摘　　要：针对目前对切片方案的评价只能通过实际成品来事后检验,提出了一种3D矢量模型切片方案的预测评价方法。根据封闭轮廓环点集和工程图文件两种数据类型对3D模型进行重建,并计算扫描路径总长。通过2D逐点连线及3D逐层拉伸技术完全模拟实际的叠层制作过程,得到跟切片方案相对应的具有阶梯效应的可视化模型。实验表明,该方法可对切片数据进行快速3D重建及路长计算,其结果可用于切片方案的预测评价,有效降低了开发成本。To against the demerits of verifying the slicing proposal by post-estimating to finished products afterwards,this paper presented an evaluation method for the slicing proposal.It developed reconstruction algorithm of 3D vector model and path length calculation method based on two kinds of data type which were the closed contour point sets and the 2D engineering drawings.It simulated the laminated object manufacturing processes completely through plotting lines or arcs point by point and the 3D extruding layer by layer,and output the visualization model with staircase effects corresponding the different slicing proposals.Case study shows that slicing data can be reconstructed to 3D model rapidly,and the path length calculation can be used to predict total processing time.The development cost can be efficiently reduced by the valuation method
