This structure provides options for a linear extrusion of a body.


Specific Errors:
    PK_ERROR_unsuitable_entity     'extruded_body' is provided but is either
                                   not a solid body when the 'profile' is a
                                   sheet body, or is not a sheet body when the
                                   'profile' is a wire body (MILD)

    PK_ERROR_bad_angle             'pline_angle' is provided but isn't within
                                   the interval ( 0.0, pi ) (MILD)

    PK_ERROR_inconsistent_geom     'keep_as_facet' is
                                   PK_BODY_keep_as_facet_yes_c, the profile
                                   contains only facet geometry, and either
                                   (a) the bound method is not
                                   PK_bound_surf_c, or (b) the bound entity
                                   is a classic surface of a class other than
                                   PK_CLASS_plane (MILD)

Used in:

PK_BODY_extrude

Its fields are:

'start_bound'         How the extruded body is to be bound at the start bound.
                      See documentation for PK_bound_def_t.

'end_bound'           How the extruded body is to be bound at the end bound.
                      See documentation for PK_bound_def_t.

Note: 'start_bound' and 'end_bound' must occur in that order along
the given 'path' vector.


'extruded_body'       Perform the bounding on this body instead of the swept
                      profile.

'allow_disjoint'      Whether the resulting extruded body can have disjoint
                      components.

'consistent_params'   Whether or not to always make the parameterisation
                      consistent with the sweep direction.

'have_pline_angle'    Whether 'pline_angle' is supplied.

'pline_angle'         For profiles with facet geometry, if the angle (in
                      radians) between polyline segments, when viewed down
                      the direction of extrusion, is greater than or equal to
                      'pline_angle' then an additional edge will be introduced
                      in the resulting body, extruded from that position. On
                      wire profiles this applies to any polyline, and on sheet
                      profiles this applies only to polylines on laminar
                      edges.
                      If 'have_pline_angle' is set to PK_LOGICAL_false, the
                      angle criterion won't be used to split edges.
                      See also #here#DOCXXXX# for more information.
                      Note: this option has no effect if an 'extruded_body' is
                      supplied.

'keep_as_facet'       Whether the resultant extrude body is to contain only
                      facet geometry.
                      Note: this option has no effect if the extrude profile
                      contains any classic geometry.
