Non-planar surfaces? Degenerate surfaces?


I’m getting an error in my run simulation component. It tells me, that my models consists of non-planar surfaces:

but there are no non-planar surfaces:

Though I’m getting pretty realistic results: 118 kWh/(sqm*a)…

Thanks very much!


Please upload your rhino and grasshooper file for further discussion.

Will do. Thanks, @minggangyin!

The rhino-file is empty because the geometry is paramatic. But it has the right settings, so it has to be used together.

Relaxing the tolerance in Rhino model fixes this issue. I set it to a cm (0.01).


thank you very much, @mostapha! I also found a little mistake in the gh. now its working fine. :slight_smile:

is cm the smallest dimension to work with honeybee?

No. It depends on your model. Being planar and nonplanar is relative to the tolerance in your model.
