Embodiment Construction
[0031] The technical solution of the present invention will be further introduced in detail below.
[0032] combine figure 1 Shown, adopt the method for the present invention to convert the PDMS three-dimensional model into the concrete steps of IFC format file as:
[0033] Step S1, obtaining an element list of the PDMS three-dimensional model. Add the PDMS 3D model to be converted to the PDMS software, obtain the elements selected by the user in the PDMS 3D model, and judge the level of the element in the PDMS 3D model according to the element type, such as WORLD, SITE, ZONE or PIPE, etc. structure, and recurse the elements to the Branch or Equipment level according to their attributes (Members) to form an element list.
[0034] Step S2, obtaining a hierarchical list of the PDMS three-dimensional model. Analyze each item in the element list formed in step S1 one by one, obtain the attribute of a certain element type, and reversely recurse the parent level of its level unti...

The invention belongs to the technical field of three-dimensional model format conversion. In order to solve the problem that a PDMS three-dimensional model cannot be directly imported into BIM software for application at present, the invention discloses a method for converting the PDMS three-dimensional model into an IFC format file. The method comprises the following specific steps: S1, acquiring an element list of a PDMS three-dimensional model; s2, acquiring a hierarchical list of the PDMS three-dimensional model; s3, generating a file header in an IFC format; s4, generating an IFC formatfile auxiliary class; s5, constructing a hierarchical structure of the IFC format file; s6, disassembling a geometric basic body of the PDMS three-dimensional model; s7, transforming the geometric basic body parameter data of the PDMS three-dimensional model; and S8, combining the IFC entities to form an IFC format file. By adopting the method provided by the invention, PDMS three-dimensional models can be converted into IFC format files in batches, and then can be directly imported into BIM software for application.
Description
technical field [0001] The invention belongs to the technical field of three-dimensional model format conversion, and in particular relates to a method and a device for converting a PDMS three-dimensional model into an IFC format file. Background technique [0002] BIM (Building Information Modeling, Building Information Modeling) technology is the direct application of digital technology in the construction industry, because it can effectively support the data exchange between various application systems in the construction industry and the data management of the whole process of the building, through digital information simulation Simulate the real information of buildings, therefore, the application of BIM technology is leading unprecedented changes in the construction industry. [0003] However, since the model results designed by the PDMS (Plant Design Management System) 3D design software commonly used in the field of industrial engineering cannot be directly imported ...
