Exporting as .emf file does not export my linetypes

I am trying to insert a 2D drawing file into a word report. I want to have a high quality image when I export from word to PDF, I have tried tiff, png and PDF’s.
I have found that .emf file works the best. But rhino does not have options for the export of .emf file. The emf file does not export my linetypes, which is the problem.
Is there a solution to this problem?
