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


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.

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