Hi Sebastian and Kevin,

Let me try to answer your questions:
Adobe supports COLLADA via Photoshop Extended. It is the format for Google Earth. We don't see COLLADA as a manufacturing standard.

As far as the architecture is concerned, the concept of walk can be organized via Javascripts. As an example, you might go look at the Bentley Systems site to see some examples. We also have the walk tool in A3D. It fixes the camera in one point so it is somewhat limited. I hope this helps.

Franco, nice interview, and thanks for asking this really pertinent question:

"Different categories of users interact with 3D models in different ways. For example, when a user needs to look at the back of a 3D model, a mechanical designer rotates the 3D object while an architect moves around the object."

We've encountered this precise issue in our initial use of 3D PDF in architectural publishing.

I'd love to see it addressed in the standard format. I'm not quite clear on what Doug was saying his answer, on this specific issue of handling the two different viewing paradigms for the different application domains.



thanks for the in depth interview and the really interesting outlook! I've two questions, first regarding TTF: does Adobe still support the API TTF was providing for conversion? And second: Acrobat3D still lacks support for COLLADA, which is getting stronger every day, and is going to be supported as an open format not only by the gaming industry any longer.

Hi Antonio,

JT certainly has a lot of great capabilities including storage of precise B-Rep and tessellated geometric information and semantic product manufacturing information (PMI). Acrobat 3D v8 and the new rev PDF (v 1.7) has these same capabilities and adds several as well that are likely to be of interest to the engineering community. These features include (but are not limited to) geometric compression, digital signatures, and encryption. Acrobat 3D provides full support for reading JT files, so anyone with an investment in JT technology can push that information into PDF and gain the compression, encryption and digital certificate/signature capabilities of PDF while leveraging the free Adobe Reader.

There is also an XML channel in the PDF container so any type of structured data can be pushed into PDF files, e.g,. BOM. The APIs for the various PDF viewing clients including the free Reader enable PDF documents to communicate with backend systems like UGS's Teamcenter and send/receive information using XML and SOAP.

This can be very useful when communicating with suppliers who don't or can't have named seats in your PDM/PLM systems.

Hi, I would like to hear some comments on JT. Mostly in the automotive industry, JT is becoming a "de facto" standard when it comes to data exchange. I think that,at this time, JT is more targeted to the engineering world, while PDF is more targeted to the non-engineering world. I would like to hear some comments on the topic.
