Honeybee[+] does not yet support curved brep geometries and so you have two options for these types of situations:
- Planarize your geometry using methods like what @OmidmRashidi has posted.
- Mesh the geometry yourself with native GH components and plug the resulting mesh into the HBSurface component.
The second one might be best for daylight simulations since increasing the number of mesh faces using Rhino’s automated meshing won’t drastically increase the calculation time. However, when we eventually add in energy modeling capabilities into HB[+], you will probably want to do option 1. since using Rhino’s automated meshing can create a lot of surfaces that will greatly increase the calculation time.
I think that we will eventually build option 2 into the component so that you don’t always have to mesh it yourself if you do not want to.
