By combining two freeware tools by CAD Studio - VerticesBlk and InsertC/BlockC - you can easily annotate all vertices of a selected polyline with numbers and coordinates.
You will need an annotation block with one (or first) attribute for the future number (vertex ID) and optional other attributes - e.g. for coordinates. An example of such block can be downloaded from the Catalog - see VertID:
Now import this block into your drawing (Insert) and load (Appload) the two LISP utilities VerticesBlk and InsertC (see www.cadstudio.cz/download).
First start the VerticesBlk command to insert the VertID block to all vertices of your polyline. Then start the BlockC command to renumber the labels with a series of incrementing numbers.
