TestZBiasFactor Resets after Save

G’day Everyone,

Is TestZBiasFactor supposed to reset after a save?

We have a set of complex models exported from microstation. They’re exported as iges and mostly import reasonably well. In shaded display mode one of the models displays x-ray like lines from the interior objects through the exterior objects. Applying TestZBiasFactor of 32 seems to fix it…until the model is saved at which point the x-ray like lines reappear.

This is really early days for the project so no screenshots until we’ve got a rock-solid contract, sorry.

Thoughts?

regards,
Nick.

edit - Rhino 5

Hi Nick - can you possibly send us that iges file? tech@mcneel.com… to my attention.

thanks,

-Pascal
