I tried loading NCPlot in ubuntu today using the wine application and it seems to work, slightly buggy but fully functional. That was the main program that I was concerned with because it's the program I use most for 2D code creation. I'll give MeshCAM a try tomorrow and see how that one works.

Hi Kent, all, another example of a software similar to what you are developing is GNU Radio Companion. http://www.joshknows.com/grc Albeit it is from a totally unrelated field (digital radio and DSP), this software too deals with blocks, wires and so on. Moreover it generates python code

Hi Kent, all, I found the gnuradio stuff a while back, and put it in the 'cool graphing collection' with others. 1) what IS this idea called?, this gui connected block draggable zoomable concept called? i now its part of graph theory, but this is specialized, its in every eda and plumbing

I find the tool table editor box to be a bit counterintuitive. You need to press the write button, then close the editor, or you end up with several editor boxes in the background. Even if I press the write button and close the tool table the ppmc.tbl file gets written back to what it was when
