6.7.3 Parameterizing contour elements
Function
In principle, input screens are handled according to the same
procedure already described for handling contour elements
STRAIGHT LINE, OBLIQUE LINE and CIRCLE.
To help you to program a contour, the following softkeys are also
available:
Tangent to preceding
element
Tangent
prev.
The "Tangent preced. elem." softkey presets the angle
α2 to a value
of 0
. The contour element has a tangential transition to the preceding
element, i.e. the angle to the preceding element (

degrees.
