Tangent to preceding
element
When entering data for a contour element you can program the
transition to the preceding element as a tangent.
Tangent to
prec. elem.
îš¾ Press the "Tangent to prec. elem." softkey.
The angle to the preceding element α2 is set to 0°. The "tangential"
selection appears in the parameter input field.
Selecting a dialog
When entering data for a contour element, there may be two different
contour options, one of which you have to select.
Select
dialog
îš¾ Press the "Select dialog" softkey to switch between the two
different contour options.
The selected contour appears in the graphics window as a solid black
line and the alternative contour appears as a dashed green line.
