Assembly to DWG issues

Hello People

I'm trying to export one assembly to .DWG, I tried by two different ways (both posted in this forum) and it doesn't work, it show me an error saying that there having some problems and the DWG file may be empty and indeed it is. I don't know if it is the size of the assembly or if I'm doing something wrong.

First Try

You use the join feature to get a single part that is representative of the assembly.

Insert>component>new part.

create a new part on any surface/plane/planar face. exit sketch mode.

While you are still in edit part mode insert>features>join.

Join all the parts and then open the new joined part on its own and save as .dxf

Second Try

I make Assembly in Solidworks

I make drawing of assembly (only view needed for DXF)

I delete all 'sheet format' in the drawing

Save as DXF

Please if someone had have the same error let me know what can I do to solve it
