摘要

AutoCAD2014软件中有点选、窗选和框选等多种选取设计对象的方式。已有这些选取方式在选择沿圆弧排列的设计对象时效率不高,为此提出了一种新的扇形框选方法。介绍了扇形框构建过程,分析了如何创建扇形框中的选择集,基于AutoCAD2014软件、采用ObjectARX作为二次开发工具开发了扇形框选插件。设计人员只需要点选一个圆弧即可确定圆弧对应的圆心位置、外加确定的两个对角点位置,利用开发的插件就能快速绘制一个扇形框并能选中扇形框内部的几何实体。以轮胎模具文字符号设计为例验证了这种扇形框选方法的高效性。
        AutoCAD2014 software can provide several select design objects methods such as a click selection,a window selection and a box selection. Because these selection methods are not efficient to choose the design objects which arranged along an arc,so a new fan box selection method is proposed. The principle of how to construct a fan box is explained and the process of how to collect selected objects is analyzed. Based on AutoCAD2014 software,a fan box selection plug-in is developed using ObjectARX as an application developing tool. When an arc is selected the center of it can be determined.When two diagonal points also have been confirmed,using this developed plug-in,a fan box can be quickly drawn and the suitable geometric entity inside it can be effectively selected. Using a tire mold character design as an example the efficiency and the validity of this new fan box selection method has been verified.
