It's kind of cute. It's more like a proof of concept, or minimal viable product, at this point. Bring it up to the level of Inkscape, so you can do most of the things .svg files can represent, and it will be useful.
(Inkscape is a great piece of free software, one of the few pieces of free graphics software on Linux that doesn't come from a command line mindset. Also runs on Windows and Mac.)
Inkscape is awesome. Unfortunately one of the things its used for _a lot_ is designing for a laser cutter which is _not_ it's strong point: it can't really do precise stuff like you can in Solidworks with dimensioning and relations. I'd love an OSS solution for vector drawing that has dimensioning and relations, if anyone has any suggestions I'd love to hear them.
True. Inkscape, unfortunately, doesn't really understand dimensions. Internally, it uses "px" as a unit, although SVG understands "mm" and "in". Corel Draw is more serious about dimensions and units, which is needed when you're talking to a laser cutter. SVG users have asked for the opposite feature: roundoff to pixel boundaries, instead of floating point coordinates.[1] SVG's internal representation is a text string of a number with a decimal point, but it's up to the program writing the file to decide how many digits to put after the decimal point. And, of course, you'll get rounding errors going back and forth from text representation to internal floating point representation.
FreeCAD, http://www.freecadweb.org
I do basically all my CAD in it. For 3d-print, laser and milling, roughly in that order. For laser/millling you can either work directly with parametric 2d ("Part Design"), or work in 3d and then export 2d outlines (my preferred way).
