V8i Compatibility

I have been searching all over to find out how far back someone can create a dgn that will work seemlessly with SS3

You should be able to open a DGN file created on a VAX in 1985.  The IGDS (V7 DGN) format didn't, and hasn't, changed.  Intergraph published the IGDS format in 1988.

Right now our guide say 95 but I am certain that won't work

Why are you certain?  Have you a DGN file that won't open with MicroStation V8?

See the History of MicroStation.

It was more of an assumption.  I just figure with modeling features that the file from 95 would be missing some features.  Thank you though.

I have data from1988 and can open it.  my zenith with a 80286 didn't have 3d....

My company is going through a revamp of our guideline on how we recieve drawings and models from our vendors.  As of right now we are using V8i SS3.  I have been searching all over to find out how far back someone can create a dgn that will work seemlessly with SS3.  Right now our guide say 95 but I am certain that won't work.  Does anyone know?  Thanks in advance.

Because its not autocad you can open all and any stored old dgn files irrespective of the version  with the current version of microstation..

The only exception is a VAX or Unix format storage material ie formated disc with unix dgn needs to be converted to MS dos format but the dgn is still dgn

just MS dos cant read the disc physical format not the data... I used to do this alot  in late 80s export VAX main frame unix dgn files to pc msdos  floppies all the time....

those exported floppy 5.25" disks  would still be dgns that mstn could read today only problem is those old disks probably badly deteriated after 25-30 years and where you going to get a 5.25 " drive to load on these days? that works on modern pc hardware....

Here is a sample file from 1988 (pre V8) (the sample was actually from 1983 taken thru the change-over from Intergraph VAX to DOS Bentley)

Only 2 real versions of MicroStation V8- (pre V8 aka V7) and V8+ All M-Sta. has done is taken limitations away and added feature's
