Starting point of turning contour G0-Geo
G0 defines the starting point of a turning contour.
Machining attributes for form elements
All the basic contour elements contain the chamfer/rounding form
element (BR). You can define machining attributes for this form
element and for all the other form elements (recesses, undercuts).
