I have just updated my adobe reader to 9.4.2 and I am regreting it already. I use 3D PDFs on a regular basis and the ones I have that worked perfectly fine in 9.4.1 now do not work. They come up with:
"A 3D Data Parsing Error has occured"
Does anyone know why this happens and particularly how to fix it, preferablly without going back to the older version of adobe reader.
i've got the same problem after updating to 9.402 this message appears and i cannot open the 3d scene.
I found this (http://forums.adobe.com/message/2537356#2537356) thread and this link in it (http://communities.bentley.com/communities/everything_else_community/f/289/p/47047/106414. aspx#106414).
hope that these can help you.
hey after trying a while i found a solution:
i created my u3d models via the adobe 3d reviewer (export --> u3d export). now i simply opened each model with the viewer and exported each again as u3d.
now it works
Do you have a test file that you can share?
