Hexagon Acquire RationalDMIS CMM Software

According to  the Chinese social media web-site ‘WeChat’ Hexagon has announced its acquisition of the software company External-Array, supplier of RationalDMIS coordinate measuring machine (CMM) software.


The google translation of the post reads: “Hexagon is the world’s leading provider of digital solutions that drive productivity and quality improvements in geospatial and industrial enterprise applications. Recently, Hexagon announced the acquisition of the famous American software company External-Array, a supplier of international high-standard measurement software for CMM manufacturers.”

Norbert Hanke, President and CEO of Hexagon Manufacturing Intelligence, said “The acquisition of External-Array has further enriched the Hexagon measurement software solution and provided more software options for basic measurement equipment, especially the RationalDMIS software. The customization function will provide enterprises with services that are closer to the needs of the customer.”

RationalDMIS is the software of choice for most Chinese domestic CMM manufacturers, many of which have grown dramatically in past years, as China has become the largest market for CMMs. RationalDMIS was launched in 2003 and marketed in USA as OpenDMIS by Xspect Solutions (now part of the Wenzel Group).

RationalDMIS offers seamless CAD integration, runs DMIS as its native programming language, and is fully integrated through I++ interface with Renishaw’s PH20 and REVO 5 axis probing technology.

Extensive application modules provide users with enhanced metrology performance including measurement of gears, turbine blades, pipes, and reverse engineering. In addition External Array’s RationalVue is used extensively on Video Measuring Machines (VCMM) in SE Asia.
