Does anyone know if Autodesk has any tools available to change text from English to Spanish or point me in the correct direction on how to do so?
None that I know of buit-in regardless of version. There might be third party apps available.
I am running 2013
I was looking more to take a complete set of drawings that was done in English and wondering if there was a tool to run to change them all to Spanish.
Ah! yes, it's called hiring a technical person in your field with the proper language skills (and more importantly, technical language skills) in the destination software.
The days of Star-Trek like universal perfect translators are not here: your resulting output would be the biggest joke the contractor will have ever seen. Sorry.
