TyCAD - first created 22nd Feb 2005 - last modified 14th May 2005

---

I always wanted to write my own CAD system - I think I've been working on it for the best part of 5 years if not 10. I can't beat what's out-there already and it's only for fun anyway. I have and still use it as a test bed for various functions. Most of those functions I went onto implement as AutoCAD macros and more recently for TurboCAD and have hopes of releasing my own sheet metal application.

If I ever do finish it I'll post the updates here.
