New version 4.???/Autocad 2004
Will the new version 4.??? currently in beta testing be compatible with AutoCad 2004 rumored to be coming out?

I believe you are answering your own question. It cannot be expected to be compatible when Autocad 2004 has not even been released yet. It is up to the ODA to provide support first, before Intellcad can.

Al, Yes I did in a way. The posts I've seen indicate that the ODA will have it's work cut out for them. What really concerns me is if the ODA will attempt to keep compatibility and will they be able to keep compatibility without copyright infringement?

I agree with your concerns. On the bright side, if Autodesk can legally lock down the dwg format using strong encryption or copyright protection measures, why have they not done it a long time ago? Considering all the non-autodesk products in need of dwg I/O support, cutting them off would compromise the dwg's status as an industry standard file format.

I believe there are at least two issues. Autocad 2004 will have built in the possibility to encrypt files so only your recipient can access them, when using a password. This is a mechanism that is available and can be supported by anyone. A word document has it too.Then there is the file format. It has data compression built in. Data compression is not the same as encryption. If any additional encryption is used, we'll see it as it is released.regards, sander, bricscad

From the News section at the OpenDwg Alliance homepage:PHOENIX, AZ, April 1, 2003 The OpenDWG Alliance, a non-profit industry consortium committed to promoting open industry-standard formats for the exchange of CAD data, today announced that it has been working to support the newly-released AutoCAD® 2004 drawing (DWG) file format in its DWGdirect program libraries. Progress by the OpenDWG team in support of this has been slowed because of technical challenges introduced with the new DWG file format.In this case, we actually went to Autodesk, and asked them for assistance. Despite some friendly conversations and the initial promise of assistance, they have so far declined to provide any information on their data encoding algorithms.We are being very cautious about recommending AutoCAD 2004 in any project where long-term access to DWG data is critical, stated Yares. Until we solve the underlying data encryption and compression problems with complete certainty, new DWG files could present ongoing problems for interoperability, compatibility and usability of legacy data.

For those who want to dig into this,here are the public messages of opendwg, who enable us to access dwg format. It's technical.http://www.opendwg.org/News/weblog.htmhttp://www.opendwg.org/News/040103.htmregards, sander, bricscad
