Significance and UseThis 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.Scope1.1 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.
