A user has sent me a collada export from another 3D product and it appears to be a collection of .dae files which make up a single model. Is there a way to import these as a group to create a single 3D PDF?
It depends what version of Acrobat you're using.
Acrobat itself cannot merge the source files together but it can load several different models into the same 3D viewport using JavaScript.
The result of any of the above will depend on the registration of the parts being correct (so a file containing a screw lines up with the other file containing the part with a hole). If they don't register then you'll need to position them all by hand in 3D Toolkit or 3D Reviewer.
