@Nord_lenningen @aothms@yorikvanhavre@theoryshaw @chopinregis The process of import/merge in the server is about data management. 'Roundtrip' is a workflow concept/principle. Those are different things. We have not seen use-cases that nééd round trip between multiple software tools. Happy to receive more info on your data flow goals.
@aothms@yorikvanhavre @Nord_lenningen @theoryshaw @chopinregis 2/2: Submitting an IFC dataset (file) as an update of a previous revision is also an option. The merging algorithm to integrate the update into the previous revision, is handled by a plugin (that can be configured to your wishes and preferences).
@aothms@yorikvanhavre @Nord_lenningen @theoryshaw @chopinregis response 1/2: There are 'low level service calls' in @BIMserver to edit the data (changes will be stored as new revision). There are many network structures in IFC that you have to take into account though.
