Some of the primitives contain a contour group. The Layout of such a group is the following:

START_OF_3D_CONTOUR

indicating the start of a contour

NO_OF_SEG

START_X

START_Y

START_Z

AX

AY

AZ

implicit zero amplitude vector

.....

any number of segments

.....

END_OF_3D_CONTOUR

indicating the end of a contour

A contour must be planar. If not, serious tolerance problems may occur when the data are used in the system, for example, for interference check.

There is no limit for the number of segments in a contour, but for performance reasons, the number should be as low as possible.
