3D pockets
11.2.5 Profile programming syntax
When programming inside or outside contours of an irregular 3D pocket (with islands) , the following
rules must be complied with:
1. The profile in the main plane indicates the shape of the contour.
Since a 3D contour has an infinite number of different profiles (1 per each depth coordinate),
the following must be programmed:

For the outside contour of the pocket, the one for the surface coordinate (1).

For the inside contours: the one corresponding to the base or bottom (2).
2. The profile in the plane must be closed (same starting and end points) and it must not intersect
itself. Examples:
The following examples cause a geometry error.
3. The depth profile (vertical cross section) must be programmed with any of the axes of the active
plane. If the active plane is the XY and the perpendicular axis is the Z axis, one must program:
G16XZ or G16YZ.
All profiles, plane and depth, must start with the definition of the plane containing it.
