The ease of use of SUM3D is one of its main features. Indeed, to learn how to use software it is necessary one day training only. The setting to enter commands is based on the machining tree and allows a quick and intuitive definition of all the machining parameters. To ensure the reliability of the generated paths, SUM3D uses calculation that always take into account the anti-collision control both on tools and their associated components. There are also features for the analysis of the calculated routes.
