Bye-bye.
I began to dwell in the forum on reporting of other users in the ptc community, then I saw your request and, better late than ever, I did not resist and had to register.
pdfs with searchable text are frequently requested by our customers.
We also have no chance to get out directly with this drafting/modeling output and we must pass first from the dwg format.
while having some licenses of autocad 2014, we never managed to get pdf with searchable text, but the result was achieved using nanocad (https://nanocad.com/products/nanocad/download), free program.
serves, of course, an appropriate configuration of the dxfdwg.con file to ensure the proportions of the converted text, but the final result is very satisfactory.
Good job
