We use Pro/E and NX for CAD. We model everything from complex high detailed models for customers wanting to bring their drawings in to the 21th century like a complete CAD assembly model of a nuclear reactor, down to the smallest nut and bolt, all the way to smaller models of interest like a piping system with supports. The in-house knowledge and CAD modeling expertise is the back-bone to all our further engineering work today. As all the models are compatible with our calculation software, this leads to a boost in geometric quality and endless levels of detail for the calculation models that we produce.
