Autodesk® Advanced Toolpath Utility for Netfabb® (ATU) is a complete integrated development environment for developing procedures for toolpath creation and export of build data. Once developed, these procedures are used by other software products that provide the initial 3D data and, if necessary, also handle the final machine-specific buildfile generation.
The procedures are developed in JavaScript Edition 5 (with some Edition-6 additions) extended with the custom objects and methods for generating and operating on toolpaths.
Once developed, the code is stored in an Encrypted Build Processor Archive, or EBPA, for use in a host application, typically during buildstyle selection in an additive project. There, the EBPA controls which parameters to expose to the user.
The purpose of encryption is access control: An EBPA can have a password set for each using it in the host application as well as opening it in ATU for code adjustment.
Host applications supporting EBPA buildstyles are currently Autodesk® Netfabb® (Premium and Ultimate) and Autodesk® Fusion 360™.
