Hi, PaQ,

Thanks for the reply, but, that's because modo works in meters. So you have a one to one correlation. You could also just set both modo and MoI to no units. Then 1 unit in MoI equals one unit in modo.

But I was making a small item less than 50 mm high. I really wanted to work in millimetres. I can visualise that quite well. Michael has provided an answer to this problem with 'Scale on unit change'.

So, what I'm doing now is setting the units to metres in MoI after the modeling is done. MoI will scale my model accordingly before I export. But this has to be done through the options before exporting, and then put back again after exporting.

What I was asking is if Michael can make it so that it is done automatically during the export process :-)
