Hi Martin, I can't seem to read that message until my forum registration there is approved or something.

But anyway, it was definitely a bug in MoI that MoI did not handle STEP files that used this style of unit system setting - that is fixed though with the above v2 patch for the v2 full release version, or with the v3 beta version.
