1.1本规程描述了将标记数据从CAD标记软件系统传输到另一个或CAM软件系统的格式。 1.2本规程不支持曲线插值或定义。所有曲线均由离散向量表示，并取决于CAD软件的分辨率。 1.3本规程旨在限制在不同CAD系统上处理相同数据时的差异。 1.4本规程不代表图案块之间或图案尺寸之间的尺寸关系，也不代表2D或3D缝制产品图案块几何形状之间的对应关系。 1.5本标准定义的标记数据交换文件的文件格式符合XML格式。 1.5.1描述标记数据交换标准XML结构的XML模式在ASTM附件中提供。 1.6 本标准并非旨在解决与其使用相关的所有安全问题（如有）。 本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 该实践旨在允许嵌套软件或CAM系统之间的标记数据交换。 由CAD系统导出的工件描述专用于CAM系统。

1.1 This practice describes a format for transferring marker data from a CAD marker software system to another or to a CAM software system. 1.2 This practice does not support curve interpolation or definitions. All curves are represented by discrete vectors and are dependent on the resolution of the CAD software. 1.3 This practice is concerned in limiting differences when processing the same data on different CAD systems. 1.4 This practice is not intended to represent the dimension relationships between pattern pieces or between pattern sizes, or the correspondence between 2D or 3D sewn product pattern piece geometries. 1.5 The file format for the marker data exchange file defined by this standard complies with the XML format. 1.5.1 The XML schema describing marker data exchange standard XML structure is presented in an ASTM adjunct. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This practice is intended to allow marker data exchange between nesting software or CAM systems. The pieces description, exported by a CAD system, is dedicated to CAM systems.
