Well, I tried the pdf to text thing on a tender drawing this afternoon.
My results were perhaps as you'd expect from a pdf that was probably not created using autocad.
I had a 20% chance of 'simplex' font being a match. Yay!
68% of the selection was not converted. Boo!
This was attempting to convert one word, from one line of text in an imported pdf.
For the record, it managed to recognise the bottom ring of two lower caste letter 'a' and created an mtext object with two 'o's rolled on their side.
It works a charm on pdf's I've created from my own autocad drawings, however using this feature on files received from somebody else (the time you need this to work) it doesn't seem to be worth a damn.
Anyone else tried this feature yet?
I'd be interested to know your results.
