typedef int PK_neutral_error_t;
This datatype contains information about the success of a trim
operation on a neutral sheet.
Success of the operation is indicated by one of these values:
PK_neutral_success_c No problems were detected and a trimmed
neutral sheet has been returned.
PK_neutral_illegal_input_c Either a neutral sheet was not
supplied, or a face was used in
more than one pair.
PK_neutral_numerical_failure_c
An error occurred while trying to
find the trim curves and their
endpoints. The returned neutral sheet
was not trimmed correctly.
PK_neutral_unknown_config_c The disposition of pair faces and side
faces is not recognised by Parasolid.
This is a limitation.
PK_neutral_imprint_failure_c
An error occurred while imprinting
the trim curves onto the neutral sheet.
This often means there is a bug in
finding the trim curves.
