For instance, what's the difference between these two files, apart from the fact that someone has taken the imperial version and changed the document units from inches to millimetres?
Libraries>Objects-Imperial>14_Stairs.mcd
Libraries>Objects-Metric>24_Stairs.mcd
Better yet. the default stairs are also imperial:
Defaults>Stairs>14_Stairs Imperial.mcd
Why don't metric users get default stairs that are sensible metric dimensions, such as 3000mm floor-floor, 250mm max going, 170mm max risers, 900mm wide, etc.? Why do we get lumped with imperial objects?
