And when no elbow exists, judging whether a tee joint exists for three times, if the tee joint exists and the tee joint is still contained in 2 meters at two sides of the tee joint, disconnecting the tee joint at the position 0.5 meter outside the two tee joints and increasing flanges. If the valve component is not in three-way, the valve component is judged to be whether or not, if the valve component is in three-way, and a second valve is also arranged in 0.6 m of the two sides of the valve component, the second valve is used as a boundary, and the inner side and the outer side are respectively used as one section.
(2) After the splitting is finished, the splitting breakpoints are identified, numbering programs are sequentially operated on the components at each breakpoint to obtain a plurality of numbered components, then program commands are carried out on the components with the identification numbers, and a top view, a front view, a left view and a three-dimensional view are generated.
