1、Designation:D733107 Designation: D7331 11Standard Practice forSewn Products Marker Data Interchange1This standard is issued under the fixed designation D7331; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revisio
2、n. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes a format for transferring marker data from a CAD marker software system to another or to a CAMsoftware sys
3、tem.1.2 This practice does not support curve interpolation or definitions. All curves are represented by discrete vectors and aredependent 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 prac

5、 of this practice is recommended.1.71.5 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.21.6 This standard does not purport to address a
