SigmaNEST软件可以直接导入任何主要的二维和三维CAD文件或PDF矢量或光栅文件，以便无痛地创建零件。
自动纠正DXF、DWG、CDL、IGES、DSTV、STEP文件、G代码和NC ESSI代码上的错误。自动修复工具帮助你在导入过程中纠正任何几何图形。可选的过滤模块使用最先进的曲线拟合和实体缩小技术使数字化或扫描的艺术品变得平滑。
下载数据表筛选装配体并使用映射工具，只导入您需要的零件，同时跟踪作业中的所有项目。SigmaNEST能自动识别斜面、铣槽和弯管等特征，以及材料和加工规格。
SigmaNEST 为大多数主要 CAD 品牌提供 CAD 直接导入模块。CAD 直接导入模块为依赖一种 CAD 程序进行大部分零件创建的制造商提供了无缝集成。
对于需要随时导入各种 CAD 文件格式，而无需为每个 CAD 程序单独申请许可证的制造商，CAD Import Plus 模块可以提供帮助。
