I now have another issue with fonts, see screenshot below (viewed with latest Acrobat Reader DC). The dots are where the font have gone missing (Noto Sans). I emailed the PDF (drawing) to an end user for reviewing and he has the same issue. If I use a different PDF viewer (for example, SumatraPDF) then the font displays correctly. If I use Noto Sans in Word and export as a PDF, then I can see the font in Acrobat Reader DC. If I export the drawing file using Microsoft PDF publisher, then I can see the fonts in Acrobat Reader DC (but then the shading is all crappy again - see another post of mine). So, it would appear that the HOOPS PDF publisher is not embedding the fonts correctly? Can someone else perhaps test this using Noto Sans and the HOOPS PDF publisher? In the meantime I'll just change my dimension styles back to Arial, because that does work with HOOPS. I know people are going to ask why I use Noto Sans? It is slightly more compact than Arial and I prefer the look of the numbers. I guess it's not a big deal, but it should also just work.
