Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering design, and particularly relates to a method and system for generating a three-dimensional visual entity based on a two-dimensional path and a medium. BACKGROUND

[0002] With the rapid development of the digitalization process of building engineering, the development of building engineering design is also more and more sequential, and the requirements for building engineering design are also higher and higher, and the level of design needs to be gradually strengthened. In the electrical field of building engineering, in order to meet the requirements of full digitalization, the intelligent application of the plane design, parameter selection, and load calculation of the conductor also requires more and more accuracy, efficiency, and convenience.

[0003] In the plane design of the traditional building engineering electrical field, the plane design of the conductor is completed by adopting the way of path planning and channel construction; based on the conductor laying in the plane design, a three-dimensional electrical conduit of building electricity can be automatically generated, which represents the actual channel model and belongs to the part of channel construction; and the actual conductor model generally needs to be virtually represented based on the electrical conduit and the physical channel such as the bridge as the carrier, represented as a logical connection, and cannot be represented as an independent three-dimensional model. Similarly, the actual length statistics of the conductor are indirectly calculated and counted based on the actual path of the physical channel.

[0004] At present, in the field of building engineering electricity, the conductor based on the plane design cannot be directly automatically generated into a three-dimensional visual conductor, but only the three-dimensional electrical conduit can be generated based on the plane design of the conductor, and the physical channel construction of the conductor is completed based on the electrical conduit and the pre-designed bridge, and the three-dimensional logical conductor is indirectly generated. Further, in the traditional plane design, when multiple conductors intersect, or the conductor is not connected with the equipment but visually intersects, the same conductor will be broken into multiple conductors. However, the multiple conductor objects still represent the same conductor, and when the three-dimensional electrical conduit is generated, multiple electrical conduits will be generated, which causes inconsistency in the entity and plane design expression. Moreover, the elevation setting of the conductor needs to be completed at the same time as the plane design, which increases the design dimension and seriously affects the design efficiency. SUMMARY

[0005] The technical problem to be solved by the present application is that the conductor in the traditional building engineering electrical design plan cannot directly generate a three-dimensional entity, the logic expressed by the plan design is inconsistent with the generated entity, and considering the influence of three-dimensional entities on the design efficiency when designing the plan; the present application aims to provide a method, system and medium for generating three-dimensional visual entities based on two-dimensional paths, establish a dictionary representing the logical connection and entity path of the conductor in the plan design, and consider the consistency of the plan and three-dimensional entities in the case of different expression and entity mapping of the plan design; and based on the floor dictionary, equipment installation dictionary, bridge dictionary and conductor dictionary, automatically correct the three-dimensional entity of the conductor, improve the design efficiency, reduce the complexity of the designer for forward design, and also lay the entity foundation for the conductor calculation.

[0054]

[0055] determining whether the target device intersects with the conductor in the plan design, the target device including an electrical distribution box in the floor and an electrical end device in the floor; if so, saving first installation information of the target device as a device installation dictionary, the first installation information including installation mode, installation height, and installation position; the device installation dictionary is shown in Table 2;

[0062] if there is no intersection point, saving the current line segment to the conductor logical connection dictionary;

[0063] if there are two intersection points, dividing the current line segment into a first sub-line segment and a second sub-line segment based on the target device and saving them to the conductor logical connection dictionary, wherein the first sub-line segment is formed by a line segment with a first new starting point of the current line segment offset by a distance n or 1 / 3 of the current line segment from the original starting point, the first new starting point being the closest intersection point to the original starting point of the current line segment; the second sub-line segment is formed by a line segment with a second new starting point of the current line segment offset by a distance n or 1 / 3 of the current line segment from the original ending point, the second new starting point being the closest intersection point to the original ending point of the current line segment;

[0066] The method for constructing the conductor path dictionary comprises: connecting the key point set of the conductor in the plan design in sequence to form a polyline, and saving the polyline to the conductor path dictionary to represent the conductor entity path.

[0067] As shown in Figure 2 The conductor dictionary comprises a selection mapping link (the selection mapping link_linesBeSel corresponds to the conductor path Count=1, and the selection mapping link_linesBeUnSel corresponds to the conductor path Count=2), which is associated with the conductor path dictionary. The selection mapping link can perform the plan design graphic transformation on the target conductor selection and unselection. When the target conductor is selected, the plan graphic is constructed in the manner of the dictionary representing the conductor entity path by mapping, as shown in (b) of Figure 3 When the target conductor is unselected, the plan graphic is constructed in the manner of the dictionary representing the conductor logical connection by mapping, as shown in (a) of Figure 3 The three-dimensional entity is always generated based on the dictionary representing the conductor entity path, so that the inconsistency between the conductor three-dimensional entity and the plan design expression can be solved by adopting the manner.

[0072] A vertical line segment L1 and a vertical line segment L2 are generated at the start position of the first segment and the end position of the last segment of the horizontal multi-segment line respectively, and whether the target conductor is generated from the top plate is determined according to the conductor information dictionary; if yes, the vertical line segment L1 and the vertical line segment L2 are directed downward, otherwise, the vertical line segment L1 and the vertical line segment L2 are directed upward.
