摘要
为满足企业对锅炉管道施工图的快速生成需求,基于给定的管道信息,结合投影规律,提出并实现了基于三维空间定位点的管道自动施工图生成算法,该算法能够自动确定主视图的方向,自动对图形进行打断,自动完成二面角视图以及局部视图的判断和绘制。通过在企业的实际应用中证明了算法的可靠和高效。
To meet the needs of rapid generation of engineering drawing of boiler pipelines for industrial plant,based on the given information of pipelines,taking the factor of projection regular pattern into consideration,an algorithm about automatic generation of working drawing of pipelines based on anchor points in 3D space is proposed and implemented.The algorithm can determine the direction of Principal View,break the pipe automatically and complete the judgment and generation of dihedral angle view and partial view automatically.The reliability and effectiveness of this algorithm is verified in a practical application on enterprise production.
