typedef int PK_FACE_trim_confine_t;
This data type is used to select how a trimmed surface is to be confined.
It has four values:
PK_FACE_trim_confine_no_c Trim loops will not be confined to
a single period on periodic faces. The
trimmed surface returned may have more
than one outer boundary(e.g. the ends of
a cylinder). The SP-curves in a loop may
have gaps between them in parameter space
where there are degeneracies.
PK_FACE_trim_confine_yes_c Trim loops will be confined to a single
period on periodic faces. The trimmed
surface returned may have more than one
outer boundary (e.g. the ends of a
cylinder). The SP-curves in a loop may
have gaps between them in parameter space
where there are degeneracies.
PK_FACE_trim_confine_closed_c Trim loops will be confined to a single
period on periodic faces. All the trim
loops will be closed and without gaps in
parameter space. Each trimmed surface will
have no more than one outer peripheral
loop. The outer peripheral loop may be
omitted if it does not trim off any of the
surface.
PK_FACE_trim_confine_periph_c Trim loops will be confined to a single
period on periodic faces. All the trim
loops will be closed and without gaps in
parameter space. Each trimmed surface will
have exactly one outer peripheral loop.
