用 AutoCAD VBA 自动生成仪表位置图

摘要

Making use of AutoCAD VBA’ s secondary development technology and basing on Excel,combining AutoCAD and PDS smoothly to draw instrument plot plan automatically was implemented.This method can mark the instrument location in AutoCAD equipment layout according to the instrument’ s coordinate,and can identify their types and draw their corresponding legends.Both practical application and feedbacks show that this method can increase both accuracy of instrument locating and visuality of equipment layout,and it can de-crease labor strength of designers.%利用AutoCAD VBA的二次开发技术，以Excel为媒介，将AutoCAD与PDS三维建模软件进行无缝链接，实现仪表位置图的自动绘制，该方法能够根据仪表坐标在AutoCAD设备布置图中打点，还可以判别仪表类型并自动绘制相应图例。实际应用和多方反馈证实：该方法在项目项目设计、施工和维护中，提高了仪表点位的准确性和设备布置图的可视性，同时减轻了设计人员的劳动强度。
