4.1.3 Contours in the YZ Plane (Side View)
Starting point of contour
Y, Z: Starting point of the contour
P, α : Starting point of contour, polar (reference angle α : positive
Z axis)
Line segment
When entering a line, use the menu symbol to select the direction
and then assign dimensions. By selecting between ”tangential/
nontangential” you define the transition to the next contour
element.
Parameters
Y, Z: End point in Cartesian coordinates
Yi, Zi: Distance from starting point to end point in Y and Z
directions
P, α : End point in polar coordinates (reference angle α : positive Z
axis)
L: Length of line
W(A): Angle of line (reference: positive Z axis)
WV:
Angle to the preceding element
WN: Angle to the successor element
WV, WN:
■ The angle leads from the preceding/succeeding element
counterclockwise to the new element.
■ Arc as preceding/succeeding element: Angle to tangent.
