2011-08-08 Thread Rob Spanton
Hey all, I've recently been playing around with designing footprints by describing a set of constraints that position features relative to each other. This is rather than specifying the absolute co-ordinates of every feature. I've written a small tool that allows this to be done. It pumps out

Re: gEDA-user: Wedana milestone reached

2011-08-08 Thread Павел Таранов
I understand... It is a result of symbol nature and Wedana drawing abilities. Symbols usually have their objects near 0:0, Wedana coordinate system is x=0:infinite, y=0:infinite (no negative values, like in gEDA) So just now there is no way to center symbol drawn on the left bottom.

I have been thinking about such a footprint editor as well. I think such a parametric sketcher is the way forward. At least it would make drawing footprints much more fun! It might be possible to use code from Sketchflat or pSketcher to obtain this functionality. http://cq.cx/sketchflat.pl
