PK_imprint_extend_t

typedef int PK_imprint_extend_t;

Used in:

PK_BODY_imprint_faces_o_t
PK_BODY_imprint_o_t
PK_FACE_imprint_faces_o_t
PK_FACE_imprint_o_t

This datatype specifies the orientation of the plane used for completing an
imprint. When extending orthogonally on the target, the tool normal is used
as the reference normal, and vice-versa.

It has three values
    PK_imprint_extend_tangent_c     Extend the imprint tangentially.
    PK_imprint_extend_orth_fwd_c    Extend the imprint orthogonally in the
                                    forward direction along the reference
                                    normal.
    PK_imprint_extend_orth_back_c   Extend the imprint orthogonally in the
                                    backward direction along the reference
                                    normal.
