TW2

[Steve Jepson]

Tell me about TW2.

How is it different than logging into a server with a program like Adobe Acrobat Connect Pro or similar?

[ares997]

I think the teamwork 2 server is getting misconstrued a little bit in the hearsay. TW2 or the Delta Server Technology is far different than acrobat connect because it's not a screen sharing software.

Basically the delta server/tw2 is a method for exchanging information in a way that typically requires the transmission of all the information to a from the location where the information resides.

The server is where the information is stored. It isn't as if their is a server farm some where where the information is going to be placed and then you go there. It is the system you have located the teamwork file.

Say if today you have a 20mb file, if you send/recieve that information you have to transmit all that information back and forth from the location of the server.

Now you only transmit the information that you have changed. And the likely hood that you have changed 20mb of informatin in a days worth of work is probably not highly likely.

So if you changed 100 walls and moved them 6" but nothing else the transmission of information only contains that information in the process of send\ receive. Which is a big saving for everyone and hardware.

It really is the most advanced thing that has ever happened to the industry to date.

I have worked with teams all over the world and the hardest part is teamworking across the world in the current version because you have to not only find a place to hook up to a fast connection, have your server connected to VPN accelerator, then you have to dissect the model in teamwork alone and then tell people to get it and what the get then take it back and open it and send and receive based on the number team members you have...

TW2 is the future and it's here.

Thanks for the info.
I wasn't thinking so much about the screen sharing aspects.

File synchronization vs file exchange seems to be the main idea.

Can we use this for other file synch needs or for only for certain types of files ?

Hi Steve,

It is not quite as described by ares997.

With a 20 MB TW file today, you would not be sending 20 MB back and forth anyway - only a much smaller draft TWC file - but the headaches involved in managing that from the central site are huge and well-known.

Watch all of the videos (the page expands to show even more videos on setup, etc) on TW2 to get a good overview. Whether it is the future or is step one towards the future, everyone will have to judge when they try it.

It is remarkably flexible because of (1) element level reservations, (2) no attributes or settings require exclusive access - but can be reserved like anything else, (3) the delta send/receive which makes the process not only very fast, but also enables remote access over the internet, (4) powerful user-capability assignment [see video screenshots], (5) dynamic messaging system, (6) ability to work with reserved or new elements 'offline' and S/R once reconnected to the network, (6) improved backup/restore capabilities, etc.

Also remarkable is that the server software can run on any machine, as seen in the videos - either someone's workstation in the case of a very small group, or dedicated machine, or an actual server.

Oh yeah, and as you can see in the videos, the clients and the server can be any mix of machines. In the video, they show a Dell/Windows server with iMac workstations, for example.

Commenting as I can only on what is public in the videos/etc so far, I can say that my only disappointment is that the server software module cannot run on a PPC Mac. I can see the logic for making ArchiCAD itself Intel Mac only, but there are so many powerful G5 Macs out there with multiple processors and lots of RAM that would be ideal BIM Server machines and cheap to pick up now that the most software is moving to Intel-only Macs - and it would have been a way for firms with a bunch of G5 Mac Pro's still in their inventory to make good use of them for another few years.

Cheers,
Karl

Just saw your second question. No, you cannot access the BIM Server, other than by logging into it via ArchiCAD (or the BIM Server Manager). It only dishes up ArchiCAD projects. It does not synchronize or offer any other services - a normal network server would be used for those things.

good info Karl. Thanks. I look forward to using it.

The Delta Server is something I heard about 5 years ago or so.

Is this a different Delta Server or just a new application for it?

http://delta-server.software.informer.com/5.0/

Lots of things out there called Delta Server. Lots of other BIM Servers too.

Bentley is already using 5-D BIM Hard Dollar.
Revit also has a BIM server plug-in.

Do we need Solibri for TW2 or is something like that built in?

If true, this really stinks. Our server is a G5 Mac Pro, and there's no reason to ditch it anytime soon. I guess we can run the BIM Server off one of our workstations, since we only have 2 or 3 people drafting.

How much of a performance hit does the server machine take?

[Steve Jepson]

Will Snow Leopard make it possible for you to use TW2 on the MAC ?

None at all. Both Karl and I just have it on our desktops. No separate servers.

The Greek letter Delta, as I'm sure you know, is the standard mathematical / physics symbol to represent differential change. That is why it is seen in so many places. (When it is time to change my oil, I write 'delta symbol' oil on my to-do list.)

What GS has done with the project database is what is a common concept in all databases - to transfer only the changes, ideally as light-weight as possible - including what part of the database is locked from other users during modification. With a typical database, this is relatively simple. With a complexly linked database such as an ArchiCAD project, I imagine this is quite complex, hence their patent application.

Yes, no relation to any other BIM Servers either. This is Graphisoft technology (using some off the shelf database components according to the article).

I have not been given an opportunity to use the Solibri model checker software, so cannot comment on it.
