Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as figure 1 As shown, a method for generating a three-dimensional support model in PDMS into a two-dimensional standard three-view method in CAD format includes the following steps:

[0022] (1) In the PDMS software, determine the data that needs to be exported according to the selection of the support that needs to be drawn and the associated pipeline model, and use the DB Listing function of the PDMS software to export the 3D model information as a text document;

[0023] (2) Compile the .Net program to customize the AutoCAD command, read the parts and components such as the section steel, base plate, and standard pipe parts included in the support from the file exported in step (1) according to the number of the pipe support in the three-dimensional model information, and record the location information as AutoCAD three-dimensional coo...

Abstract

The invention relates to a method for generating a three-dimensional bracket model in a PDMS (Plant Design Management System) into two-dimensional plane standard three views, in particular to a method for generating the three-dimensional bracket model in the PDMS into CAD (Computer-Aided Design) format two-dimensional standard three views. The PDMS is used for exporting the DB Listing function of text model information, a calculation command is developed through a .Net development interface provided by AutoCAD software, and three-dimensional model information exported from the PDMS is read according to a bracket number input by a user, the two-dimensional standard three views and the bill of materials of the bracket are automatically generated, and a one-key drawing output function from the PDMS three-dimensional model is realized. By use of the method, inherent defects that an operation for the drawing output software of the PDMS to output a DXF (Drawing Exchange Format) drawing is complex, the deep requirement of an engineering drawing can not be met and revision regulation is difficult can be avoided by aiming at the characteristics of a pipeline bracket, the customization and the generation of the standard two-dimensional drawing of the pipeline bracket is realized, the drawing output time of design personnel is shortened to a maximum degree, and the design efficiency of pipeline bracket design personnel can be effectively improved.

Description

technical field [0001] The invention relates to a technology for generating standard three-view and finite element analysis models of a three-dimensional software pipeline support, in particular to a method for generating a two-dimensional standard three-view in CAD format from a three-dimensional support model in PDMS. Background technique [0002] The number of supports for nuclear power engineering pipelines is huge. In the case of tight design time nodes and tight personnel, in order to ensure the smooth completion of the new design, designers need to improve design efficiency to meet the requirements of the nuclear power project construction period. With the continuous advancement of technology, the use of large-scale 3D design software (such as PDMS) for engineering design has become mainstream. However, in order to meet the requirements of versatility, the PDMS software has its own bracket drawing tool to operate cumbersomely, the output drawings do not meet the dept...
