Michael,

I have a huge model (by now the Moi file is 230mb) and now a contractor asked me to change the origin / base point in the Drawing to something we can measure on site.

If I move ALL the Stuff I have at once my Computer keeps freezing or at least MoI is not doing anything anymore. (the RAM usage goes up to 1,8gb and nothing is happening anymore; there are lots of extrudes with the rail splines still there to allow easy manipulation so they have to be recalculated and I guess this just takes ages...)

As there are loads of things that I don't want to move by hand piece by piece - is there a command or tool that allows me to change the world Coordinate system to a point that I can define?

What you see is what you believe - so don't. (from an Amiga500 demo)
