thanks for your quick reply Michael - however, this is just too weird for me :) - I fail to see how this is a better alternative to either rhino or sketchup when moving / copying objects relative to one another...??

Now it may be that I am just not getting it, and i am sure you have thought about all this stuff - but this is so easy in rhino that the answer seems to be just to do it there...

All want to do is simply copy a floor of a building vertically to a new location, inferenceing existing geometry, which doesnt intersect anywhere in the vertical path, but is at a correct height...so easy in rhino or sketchup, but seemingly very difficult in moi without building in construction lies etc...?
