PK_ERROR_code_t PK_SESSION_set_swept_spun_surfs
(
--- received arguments ---
PK_LOGICAL_t    whether --- whether swept/spun surfs are to be enabled

--- returned arguments ---
)


This function sets whether topological sweep and spin functions are
allowed to produce swept and spun surfaces.


If whether is PK_LOGICAL_true then the functions:

    PK_BODY_sweep
    PK_BODY_spin
    PK_FACE_sweep
    PK_FACE_spin

may produce surfaces of classes PK_CLASS_swept and PK_CLASS_spun.

If whether is PK_LOGICAL_false then these functions will create
surfaces of class PK_CLASS_bsurf.
