Hello, my name is Bill and I just joined the forum because I find myself in need of assistance.
I've been usibg DeltaCAD for (basic drawings) several years now but this is the first time for something (for me) very complex. How do I draw a spiral? By definition... an arc with an increasing or decreasing radius.
I hope you can help.
Thanks in advance,
williamnj

i44troll,
Thanks so much for the rapid response. I can't tell you how badly this thing has been kicking my butt, I much prefer to solve things on my own but this was getting the best of me. Thanks again.
I had tried something similair using the elliptical arc but that left the connection between arc segments angular and choppy looking. Your solution works but apparently it works only on larger radius archs. I was trying for a smaller radius, say a half inch for the largest arch segment, but with the smaller radius segments the arch connections again looked angular and choppy.
I was able to sidestep this by making a larger radiused spiral and then scaling it down to the appropriate size.
Many thanks,
williamj
ps
please substitute arc for arch in the above

i44troll,
The "whole" project that I'm working on is conceptually new, and hopefully patentable. So without going into too much detail the spiral is to represent a spring that functions as a pawl working with a ratchet all contained within a small cylinder. So at this point the spiral is representational and precision isn't warrented.
many thanks for your help,
williamj

Gotcha!
My Brown & Sharpe micrometer set uses a spring as a pawl making it much more sensitive than the ratchet types.

AlwMVMO,
Thanks for jumpin' in.
And thanks for the hard work on the macro, now... if I just knew anything about macros.
Hmmmmm....
