I have created a cube 10x10x10cm

I have exported as obj and imported in back with both Max import obj and create subD and both are imported just fine. right size.
weird but it works ...so now I have to look at Nvil3d import settings...

almost there..

As I tried other shapes came up with some weird measurements(50cm come in at 14.7cm)....used the import exact...came in at 100x smaller..
so I upped the export 100x in Nvil3d and it seems to open in Moi good.

Tnx!
