i'd like to lay out a trace that will fit between a couple of pads with .100 mil spacing. the minimum wire size in fritzing won't quite fit. i was wondering if i could get away with opening the sketch in a text editor and changed all occurences of "wireExtras mils=24" to "wireExtras mils=8."
ok, tried it. looks like fritzing is displaying 8 mil traces, but with 24 mil blobs at all the bends in the trace. must experiment further...
The thinnest trace that's currently supported is 16mil. It looks like you've already used the popup labeled "width" available in the inspector to set the trace width, but at least if you set your wires to 16 mil, then the blobs might be that size instead of 24 after you hand-edit the sketch.
I'm not an expert at this, but if distances are too fine, you may get some unexpected electrical behavior. Also you will have to be sure that whoever prints the board can handle that level of accuracy.
i take it the circles are to cover any discontinuities or wierd jaggies where the traces bend. since the size survived my doctoring the file, somewhere in the xml there must be a memory of the trace width other than within the wireExtras tag. any suggestions?
The "blob" is generated without reference to the wire width--it is just the bendpoint handle. It will not appear in gerber export. If the handle (but not the rest of the trace) touches another part or trace, there is no actual electrical connection made.
sorry. had i not been falling asleep i could have generated a set of gerbers and resolved that one for myself. thanks for your patience.
