The parameterized realization of the bolt flange connection static seal system parts drawing and the automatic generation of the assembly drawing greatly improve the work efficiency, shorten the design cycle and improve the design quality. After the title bar and the technical requirements are automatically generated and the management parameters are designed, the drawings are initialized, the layout of the drawings is performed by human-computer interaction, the type of the drawing, the scale of the drawing and the insertion point, and the format of the title bar are determined. Calculate the drawing area in the frame and output the graphic to the drawing area. Some data information in the title bar is derived from the data in the information model. Other information such as the designer, design date, etc. can be realized by human-machine interaction in the manner of a dialog box, and after the drawing is generated, the information can be extracted and used. Modifications make it easy for designers to modify the design drawings. For technical requirements, the data in the information model is obtained and determined according to national standards. For example, if the material of the flange in the information model is more than 30 mm, 20R and 16MnR should be used in the normalized state. For those that have special requirements, and which are not mentioned in the national standards, they can be additionally recorded in the technical requirements after the drawings are generated, so that the drawings can be managed in a unified manner, using the same as the title bar. The technical requirements can be modified in the same way.
The management of the assembly diagram's dynamic management assembly diagram is the same as the part drawing. It is worth noting that the generation of the assembly drawing schedule, when the algorithm for traversing the BOM table is not appropriate, may cause the system to run slowly or even collapse. It is proved that the hierarchical search method is more feasible to generate the assembly drawing list method. . The parameterized implementation method of the part drawing of the bolt flange connection system and the automatic generation method of the assembly drawing are only applicable to the components with relatively simple structure.
