new software found

I am writing to inform myself that I have found three new softwares which might be very important for autoCAD use.
1.clicktoconvert- pdf batch creator from any image file(jpeg,tiff etc.)
2.pdf creator from autocad dwg file- which I got from www.autodwg.com (a dream software- wish I could get this in UWS! I converted thousands of file manually!)
3.Dwg creator from any PDF file!! from the same company.Will be useful to convert my early works into dwg drawing!!! (I hope making of a portfolio is getting closer).
