specific Embodiment

[0039] See Figure 2 to Figure 7 ,

[0040] 1. Establish a database: firstly, determine which parameters are required by the component, and divide the parameters into external input parameters, internal calculation parameters and output parameters according to the requirements. For example, the saddle type pipe joint, its external input parameters are the outer diameter, wall thickness, height, etc. of the pipe joint; the internal calculation parameters are the main pipe radius, main pipe opening value, etc.; the output parameters are the pipe joint inner diameter, welding height, welding width, tc Wait. Give each type of pipe fittings a letter code, and the code should be clear from the name. To facilitate the selection of designers.

[0041] 2. Establish a symbol library: The detailed drawings on general pipeline drawings are mainly divided into pipe joint opening drawings, pipe joint welding drawings, pipe fitting butt joint drawings, and groove detailed drawings. Make ...

Abstract

The invention provides a computer-assisted plotting method for waste heat boiler pipes. An arranged three-dimensional model can be directly transformed into a two-dimensional drawing for workshop production, and production efficiency can be improved. The computer-assisted plotting method is characterized in that the three-dimensional model is seamlessly integrated into a PDMS (plant design management system) platform by the aid of a program developed by a PML (printer management language), all information in the three-dimensional model is rapidly read, corresponding two-dimensional drawings pointed to by existing three-dimensional model information in a database and a symbol base are called, and the two-dimensional drawing directly used for workshop production is generated. The method specifically includes the steps: building a database of existing pipe fittings; building the part drawing symbol base of holes, welds, grooves, detailed drawings and nozzles of the existing pipe fittings; arranging pipes in a design platform and inputting relevant information as required; analyzing the obtained three-dimensional model information and automatically generating planar drawings.

Description

technical field [0001] The invention relates to the technical field of computer-aided drawing, in particular to a method for computer-aided drawing of waste heat boiler pipes. Background technique [0002] Domestic boiler design has always been based on two-dimensional design. Before the popularization of computers, it mainly relied on T-square and drawing wrench working drawings. After the birth of autocad, the design platform has basically turned to computer graphics. Designers still cannot avoid falling into the pattern of repeated drawing and mechanical labor, and because the drawings cannot be effectively checked automatically, the error rate of the drawings of many companies remains high, which has a great impact on the on-site construction, resulting in A lot of money and time loss. In view of this situation, the domestic design field began to introduce 3D design software around 2000, which made the design more intuitive, and at the same time, the collision chec...
