Professionally I'm a structural building engineer who spend most of the time with Autocad. Because I prefer to click 2 times rather than 200 I'm writing lisp routines to speed up and make my work comfy :). I started this blog to make public some of them. Also I treat the blog as diary where I'm writing resolves of problems which I faced during lisp development. It's handy to have them in one spot and may be helpful for others.
