I am a bit confused why 2 points can define a plane, and it doesnt start from the origin point… why …
Much appreciate
Richard
Two points can determine a plane if one of them is assumed to be the the origin and the other a normal vector. However, it is not a UNIQUE plane, as there are an infinite number of parallel planes that can be rotated around the normal vector. In the case of Grasshopper, I think it chooses one arbitrary plane amongst those that has its X-Axis is parallel to one of the principal axes…
