
The number increments sequentially across all vertices and polylines
The text offset is customizable
A CSV with number, X, Y coordinates is exported

Has anyone successfully implemented something like this in AutoCAD using LISP? Any tips, example code, or guidance would be greatly appreciated.

Thanks in advance!

Have a look at this makes a block either a square or a circle and numbers them. Just add the "point" at the insertion point. Or use a "X". look at teh way the pline and circle are added.
