Hi Gents, On this link, there are a number of demo programs, that can be of use to us. Don't be fooled by the fact they are "demo's". You need to sit trough the demonstration sitting, but afterwards some of these can be fully functional. As long as they are not for commercial use... http://www.hexagon.de/down_e.htm Cheers Patrick PS if you download any, and try them, send me a brief report on what they can and can't do, I will collate that, and put it out on the forum!
