Rh 06 render mode problem

Hello!
I have i problem in the rh06 render mode display-
i am adding 2 images - 1. shaded mode when the balustrade vertical elements are visible -
2. render mode where the display is incomplete - as if the elements disappear in their upper part,
i tried also on another computer as i thought it might be a screen card problem , but it didnt solve the problem.
is anyone familiar with that?
any suggestions?

contrejour :wink:

Your model is 3.1 million units from the origin. That screws up mesh display.

oh yeah,
Thanks, it helped
