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.
ShopTurn program
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 symbols adjacent to the graphics
window. They appear in the order in which they were entered.

The contour is machined longitudinally, transversely or parallel to the contour.
When removing stock along the contour, ShopTurn automatically detects residual
material that has been left. For G code programming, when removing stock, it must first
be decided whether to machine with residual material detection - or not. A suitable tool
will allow you to remove this without having to machine the contour again.
If you programmed a finishing allowance for roughing, the contour is machined again.
