OK, I have been using this technique for over a year, several times a day, with the same software, never had this happen, and searched around a lot and it doesn't look like this is happening to anyone else either. I use Inventor Pro 2012, make an ipt. , make an idw. , then Export > To PDF and I use Nitro Pro 8 for my PDF's. Always works perfectly, Nitro allows some editing and options you can't get from Adobe, I like it. Until today. . . I followed this same procedure after making some revisions to a print. Export > To PDF > Overwrite Existing File. Nothing new there, I have done this thousands of times. Today, however, when the PDF window opened all my dimensions and text had just gone crazy, they deleted several characters, seemingly at random from everything. It's only letters and numbers, too. Not symbols, which I could expect if there was a font issue or something like what I've been reading about on here. The diameter and depth symbols are there, but, for example, there's a note that on the print reads "GREASE GROOVES Ø.25 (depth sym.)1/32" (D)". After conversion it reads " A Ø 2 (depth sym.) 1 32" (D)". I've gone through various settings and tried changing the way that Nitro converts text, and it never changes. When I go through the Print dialog and select Nitro, I get the same thing, except there's additional characters and symbols replaced by those rectangles of blank font. When I print straight from Inventor it works fine, when I preview the PDF export through Inventor it looks fine. Other files convert fine. It's just this one drawing that seems to be doing this. My views and graphics all come across normal and everything in my title block is OK, it seems like its just a random selection of characters that it doesn't want to carry over. I have spent way too much time on it already, and am wondering if anyone has seen anything like this before or has any suggestions I haven't already tried. I'll attach the PDF as it comes across, and the Inventor Drawing file for comparison. Thanks in advance.
