This probably belongs in a Design Review or DWF Ideastation but since I don't see one I'm posting here.
Export DWF from Inventor needs some work for embedded OLE objects. I have an Excel file pasted into a drawing sheet that looks fairly awful (blurry text) when viewing the page in Inventor but looks sharp when printed to hardcopy or using the DWF Writer for 2D. Export To DWF also creates blurry text and this seems to be what Update View in Vault uses because that creates blurry text as well.
I tried attaching DWF files to this post but the attachment section kept stating 'The contents of the attachment doesn't match its file type' and wouldn't let me post them.
