AutoCAD 2005 and earlier doesn’t have a way to dimension arc length, but Leonid Nemirovsky has come up with an AutoLISP routine that dimensions arc lengths very nicely. You can download it here.
Here’s the result:
Leonid has many, many more AutoLISP routines on his site, Better Than Nothing AutoLISP.
AutoCAD 2006 and later has this feature. Use the DIMARC command.

Many Thanks for the download, but I am a complete novice with such a file, how do I ‘insert’ or use the file in AutoCAD 2005 to create such a result?
Many Thanks
Mark

I am looking for a lsp to put in acad to dim arcs and a lsp to put text on an arc
Thanks. It’s good. But if you explain arc length function than it will be a better post.
