Quality test plan format DFD (ASCII)


The “Q-DAS ASCII Transfer Format” is an internationally established transfer format for measurement data. Its structure is very simple and can be read by many measuring systems, such as coordinate measuring machines and CAQ systems. It consists of two parts: a description file (DFD) and a value file (DFX). Both parts can be combined in a common file (DFQ). You can download the “Q-DAS ASCII Transfer Format Manual” from the Q-DAS GmbH website.

infra CONVERT exports the partial test plans (a partial test plan contains all characteristics belonging to a drawing sheet) either to individual DFD files or combines them to one DFD file.

Note The summary export to a DFD file is available from program version 1.3.8.3.
Info We recommend that you favor the JSONV1 format over the DFD format to connect to your software package. It includes more transferable information and supports all characteristics of infra CONVERT.

You can trigger the export in the start parameter file; see Configuration and Import > Startup Parameter File > Export quality test plans and stamped drawings.

You can find a complete example of a DFD export file here: Appendix > Example quality test plan export file DFD.


File header

Contains data that pertain to the entire file.

Apart from the total number of characteristics, the values are queried when saving in infra CONVERT. The file header is repeated at the beginning of each sub-test plan for a merged file.
