Downloaded US Metric Dataset and installed for testing with SS4 - looks good so far
I like that it conforms to the US Imperial Dataset in structure eg Family&Part aligned to the new datagroup system
The range of doors and windows appears similar - but will need to place more to see differences (ANZ dataset tended to remove PAZ that didn't work)
The supplied Empty.dgn file has resolution described in feet - checked three seed files: Designseed, Drawingseed, Sheetseed have millimetres (the numbers are equivalent: 304800 per ft = 1000 per mm)
Design seed is set to accuracy of 0.12
Drawing seed is set to accuracy of 0
Sheet seed is set to accuracy of 0.1
Is there a reason for the difference?
For modelling does acccuracy affect unification glue? (we have one project in BArch set to 0.123456 mm)

Hi Ross, I'd imagine the "empty.dgn" file units is probably just an oversight.
In regards to accuracy, I don't know why each seed has a different setting, however, the unit display accuracy is simply for readout purposes and does not directly affect 3D modeling or unification. For example, if two walls were .0118mm apart and you were to measure that distance, you would see:
.0 @ one decimal
.01 @ two decimals
.012 @ three decimals
and of course .0118 at four decimals
But as long as the unification tolerance was set to something greater than .0118mm, those two walls should still unify.
