A few words about FidoCadJ...

FidoCadJ can export drawings in several graphical formats (PDF, EPS, SVG, PNG, JPG). CadSoft Eagle users will appreciate the FidoCadJLIB.lbr library, for importing schematics containing the most common symbols via a script created by FidoCadJ. LaTeX users will be happy about the possibility of including circuits in documents via the PGF/TikZ export.

Give us your feedback about FidoCadJ! The best thing to do is to write a review on Sourceforge, or participate to the forums.

A small FidoCadJ reader can be run as an applet in a browser window: FidoReadJ.
