Achieving the holy grail of seamless CAD data import into analysis software

One of the difficulties in electromagnetic modelling has been the lack of standard CAD data to enable direct import of data into analysis software. Many solid modelling standards have been proposed over the years, but due to the many separate interests involved and differing geometrical requirements, a definitive standard has been elusive. Recently the ACIS based SAT format has gained favour and can be produced by many proprietary CAD drawing packages. This paper exemplifies a modern electromagnetic analysis tool that is able to directly import SAT format data.
