Design of Software Architecture for Overhead Line Project Cost Based on 3D Model

3D design is gradually applied in overhead line project, which promotes the reform of overhead line project cost method. Due to a large number of manual participation, the cost compilation pattern of the traditional 2D design has been out of date, and it is not suitable for the development of 3D design. Thus, this paper presents a design idea of the software architecture of the overhead line project cost based on 3D design. On basis of this idea, the specific process of project cost is designed, and the primary platform is constructed, to realize the synchronization of the design and cost data. Finally, the effectiveness of the software architecture is verified by a project case.
