Because the geometric properties set up in Pro/E three-dimensional modeling process is all linked character, there is the restriction relation of father and son's reference relation, such as, sheet metal component has orthogonal profile, 2 profiles there are threaded hole and square hole respectively, surface-type feature and threaded hole, square hole feature have set membership, arbitrarily cannot adjust the order of this feature in actual design process, and interpolation, deletion feature can cause living again unsuccessfully of linked character.
For the adjustment of realization character order, application coordinate conversion technology, use the reference relation of Pro/ToolkitAPI automatic acquisition current signature, and carry out discrete to reference relation, relative coordinate position is converted to absolute coordinates position, change the father and son's reference relation between feature (profile, threaded hole, square hole), living again after ensureing characteristic sequence change can not be failed, freely adjusting of realization character order.
