I have AOI and find to be non-intuitive in operation (what do I poke at now). I already have autocad 2000 and wonder if there are translators out there that will take the dxf file and put out a stl file. I need to use autocad for the engineering drawings for the master project I am working on. The list of tools I found was a good basis to evaluate from. I know that the site is going under a lot of flux as the project has yet to put out the 1.0 version. It just makes it harder when you find a resource on it and then to have it disappear. I do thank you all for the effort on the project.
