when i open a dxf in edrawings I am missing notes dimensions or some object lines?

I currently have a dxf file that was created in AutoCAD 2014 which is missing objest lines, dimensions and notes when opened in edrawings 2015. I thought was a layer issue so I went into the file and place everything in there appropriate layer. after that i opened in edrawings again and still the same issue? How can I fix this?
