怎样用
extern UFUNEXPORT int UF_CURVE_section_from_planes (
UF_CURVE_section_general_data_p_t general_data, /* <I> Data provided
by the user to to be
used in creating the
section curve feature.
*/
UF_CURVE_section_planes_data_p_t planes_data, /*<I> Sectioning planes
and datum planes.*/
tag_t *section_curves /* <O>
Feature tag, if general_data->associate is 1, or
Group tag of section curves if general_data->associate is 0
and general_data->grouping is 0, or
Group tag of groups of curves if general_data->associate is 0
and general_data->grouping is 1 */
);
就是对第一二个 参数不会设置,怎样调用UF_CURVE_section_general_data_p_t,尤其对
UF_CURVE_section_general_data_s中的tag_t *objects 怎样设置
