| 摘 要： | 在AutoCAD二次开发中,优化多段线由于可以同时包含直线段与圆弧段,适于表达连续的线,所以在二维曲线绘制方面具有广泛的应用.但因其通过指定多段线顶点的二维OCS坐标数组来生成优化多段线的设计方法的计算量异常庞大,且不易调试,严重影响了二次开发的推广和使用.基于ActiveX技术和面向对象的思想,对将圆弧段封装于顶点之中的动态圆弧顶点数组类clsVerts的设计进行了研究,提高了复杂二维曲线设计与绘图的质量和效率.最后以齿轮坯模锻件图为例对其进行了验证.

| Abstract: | The optimal polyline is suitable for expressing a continuous line due to its covering of line segments and arcs simultaneously in the secondary development of AutoCAD,therefore it is applied widely in two-dimensional curves plotting.However,the calculated amount is abnormal huge for designing the optimal polyline generated from two-dimensional OCS coordinates array through vertex of specified polyline and it is difficulty to debug which may impact the promotion and the use of secondary development.Based on ... |
