Hi, I'm Sebatian from Berlin. I have used Inkscape for a few years now and I have a project proposal on how to make Inkscape a full-blown electronics CAD tool with only few special-purpose additions. I have written some software before[1,2,3] and contributed to other open-source projects[4,5].
I have registered a blueprint with my proposal at [6]. The spec can be found in the wiki at [7]. Here is the overview from the blueprint: Currently there is no nice open source electronics CAD tool. The largest competitors are gEDA which I find awkward to use and KiCad which I find even more awkward to use. Since a schematics editor is not much more than a special-purpose flow graph editor and a PCB layout editor is in fact nothing but a somewhat crippled vector graphics editor with some special-purpose features added I think it is very promising to modify a general purpose vector graphics editor to support the few special-purpose functions additionally required by an electronics CAD tool.
Your comments are welcome :D Sebastian
