Inventor ETO should have the capability to reverse engineer and configure from an existing iPart / iAssembly factory + incorporate rules from iLogic. There should also be an option to create configurations through a flowchart / flowdiagram rather than through code.
Integrate the Smart Connector functionality found in Factory Design Suite into ETO. The ETO projects that I work on have many configured machines inside a main assembly. To have the ability to configure a machine, drag the machine onto the model window and then have it attach to a chosen piece of geometry would be a great addition to the user experience.
