Hi,

These are called attribute references (AttributeReference).

They are contained in the AttributeCollection of the block reference.

You can use some function like the following to get the attribute values.

Dictionary<string, string> GetAttributeValues(BlockReference br, Transaction tr) =>
    br.AttributeCollection
        .Cast<ObjectId>()
        .Select(id => (AttributeReference)tr.GetObject(id, OpenMode.ForRead))
        .ToDictionary(att => att.Tag, att => att.TextString)

In the image you posted, the values you circled in red don't appear to be block attributes.

Can you tell more about these values, and where they come from?
