Open Data Formats

A changing customer manufacturing and metrology environment has led GOM to identify a number of critical software areas which could lead to significant process efficiencies and integrity improvements.

One problematic area identified is where measurement results, evaluations and reports are often only available in closed data formats. Thus it cannot be guaranteed that such data is available in the long term or useable after a few years.

As a system provider GOM knows of the importance of integration of its technical measurement solutions into the process chain of the users. For this purpose, GOM develops open data formats and thus provides a simple exchange or an optimized archiving of measuring and inspection data.

GOM Inspection Exchange Format / Elements (XML)

The GOM Inspection Exchange Format allows the open data exchange of 3D inspection elements for an open handling of measuring and analysis data.

Among others, the GOM Inspection Exchange Format includes primitives, CMM elements, point clouds, sections and touch probe points (no polygon meshes). This is an open source format and can be implemented without limitations.

With GOM Software Version 8, this format was extended to process additional elements via XML (e.g. meshes, curves, …) and is now called “Elements (XML)” in the software.

GOM 3D (.g3d)

With the GOM 3D format, GOM provides a free data format for 3D datasets. This format is faster in reading and saving data, and is more flexible than the known STL format.

The GOM 3D format is provided since 2002 and today is supported in the established CAD/CAM software packages.
