Accepting contours

Calling the cycles
Selecting contours
The start and end point are specified for the contour line.
The start point and the direction are selected on a selected element. Beginning at the start
point, the automatic contour line takes all subsequent elements of a contour until there are no
following elements or intersections with other elements.
Note
If a contour includes more elements than can be processed, you will be offered the option of
transferring the contour to the program as pure G code.
This contour then can no longer be edited in the editor.
