Fritzing Custom Part SVG

Fritzing SVG Fix.txt

If you get an error importing your custom part SVG, here is the quick fix:

Basically Fritzing is looking for width and height attributes in the <svg /> 
tag, open the SVG in a texteditor and just add it manually. You can use 3rd 
and 4th parameter from the viewBox attribute you find in <svg>.
  
However the correct SVG Options in Illustrator (NOTE: that SVG Options prompt
appears only when you Save As...) would be as follows:

SVG Profiles: SVG Tiny 1.2
Fonts Type: SVG
Subsetting: None
Image Location: Link
Decimal Placements: 3
Encoding: UTF-8
(Ingnore the rest)

That's the trick! I hope it helps!
