eagle2freecad.py does not appear to be up on your github. At least I can&#039;t find it. Sorry if there&#039;s something really simple I&#039;m missing.

		<description><![CDATA[Hi,
If you can do that with the XML data, you can do the same directly in Eagle using an ULP(script in the IDE).
About the color, there is a path  which use colors in Eagle, but this is not really appropriate for coloring parts in your 3D models.. :/
I&#039;m think it&#039;s interesting for people who don&#039;t have Eagle ;-)
