- Tangent: The system draws a series of curves on
the surface. At all points along a given curve, the angle between the
local principal tangent to the surface and the Robot Z or W axis is constant. The
angular spacing between each curve is given by the Angle
Pitch value. The origins of the curves are the points on
the surface at which the Robot Z or W axis is normal.
- Normal: The system draws a series of curves on
the surface. At all points along a given curve, the angle between the
local normal to the surface and the Robot Z or W axis is constant. The
spacing between each curve represents a change in the angle of the local
normal given by the Angle Pitch value. The
origins of the curves are the points on the surface at which the Robot Z or W axis is normal.
