Hello stefano.rabaioli,
Thank you for contacting Autodesk.
While I do see a lot of value in connecting models between BIM 360 Plan and BIM 360 Field, there is not currently a connection between the two services today. You can connect Revit models between BIM 360 Glue into BIM 360 Field and ultimately into Autodesk Building Ops.
Autodesk is working on building a unified BIM 360 that will be based on a common data environment. Ultimately, this will be a single source of truth for all project data that will be the framework for sharing model data uploaded into BIM 360 Docs with other services like Field and Plan. Announcements in this area were made at Autodesk University (AU) 2016. If you are interesting in knowing more, check out the Autodesk University Product Innovation Keynote from AU 2016. The discussion around BIM 360 starts at Part 4.
Please let me know if that helps or if you have additional questions.
Regards,
Don
