I hate Windows, so I will get much love here. I love Visio however, and most of the stencils I need for network engineering are in .vss format. Is there a simplistic way of converting a .vss visio stencil into a .svg or something that yed or dia or whatever drawing diagram, can understand?
LibreOffice Draw supports the Visio file formats for drawings and stencils: http://libregraphicsworld.org/blog/entry/libreoffice-gets-visio-2013-support
Other web-based diagramming tools such as Creately supports Visio file formats too: http://creately.com/blog/announcements/introducing-visio-import/
Note that there are two file formats: the traditional VSD and the XML-based VSDX (since Visio 2013). Yoy may find information on the formats and some opensource libraries you can use at:
