From DWG with extended data to Featureclass with attributes

Hi. I saw many questions related to the same problem (e.g. "How to convert CAD file xdata into geodatabase?"), but could not really find a solution to this, so I am posting this as a new question.

I have a DWG created in AutoCAD. It has some "solid" entities. I am facing some problems integrating my CAD data with ArcGIS. Here they are:

  1. Although stated in the ESRI official documentation that solid entities should be read as multipatch natively, I fail to import them (the mutlipatch fc generated importing the dwg dataset from ArcCatalog is empty; also look at this thread on "gis.stackexchange"). Is it a recognised problem?
  2. Using the Quick Import tool of the Data Interoperability extension I was able to import the solid entities as multipatch geometries. However I cannot see the related extended data as attributes in the attribute table.

Before asking "How can I translate xdata into feature attributes?" I would like to know from ESRI or someone else facing such problem, "Which is the best procedure in AutoCAD to produce a DWG in order to import it into ArcGIS (ArcMap or Pro) preserving geometries AND attributes"?

I attached the DWG I am using. I am using ArcMap 10.4.1, and ArcGIS Pro 1.4. Many thanks in advance, I would highly appreciate any help!
