I would like to see a nice graphic UI Schema Editor added into the Model Explorer.
Currently there is a separate InfraWorksDataModelEditor available ([url=http://forums.autodesk.com/t5/infraworks-360-general/create-im-schema-json-with-subsets/td-p/6228076... this post from Andreas Lippold[/url]), and this helps a lot but integrate this in the Model Explorer directly please.
