基于 ObjectArx 技术的横断面自适应提取

为降低水利、公路等线路工程中横断面提取的复杂度，本文针对横断面提取的特点和专业要求，结合不同行业应用需求对横断面自适应提取进行了分析和研究，给出了涉及的关键算法和数学模型。在AutoCAD环境下基于ObjectARX技术实现了多种数据源的横断面自适应提取。项目生产实践表明，该方法显著地降低了劳动强度，提高了生产效率。

Adaptive Extraction of Cross Section Based on ObjectARX

For reducing the complexity of cross section extraction in the field of route engineering like hydraulic engineering and high-way engineering, we make a detailed research on adaptive extraction of cross section which combined with application requirements in diversified fields by their features and professional standards, and describe the key algorithms and mathematical model.What’ s more, by using ObjectARX in AutoCAD we have also implemented the adaptive cross section extraction with different relational data sources. It is proved to be true by our practice projects which can decrease the workload obviously and upgrade the efficiency.
