Indication of which end of the string should be trimmed or extended to the bounding object, this should be set to one of the following values: UF_CURVE_TRIM_EXTEND_START UF_CURVE_TRIM_EXTEND_END
Vector defining viewing direction in which to measure minimum distance. If vector is defined with a datum axis, the feature will be associated to the datum axis. If vector is defined using plane of curves option, curves do not need to be supplied in vector structure, the bounding object strings and string being trimmed will determine plane. If (void )0 then minimum distance will be measured 3 dimensionally.
