Programming contours

Function
The free contour programming allows you to create simple or complex contours. You define
open or closed contours.
A contour comprises separate contour elements, whereby at least two and up to 250 elements
result in a defined contour. Radii, chamfers and tangential transitions are available as contour
transition elements.
The integrated contour calculator calculates the intersection points of the individual contour
elements taking into account the geometrical relationships, which allows you to enter
incompletely dimensioned elements.
You must always program the geometry of the contour before you program the technology.

Representation of the contour

G-code program
In the editor, the contour is represented in a program section using individual program blocks.
If you open an individual block, then the contour is opened.
The cycle represents a contour as a program block in the program. If you open this block, the
individual contour elements are listed symbolically and displayed in broken-line graphics.
Symbolic representation
The individual contour elements are represented by icons adjacent to the graphics window.
They appear in the order in which they were entered.
