Hallo,

does anybody of you know how to make a file created in Eagle 5 to be
readeable in Eagle 4.11? Ist there any way?

Regards!

Yes, export the lib, sch, and brd as script and then run the scripts on
the 4.11 version. Normally it works without problems, or with minor
problems, but normally the workaround to place the component in the
schematic is less time then adjusting the script. I don´t find the
german thread on that i have explained the procedure, but the problems
seems, that on the 5x version, the required ulp is missing, just use
that of the 4.x version.

Beitrag "Re: Eagle 5.2-Schaltplan fuer v4.16 speichern?" This is the thread
and
the message explaining the procedure, use babelfish translator.

If you have problems on making the conversion, write, or send me the
files to smt.mounter@gmail.com without the 1st dot.

I send you the files. I really don't understand the other thread- and
it's not because of the language :-( Isn't there any official
documentation from Cadsoft on how to do it? Eagle is a mess...
