The key of the BIM technology application lies in the information transmission and sharing, but the conversion efficiency of the BIM model of the same project among different BIM platforms is low and the workload is large at present. The building block is an important component of the BIM model, and the complete and efficient conversion of information of the building block is crucial to engineering collaboration across the BIM platform.

Some existing three-dimensional modeling software has rich and complete family files, but is complex to operate, very strict in family parameters and constraint conditions, not in line with the operation habits of users, and high in the difficulty of manual operation of the users. In addition, the types of components on the current market are various, and a unified family library does not exist, so that the quality of models built by users is uneven, a plurality of models cannot support subsequent use, and a large amount of manpower and material resources are wasted. In order to effectively utilize components in the existing family files, the extraction work needs to be carried out on the family files, so that the display and editing work of basic primitives (unit components in the model) can be provided for the BIM model, the BIM model can be accurately and efficiently established on different BIM platforms, the design efficiency is greatly improved, and the digital and intelligent transformation and upgrading of the building industry are facilitated.

Fig. 1 is a flowchart illustrating a BIM platform based component generation method according to an exemplary embodiment, as shown in fig. 1, the method including the following steps.

Step 101, acquiring basic data in a family file corresponding to a target component, and preprocessing the basic data to extract target information of the target component, wherein the basic data comprises geometric data, constraint information, family parameter information and family type information;

it is an object of embodiments of the present application to convert high quality BIM components into a format that can be used on a target platform and visualize the BIM components on the target platform. The information corresponding to the BIM component is stored in the family file, and the basic data in the family file corresponding to the target component is extracted firstly. The basic data is further extracted to keep the most basic information required by generating the target component, and the extracted information is the target information.

in the embodiment of the application, the extracted target information corresponds to different target components, and the corresponding relation between the target information and the target components is stored through the database, so that the target platform can conveniently obtain the corresponding relation between the target components and the target information.

Step 103, generating a three-dimensional visualization component corresponding to the target component on a target platform according to the content of the storage database.

In a possible embodiment, the family file corresponding to the target component is a family file in a three-dimensional modeling software REVIT, the REVIT has rich and complete family files, but the operation is complex, the family parameters and the constraint conditions are very strict, the user has great difficulty in manual operation, the target information is extracted from basic data in the REVIT, and a storage table is generated by the relationship between the target information and the target component. The three-dimensional schematic diagram of the target construction can be generated on other BIM platforms according to the storage table by using the elements of the BIM platforms, the components in the REVIT are converted into the formats which can be conveniently used on different BIM platforms, the richness of the components on the BIM platforms is improved, and the modeling efficiency of the BIM platforms is improved.

In the embodiment of the present application, the type of volume data in the family is a type of a component, and includes four major categories: lofting, stretching, fusing, and rotating. In lofting, a two-dimensional object is used as a section along a path to form a complex three-dimensional object, and different shapes can be given at different segments on the same path. We can use lofting to enable the construction of many complex models. The stretching body is a three-dimensional object formed by stretching a two-dimensional body object along a certain direction, and the stretching direction can not enable the two-dimensional bodies to be in the same plane. A fusion is a three-dimensional object obtained by fusing a plurality of three-dimensional bodies together. A rotating body is a three-dimensional object that is generated by rotating a two-dimensional body object by a certain angle along a certain rotation axis.
