The house Entity establishes association with the primitive element through a first association table, for example, the Elem _ GUID attribute of the primitive is associated with the Elem _ GUID field of the primitive association table, and the Entity _ GUID attribute is associated with the Entity _ GUID field of the primitive association table.
When the house entity generates according to the primitive data, the information of the global unique identification field for determining the existence of the house entity can be automatically generated.

For example, in a specific application, for example, the display characteristics of the primitive elements associated with the target house entity are modified to distinguish the display manner (point, line, plane, size, thickness, brightness, color, texture, and dynamic) of the target house entity from those of other house entities.
As another example, in a particular application, primitive information masking, disguising or emphasis of the relevant house entity is implemented.
It should be noted that steps 104 to 105 of the above embodiments are optional. For example, in the authentication reading condition, the authentication display or the prohibition display may be further implemented.

For example, the concrete body 1, the concrete body 2 and the concrete body 3 together constitute a house entity.
The main house and the subsidiary houses connected with the main house jointly construct the same house entity, and for example, house subsidiary facilities such as outdoor stairs, column galleries, drifting buildings, eaves galleries, door tops, gallery houses and the like participate in constructing the house entity. And the house entity inherits the attribute of the maximum area fixed field of the house primitive. The same house entity generally has the same characteristics of structure, material or appearance texture and the like.

The different primitive elements can be distinguished through the primitive control codes, so that the distinguishing display can be realized, including the distinguishing display of different primitive data in the target house entity and other house entities or the target house entity.
