The gTRANS command from the CADstudio TRANS AutoCAD add-on utility has 9 predefined language pairs to translate from-to. So it can automatically translate DWG drawing texts from or to: English, German, Czech, Italian, French, Spanish, Portuguese, Slovak and Finnish.
But you can easily add (or change) your own language - any language supported by Google Translate and based on 8-bit coding. As advised in the TRANS readme, use the gTrans_langlist LISP variable to define the language pairs. E.g.:
(setq gTrans_langlist '(("en" . "English")("nl" . "Nederlands")("no" . "Norsk")("sl" . "Slovenski") ))
will limit the language selection to English, Dutch, Norwegian and Slovenian.
Then just pick the texts to translate automatically (and of course then fix the imperfections of the machine translation).
