I have a macro that converts (save as) sheetmetal part into .DXF  This works on all users PC except one.  The normal result is ex.  chain.dxf  on this one users pc it saves it as chain.sldprt.dxf

I have looked in Solidworks settings/Export Options and can't find the answer as to why it is putting the filetype in the file name.  This is only on 1 pc so I know it has to be a setting somewhere that I have missed.  It will likely be the easiest and most obvious one too.  Any help??
