@RichardHammerl this is a bit evasive, I know you cannot commit here to some specific implementation date, but either this is a planned feature with a TBD date, or this hasnt been justified as something to do and I shouldn't make any plans on ever having the functionality.
I'm asking because this is a _REQUIRED_ functionality, not a nice to have. If something like this doesn't exist and wont within a reasonable timeframe I may have to take my CAD tooling elsewhere. We know Altium has this capability, as does Mentor, Cadence, etc. - and even EAGLE Standalone has this capability, so using Fusion360 as the front end is LESS capable than the prior tool.
So lets cut to the chase. I know that Fusion360 has some code that exists specifically in the interface between the Eagle binary and the Fusion360 binary that is used to transform data extracted from the Eagle files/database - thats how you create the 3D model of a PCB from the component footprints - if that runs as a ULP within the Eagle environment which can be modified to extend the data fields moved between the tools, that would be one solution. Allow the user to select additional attributes within the EAGLE database to be applied to the entities created during the 2D-to-3D conversion.
A better solution would be to use the connector which exists to probe between the environments for arbitrary ULP calls, returning the EAGLE console output from the ULP back to Fusion360. Then I could parse the ULP output string, and decorate the 3D objects using the standard Fusion360 API object model. I'm sure there are a ton of other use cases for something generic like this, and it would help to make both tools more usable for actual commercial/industrial electronics designers.
