Problem with running Viper with closed volume created by planar surfaces

Hi Jon and everyone,

I am having problems getting Viper to run with the following volumes I've created. The volumes are all closed with planar surfaces but create in different ways in Rhino. The reason for this is that I wanted to control the form of the volume via the locations of the points with sliders in Grasshopper.

Are there certain rules to follow when creating volumes? I have tried 3 options shown below and included the files for your reference.

I am using Rhino 4 SR9 with GH 080063 and DIVA 1.902.

Hope to hear from you guys.

Hi Siong,

Looks like Viper's planarity test is using too strict a tolerance. I'll fix this in the next release, but in the meantime, change your Rhino units to meters and it should be fine.
