The first, second and third axis of the local coordinate system of the surface are defined automatically. The first axis is according to the global coordinate system and lies with the second axis in the plane of the surface. The third axis is perpendicular to the plane of the surface.
Manual
The first axis of the local coordinate system of the surface is defined manually, the third axis is perpendicular to the plane of the surface and the second axis is determined automatically from the first and third axis.
AxisVectorx
Axis1_{x}

xcomponent of the vector defining the first axis of the surface.
AxisVectory
Axis1_{y}

ycomponent of the vector defining the first axis of the surface.
AxisVectorz

Plane definition

First points
The first three points of the surface are used to define the plane of the surface.
Best fit
All points of the surface are used to define the plane of the surface using the least squares method.
