Is there a way to draw my schematic symbol art in anything besides the built in symbol editor?Like, can I draw the symbol lines and arcs in inkscape then somehow get that geometry into a .sym file?
There are some python scripts out there but i don't know of an svg to symbol translator.
Example for such a python script (written by me, not yet merged into the official repo i think.)
And there is kipart. This allows you to create black box components from a csv file.
It doesn't have to be SVG --> symbol(.sym) conversion per se, but it would be nice to have any vector art format at all --> .sym
Is the vector art representation used inside a .sym file one-off?
It's more of an interpreted language and a very limited one at that, lines, arcs and text with no font selection
