I’m starting to like inkscape more and more. It’s a shame that the soldermask doesnt have a layer in the PCB structure.
BTW i’m in the process of building this part. : pancake coil
I’m investigating if i can edit the gerberfiles manually, i’m sure it can be done. But then there isn’t a last option to check the files anymore. So as a temporary fix that may be an option though i hope i can customise the soldermask in fritzing one day.
i’m going slow, this is just a first idea, I need to simplify it much more, but i like how it looks right now.
BTW, With circles I wish there was a way to LOCK the Stroke width that would solve your question for 90%
