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.
