generative modeling for Rhino

angle of a planar surface (in Python)

Hi everybody!

I'm very new to Rhino Python, and this feels like a stupid question, so I apologize if the answer is obvious.

Is there an easy way to find the angle between a planar surface and a plane?  Or two planar surfaces?  The only solutions I could think of involve picking a point or vector on the surface and measuring its angle compared to some other point or vector, but that seems unnecessarily convoluted.  Any suggestions?

Thanks in advance.

Hi Adriana,

you'll need to get the normal vectors for both the surface and the plane (Z-Axis for the plane). The angle between these vectors equals the angle between the planes.

Ok.  Thank you very much!
