One of the Announced "Highlights" for OpenBuildings Designer CONNECT Edition, Update 5 (v10.05.00.49):
Structural Analytical modeling options are being discontinued
OpenBuildings Designer is discontinuing its native Structural Analytical modeling options in favor of Bentley's structural analysis software applications: RAM and STAAD. OpenBuildings Designer is integrated with these structural analysis applications via the Integrated Structural Model (ISM), which is designed to share structural engineering project information among modeling, analysis, design, drafting and detailing software applications.
Can anyone explain what this does mean in detail?
Will analytical axes / analytical surfaces not be generated for export to ISM by OBD anymore ?
Which are possible workflows transferring structural or geometrical data between OBD and structural analysis software applications? Especially I'm interested in workflows using non Bentley Structural Software like DLUBAL RFEM (includes German Code Standards), which can import structural geometry data (beams, structural walls and slabs) from .ism.dgn files).
Regards,
Michael
HI Michal,
please be assured this announcement is saying that ISM will be our preferred way forward. Pre Update 5 we had some tools that allowed a user to manually construct analytical features. These will be the ones affected by this announcement

i ASSUME THIS WILL NOT AFFECT THE ABILITY TO ADD THINGS LIKE COLUMNS AND SUCH AS WE DO BEFORE HANDING OVER TO STRUCTURAL?
WE DON'T HAVE A ENGINEER LOCALLY THAT DOES STRUCTURAL IN ABD. THEY USE RAM AND DO THIS IN MICROSTATION BUT NOT IN MODELING.

It would be good to provide a SIG session outlining how this would be done in STAAD or RAM using ISM.
Suspect that the analytical tools inherited from the Power Structural Modeler days have been discontinued because not many people were using it.
The other problem is that you would in theory need a STAAD license?
Maybe the way forward would be to help Dlubal write an ISM tool so that the RFEM user can assign the analytical properties to a model originating from OBD. Or better yet, transfer the analytical tools to Structural Synchronizer.
For my case using DLUBAL RFEM, there exists already an ISM-Import function. I conclude from Brendens answer, that this import-function will not be affected in any way by the discontinued OBD-functions.
The import-function of RFEM itself could use some improvement, though… For this I'm in contact with DLUBAL, but unluckily not many people are using it.
Michael,
Not sure, but if the analytical tools are removed from OBD, then the structural members you get on the RFEM side will not have the analytical information added. It will probably only have some tagging describing the elements as columns, beams etc.
Is that what you are expecting?
I expect that the announcement sounds worse than it actually is.
As Brenden said, only "manually construct analytical features" will be discontinued. Therefore I expect only functions of the section "Structural Analysis" of the Structural Ribbon will be affected by this. I actually don't use or need these functions for my workflow.
So hopefully everything will work as it is for me...
Correct, the "native" analytical tools in OpenBuildings Designer are those being deprecated. ISM export remains intact as do all 3D modeling tools like beams, columns, trusses, braces, etc., etc..
