Write mesh to DWG without blocks

I want to write a DWG containing a mesh (it is one feature in FME), but it always gets split up into strips with a specific number of vertices like there is a limit (see image). Is there anything I can do about it or is it just a restriction by the DWG format? I'm not very familiar with the DWG datatype, so maybe there is another autocad entity that is better suited?
