Export Block attribute (descrition) with dxf file

Hello

I try export a dxf file from a Block , for some reason the Descrition attribut is not exported,

This is a Bug?

Best Regards

That’s not possible even between Autodesk products. The dxf/acad are pretty limited on ‘attribute’ exchange. AutoCAD (.dwg, .dxf) import/export | Rhino 3-D modeling
