problems saving to a 3D PDF

I'm having issues with 3d PDFs too. No errors, but a blank PDF with a "?" icon...

Last time I tried to use this function was 5 months ago and we were still on 2016 but it worked fine. Now on 2017 and it's blank.

It's almost like GibbsCAM when you send a post processor in for a modification: It almost always comes back with the modification made but also has at least two NEW problems for the one modification. /sigh/

Just gave it a try and it worked okay.  Could it be the version of Adobe that you're using to open the file?  I'm using SWX 2017 SP3 and 2017 Adobe Acrobat Reader DC.

Have you compared the 3DPDF export options between the machines?  After reading about "lossy compression", it might have an effect.  Also, what is the file size of your exports?  As I recall, 3DPDF files are very large.  Not that your system timed out or anything but if the file size is very small it would suggest that the export gave up the ghost early in the process.

Are you exporting the same file on the different machines?  If the model has errors, I doubt the export would be clean.

Running out of straws to grasp so good luck!

What version of acrobat are you using (assuming you are using acrobat)?

3D PDF Error...Has anyone seen this before?

http://rockettcreative.com/parsing-error/a-3d-data-parsing-error.html   (this one claims that they have a repair tool.....I have NOT tested....talk to your IT department before using!!)

Maybe these won't help....but I just did a quick google search.

Most links say that version 9.3 is the culprit.

I would double check your Preferences in Adobe Reader.

Edit -> Preferences -> 3D & Multimedia category -> [√] Enable Playing of 3D content (located at the top).

I imagine that if this did work, and now does not, and that it works on other PCs, that your Reader Preferences may have changed. Someone may have changed it, or some settings may have been restored to defaults if you have uninstalled and reinstalled, or maybe even in an application update.

Had the same problem, this is how I solved it:

Go in the Adobe cache folder:

C:\Users\[user]\AppData\Local\Adobe\Acrobat

delete everything in it ( you could also rename it but the data will be created from scatch anyway).

I got the same problem for huge assembly model. but it works to generate its 3D pdf  for small parts .

I converted the big assembly into parts first and then generate its 3D pdf using the parts file.

it doesn't make sense for the Solidworks software though.
