After upgrading to 2016, certain hatch patterns are not being printed. Look at following example
In Inventor:
PDF file:
It looks like certain hatch patterns are not getting printed regardless of line weight, colour, etc.
Anyone had similar issue?! 
Certain hatch patterns not being printed
Are you printing to pdf or saving to pdf? Which ever one you are doing try the opposite. Also, try a different pdf creator like Dopdf or Cute pdf Writer
Or if you like something that was said and it was helpful, Kudos
Or change the Quality from Standard to High-Quality in the PDF options

Since the Product Design Suite 2016 has shipped yet I am unable to test. I didn't have any issues with the Beta version (but a lot can change from Beta to final release). Generally changing the Quality from Standard to High Quality Print solves most issues in either the Export File as: PDF solves the problem. I'm using the latest version of Adobe Acrobat DC on my system.

Blair, thanks for the reply.
As stated earlier, I doubt the issue is caused by PDF creation process because it exposes itself even in Print Preview stage.
These are outcome of PDF setting with different resolution as you suggested:
Normal:
High Quality:
As a workaround, I was hoping to open the drawing on my other machine which still has Inventor 2015 installed. Sadly, since I have once saved this drawign in 2016, it can no longer be opened in earlier versions complaining about imcompatibilty between databases. Any idea how I can revert it back to previous version at least to be able to open it in 2015 and send the drawing to client?!
Odd in deed, the only way to convert a 2016 file to 2015 is to export the IPT or IAM file to a neutral format such is STEP or IGES, import into 2015 and create a new IDW.
I have asked that this be forwarded on to Support to look at.

Thanks for the effourt.
UPDATE
----------------
It turned out that only ANSI patterns, out of following list, appear in Print Preview (hence PDF):
Any other pattern except ANSI ones will be simply ignored.
Hi! This is indeed wrong. I am able to reproduce it using PDF OUT and DWF OUT. I will follow up with development and see where the exact problem is and how to resolve it soon.
Many thanks!

I have also come across this problem. I found it when trying to plot a drawing and no hatching shows up. I did test exporting and printing to Adobe PDF and have the same issue. This needs to be addressed soon as we use custom hatch patterns in a lot of our drawings that need to be present in prints.
