Model unit issue

[micvan]

Hi everyone,
I have a problem to import my model in KS5...I don't know why but when I import my model ( with origin dimension setted) created in  mm with sketchup, KS reads model in inches; so I change unit in mm and try to move a box from A to B to 1000 mm but don't move it to 1000 mm. How can I resolve this?

   Thanks
