The fixed facilities comprise fixed facilities such as walls, beams, plates and columns which are manufactured and installed on a construction site, parameter information of the fixed facilities cannot change along with time under the normal condition, and only initial data are required to be acquired and displayed at any moment when urban rail engineering multidimensional display is carried out.

When the BIM model of urban rail engineering is imported into a rendering engine, if all data are imported at one time, high requirements are made on the performance of the rendering engine, and information omission, blocking and even dead halt can occur. Therefore, such an introduction method is not applicable. Therefore, local, batch-wise introduction is required.
According to the technical specialty related to urban rail engineering and the division of space areas during urban rail engineering operation and maintenance, the components of the BIM model of the urban rail engineering are classified, so that the aim of gradually guiding the components into a rendering engine is fulfilled. In the BIM model, data are stored according to the special data package, and according to the characteristic, a special data package can be directly acquired and then is imported into the rendering engine, so that the data acquisition efficiency can be improved, and excessive pressure can not be caused to the rendering engine.

The components are imported in batches and successively, the rendering engine can identify the components imported in advance during the display, and if the components are not required to be displayed, the components can be skipped, and the components are sequentially identified. Thus, the order of importation, if not identical to the order of presentation, can affect the efficiency of recognition. In practical application, the importing sequence is consistent with the display sequence of the BIM model.
