PlaneEquation

Returns the equation of a plane. The standard equation of a plane with a non-zero normal vector is as follows:

Ax + By + Cz + D = 0

Rhino.PlaneEquation (arrPlane)

arrPlane

Required. Array. The plane. The elements of a plane array are as follows:

Element	Description
0	Required. The plane's origin (3-D point).
1	Required. The plane's X axis direction (3-D vector).
2	Required. The plane's Y axis direction (3-D vector).
3	Optional. The plane's Z axis direction (3-D vector).

Array	An array containing four numbers that represent the coefficients of the equation, if successful.
Null	If not successful, or on error.
