Synopsis
PDX_MSGT igeo_Get142Sense(long option, MDA_PTR db_ptr, PDX_BOOL outer_trim, int *sense)
Purpose
Get the sense of an IGES 142 entity
Description
Given a closed IGES 142 entity and wether or not the IGES 142 is an outer or innter trimming boundary determine the sense of the boundary. The IGES 142 entity may be an invalid entity that references either the model space curve or the parameter space curve and may reference the plane entity with the model space curve as the trim curve and the sense will be determined.
Input
option
Option (Not used)
db_ptr

outer_trim
PDX_TRUE
The IGES 142 is an outer boundary
PDX_FALSE
The IGES 142 is not an outer boundary
Output
sense
The sense of the trim boundary 1 - The sense of the trim boundary does not need to be reversed 2 - The sense of the boundary needs to be reversed
Return
IGEO_NOERR
