Anyone have a free cogo lisp that would draw lines and arcs in the current UCS? I don't need points assigned, just the linework. I'll probably have to write my own, but I thought it's worth a shot asking here...
I have a radial tie lisp that worked in R14. Used to use it to enter points from the field book. It doesn't draw lines or anything just inserts points relative to a traverse line from the prompted for angles and distances.
But couldn't you just draw it realtime as quick as a lisp could do it?
Best book on AutoLisp programming...ever
For those interested in learning how to program in Lisp for AutoCAD, I note that you can still find copies of Maximizing AutoLisp - Complete Programming for AutoCAD on Amazon.
Written in 1992 for AutoCAD R12, this is hands down the best book you will find on learning how to write your own AutoLisp code. While perhaps a bit pricey for some at $90, it is a cornucopia of tips, tricks and examples from simple to complex.
And it still works...
Many lisp programs I wrote back when I bought this book just after it was published still work like a charm today. Almost everything I taught myself about lisp programming came from this book.
As a bonus for the Microsurvey users out there, Microsurvey has a number of lisp programming extensions you can take advantage of to automate many tasks with the code you can easily build using this book. Unfortunately, not in the embedded MSCAD version last I checked...but definitely in MSCAD 2010 and the beta of MSCAD 2013. I just tried it.

leaning lisp has been on my list
how much effort will it be?

The book I mention is an excellent starter for learning the basics of lisp programming with lots of code snippets you can use. it will provide all the tools and examples to write quite simple to complex functions.
I eventually learned how to build a complete COGO tool set, and a function to build sections and townships in the Alberta Township System. I started with zero lisp experience.

I can write the code pretty quick, but I'm swamped. I was hoping someone had something already available. Carlson is not UCS friendly. Entering bearing and distance in straight acad is a pain.
Thanks, all.
