A pipeline three-dimensional modeling method and a pipeline design method

Abstract

The invention discloses a pipeline three-dimensional modeling method and a pipeline design method, wherein, the pipeline three-dimensional modeling method comprises the following steps: obtaining a pipeline geophysical prospecting table; according to the data in the pipeline geophysical prospecting table, the end point elevation of all pipe segments is calculated, and the pipe center elevation value is put into a single column in the same row of the corresponding pipe segments in the pipeline geophysical prospecting table; generating AutoCAD command string in pipeline geophysical exploration table; using AutoCAD software to run AutoCAD command strings, and generating the three-dimensional models of all pipelines in different layers. It greatly improves the efficiency of pipeline design, which is convenient for designers to carry out pipeline comprehensive design, and also visually facilitates the proofreading and auditing work.

Description

technical field [0001] The invention belongs to the field of pipeline modeling, in particular to a pipeline three-dimensional modeling method and pipeline design method. Background technique [0002] When carrying out the comprehensive design of municipal pipelines, the pipeline comprehensive designers usually get the current AutoCAD geophysical prospecting plan made by the surveying and mapping department provided by Party A, and then add new design pipelines or transform the original pipelines in the figure, but they are all 2D drawings . Although there are lines representing pipes on the diagram, since the lines do not have the attribute of pipe diameter, it is impossible to visually check whether there is collision between pipes and whether the clear distance of pipes meets the specification requirements. For the horizontal clear distance between the pipes, it can only be obtained by measuring the plane distance between the two lines in the figure and subtracting half o...

Problems solved by technology

Although the outdoor current pipeline can be modeled in Autodesk Civil3d software, the AutoCAD geophysical plan is used as the reference base map, and the "create pressure pipe network from object" command is used to pick up lines to generate pipelines, and build them manually one by one. However, for the huge number of pipelines in a pipeline project, the design is still very laborious

[0004] There are many 3D pipeline modeling development languages ​​on the market, such as C++, Lisp, VB and other high-level languages ​​for secondary development, but these will be very difficult for ordinary designers who have not learned software programming, and self-development will require investment more time and energy
