CAD中图元线型分割算法的研究和实现

Research and Realization of Line Type Construction for CAD

为了实现CAD绘图中线型的所见即所得显示,文章通过分析国家标准对线型绘制的要求以及程序设计中线型分割算法的不足,提出并实现了一种基于代数求解的线型分割算法,并针对可见区域的快速显示进行了分析,给出了具体的算法流程。该算法应用到实际的CAD系统中,验证了算法的可靠和有效性。

To realize the effect of display for ＂what you see is what you get＂ of the line drawing in CAD, the relative national standards are studied and the defect of linear cutting algorithm in programming is discussed. Based on algebraic methods, a new linear cutting algorithm is proposed and implemented. Analysis of its fast display of printer area is also conducted and a specific algorithm flow is provided. The effectiveness of this algorithm is verified in a real CAD system.
