Is there anything like this for Android? 3D PDF support would be the best solution for us.

It doesn't look like there is much out there for Android yet.

Maybe this one will support Android in the future, you might ask them about it:

I have been clamoring for 3dpdf on android as well.....there is nothing out there right now. I have requested this several times from Simlab since they do a 3dpdf exporter for ipad but they do not want to tackle the testing on so many of the android platforms to ensure it actually works....I would be happy if it just worked on my platform of course(ASUS Slider)
