Visio Stencils for SharePoint 2007 sites and servers
I've put up together a Visio 2007 stencil that I use for creating SharePoint Site Structures and architecture.
Update : You can find an updated post with more pictures and updated stencils at https://blogs.msdn.com/maximeb/archive/2007/10/27/updated-visio-stencils-for-sharepoint-2007-site-structures-documentation-version-0-2.aspx .
This is a complement to the architecture/server one available on this blog address : https://blogs.tamtam.nl/mart/MOSSArchitectureDiagramsVisioServerStencils.aspx. This stencil is also interesting for designing Page Layouts : https://www.nickfinck.com/stencils.html.
For SharePoint 2003, you can also find one here : https://blogs.tamtam.nl/Ferry/SearchView.aspx?q=stencil.
