基于ManagedMapApi构建多边形实体的研究

Research on Constructing Polygon Entities Based on ManagedMapApi

通过分析AutoDesk的应用程序接口ManagedMapApi,研究了其所创建拓扑面的数据结构,建立了拓朴面与构面图元实体的联系,通过编程实现了多边形实体的创建、存储和空间分析等功能,拓展了AutoCAD Map 3D地理信息数据处理能力。

This paper analyzes the application program interface ManagedMapApi of Autodesk,studies the data structure of the topological face created by Autodesk,establishes the connection between the topological face and the entity,achieves the creation,storage,and spatial analysis of the polygon entity by programming,and expands the GIS data processing ability of AutoCAD Map 3D.
