(5) the straight tube pipeline height of piping lane center line section is calculatedI.e. according to above-mentioned coordinate computer tube
The absolute growth of corridor center line segment in the vertical direction.
(6) pre-set threedimensional model is matched according to straight tube pipeline height H, caliber DN and length of straight pipe L and generates three
Tie up straight tube.It needs to illustrate, pre-set threedimensional model can flexibly be chosen according to user's use demands, example
Such as, the master pattern etc. being directly generated in advance in CAD according to two dimensional pipeline data.In implementation process, by what is calculated
Straight tube pipeline height H, caliber DN and length of straight pipe L are put into matching threedimensional model and generate three-dimensional straight tube.It additionally needs
Under explanation, matching selection process, parameter, number of parameters of the input and output for the master pattern being generated in advance etc. be not true
It is fixed, the threedimensional model to match with above-mentioned parameter, number of parameters is first searched when choosing matched threedimensional model.
Step S102 calculates the difference in height between adjacent three-dimensional straight tube, also, generates three-dimensional vertical tube according to difference in height, specifically
Including：
(1) since three-dimensional vertical tube is provided in for what is played a supportive role between three-dimensional straight tube, and therefore, it is necessary at least two
A horizontally disposed piping lane center line segment calculates and generates three-dimensional vertical tube, remembers previous piping lane center line segment in implementation process
Make F, the latter piping lane center line segment being attached thereto is denoted as B.
(2) the terminal frame for obtaining previous piping lane center line segment rises FEh, F is risen by the vector parameters terminal frameEh's
It obtains to weigh the altitudes of previous piping lane center line segment.

Under, swing situation and the latter piping lane center line segment in the horizontal direction when previous piping lane center line segment is in the horizontal direction
The situation that swings it is inconsistent when, will produce corresponding difference between three-dimensional straight tube and three-dimensional vertical tube, need different cambers
Elbow is connected.
(4) therefore, the rotation angle of elbow is calculated according to the yaw angle between the line segment of above-mentioned two piping lane center
(5) also, in order to consider elbow itself swinging in the horizontal direction, when implementation, calculates the yaw angle of elbow
(6) after, according to rotation angle WΦAnd yaw angleGenerate three-dimensional elbow.It needs to illustrate, above-mentioned three-dimensional
The aperture width of elbow is slightly larger than above-mentioned caliber DN, when specific implementation the numerical value of the aperture width of three-dimensional elbow can according to circumstances into
Row flexibly setting.
Above-mentioned steps S104 at three-dimensional piping lane model, specifically includes three-dimensional straight tube, three-dimensional vertical tube and three-dimensional bend-head combination：
(1) during forming three-dimensional piping lane model, the starting point coordinate of model is first determined, it is generally the case that model
