Lots of cad options is a good thing, just like having more than one option for operating systems is a good thing. One of the reasons I really like Intellicad, it may tend to keep Acad slightly more in line, but at the very least it provides many of us a viable cad option. In my own opinion I don't think that Intellicad an be ported to Linux due to its tight embedding into windows. However splitting the cad engine out and then writing different front ends does have possibilities. It would be a LOT of work. I really do hope they can pull it off, but I am afraid that it will be for commercial purposes and therefore will not be open source. I haven't been hanging around Linux sites a great deal, but I gather that a commercial program would not be warmly received. Is this a correct assumption? Oddly enough the one entitiy that I see which has enough juice to port a cad program to Linux is AutoDesk. By the way, I did not mean to imply that you or anyone else would suggest that my program effort was a waste of time. From a practical point of view however, who would want to write a word processor program with Star Office freely available. Speaking of Star Office, I had discussions a while back with Risto where we noted that the only module Star office lacked was a good 3D graphics program built in. It tied in nicely with the theme of the article you linked to last week. Andy
