ProgeCad is a nice piece of software. I don't use it as my primary drawing software. But when I use it and for what I use it (among other convertion of PDF drawings to dwg/dxf), then it works perfectly for me. And then - it can minimum the same as AutoCad, if not more and is much cheaper. So I can only recommend ProgeCad as an alternative to AutoCad and similar, especially for small / one-man companies, like mine. For example for architects who has a one-man company I think it would be an advantage to use ProgeCad. Other than that, the service and support is also very good and friendly.
