BC MOF used to (still do?) do all of their FC maps in MicroStation.  I'm not a 
MicroStation user, but my guess would be that it's a workaround for the common 
offset applied to these maps.  
 
We used to subtract 5 million from our Northings when working in UTM with PC 
Arc/Info so that we wouldn't lose sub-meter resolution with single-precision 
coverages.  I think that Microstation had a similar limitation.
 
There's really no such thing as BC UTM, unless someone was taking the central 
zone (10) and stretching it both ways or something.  I hate to think about the 
distortion if that was done though :)

Subject: Re: [fme] DGN Seed Files


Hello Carly,
Here are the answers, though not from the HORSE's mouth:
 
MicroStation has inbuilt unit settings for the dgn file called as working units.
Depending on the working units the features are coordinates are read in M, FT , 
Degrees and so on.
 
FME  has a setting to either read in Master, Sub or UOR (Units of Resolution)
 
"ft"- Seed file for units in Feet
"m"  - Seed file for units in Meter (Metric)
"II" - Degree ,Minutes
 
"bcutm" - Not sure about this one.
 
Additionally the seed file ending with _v8 mean that dgn files written using 
this seed file will be in V8 format.
 
HTH
Happy FME-ing

        Hello :)
        
        Does anybody what the "ft", "m", "II" and "bcutm" refers to in the 
        names of the standard list of seed files in \FME\design? 
        
        I understand the seed files are defined by 2D, 3D, v7 and v8 - however 
        cannot find what the other alternatives listed above refer to
        
        Many Thanks,
        Carly
