algorithmic modeling for Rhino
Hi All,
I have a question regarding Rhinos Plane normal to curve function.
When creating a plane normal to curve it uses the tangent vector at a specified point for the Z axis of the plane. By default how is the X an Y axis then calculated in rhino?
Thanks !

That is the million dollar question. I have seen numerous discussions along those lines here in the forums but have yet to see a definitive answer. You can even use different plane generating components that on the face of it have the same inputs and criteria yet yield different results.
I think this was the most recent incarnation: http://www.grasshopper3d.com/forum/topics/about-pframes?
Hi Danny,
Thanks for the reply.
Yes it seems that there is not a clear answer here.
Its an important one to understand clearly as in the Design to Production pipeline this has quite an impact on how you generate and extract information from the models.
I have a feeling this might be some sort of mathematical logic:
