Archicad to Autocad; Layer Problem

[Anonymous]

From the layout folder I save the file as dwg through using '01 For Further Editing'. For ' Save Layout into' option ,I choose ''Model Space' .
I tried everything but when I open the autocad file, there are so many combinations of layers whose I have in archicad. The layers come with prefix. The prefix are named according to the drawing that I put onto the layout. Each drawing are saved as blocks and each layer gets the name of the blocks as prefix. I dont want any prefix, can anyone help me? I tried every way, but I cant figure it out.

I have a similar problem! I imported an Autocad file into Archicad, worked on it with the imported Autocad layers, and now want to export a DWG back to Autocad with the same layer configuration.
Happens that the layers come out duplicated in Autocad with prefixes. It's a mess.

Can anyone help me out with this?

Thanks in advance!
