Exporting Block Reference Attributes in Rhino/Grasshopper

Hi everyone,

I have a block reference in autocad containing attributes that I would like Grasshopper to read.block%20reference%20attributes_img block%20reference

When importing the .dwg or .dxf in rhino, the block seems to explode so the insertion point has no link to the other attributes.

How not to lose those attributes attached to a block insertion point ?
