Autodesk® Advanced Toolpath Utility for Netfabb® (ATU) is a complete integrated development environment for developing procedures for toolpath creation and export of build data.
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 may be used in ATU to generate actual build files.
EBPA
The true strength in ATU-developed toolpath algorithms lies in storing them an Encrypted Build Processor Archive, or EBPA, for use in a host application that supports this.
An EBPA can also have a password set each for using it in the host application as well as opening it in ATU for code adjustment. EBPA also control what parameters to expose to an operator, and how the values for those parameters are processed internally.
Host applications supporting EBPA build strategies are currently Autodesk® Netfabb® (Premium and Ultimate) and Autodesk® Fusion®.
