We export DXF AAMA often from Rhino.
It is well explained by @Steve_Howden , the only thing you need to add to that is make sure that once the part is finished, all layers of the part are selected and made into a DXF Block (‘block’ command in Rhino) and that block is on a layer other than any of the instruction layers (1,8, 11 etc) . So put the block onto a layer called ‘fabric’ for example.
