#XYZ precision

Can anyone confirm that the XYZ coordinates in 3DSR4 are only to seven siginificant figures? We have a model which has ended up at with X values > 900000 and Z values > 450000, but is only about 5 units in extents (don't ask how, it wasn't me!). When this is scaled about its local axis to 10% the geometry gets corrupted as if it's got it's sums wrong. The only reason I can think of is if 3DS is working with single precision reals and we have hit the limits of its range. Are these limitations documented anywhere? Regards Tim Bates
