4.1.2 Contours in the XY Plane (Front and Back)
Starting point of contour
X, Y:
Starting point of the contour in Cartesian coordinates (X
radius diameter)
P,
α
:
Starting point of the contour in polar coordinates (reference
angle
α
: positive X axis)
Line segment
When entering a line, use the menu symbol to select the direction
and assign dimensions.
Parameters
X, Y:
End point in Cartesian coordinates (X radius dimension)
Xi, Yi: Distance from starting point to end point
P,
α
:
End point in polar coordinates (reference angle
α
: positive
X axis)
W(A): Angle of the line (for reference see illustration)
WV:
Angle of 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.
L:
Length of line
Tangential/nontangential: Specify the transition to the next contour
