Wired thing in Rhino6 with Ladybug

We have established that these are 2 different issues and I will use this thread to continue looking into the clipping problem.

The issue.gh file that was posted here, exhibits a clipping problem on my system:

At a shallow angle, the mesh looks fine:

but at increasingly steep angles, the tops are increasingly more clipped:

Grasshopper, however, tells that the mesh delivered by the Ladybug_3D Chart component is invalid.

Questions:

  • Can somebody provide a simple definition that shows a clipping problem on a valid mesh?
  • @mostapha, is there anything that can be done to output a valid mesh from that component?

Thanks,
