Since I am a Mac user, I use Omnigraffle Pro to create technical diagrams for documentation purposes. Many of my collegues use the PC counterpart, Visio. I have found a really nice site for Vendor specific stencils. It is called Visio Cafe. Visio Cafe has up-to-date stencils for IBM and HP equipment, to name a few. Visio Cafe does not have Cisco shapes, but do not fear. Here is the link to Cisco’s Visio Stencils page.Visio users can import Visio Cafe’s stencils directly. Omnigraffle users cannot. Omnigraffle users have two choices, either search the Omnigraffle’s Extras page or use the Stencils->New Stencil function to create your own. I use my organization’s Citrix client to launch Visio. I then create a new stencil in Omnigraffle, and then copy and paste shapes between Visio and Omnigraffle. If you have a better way, or another good Omnigraffle stencil site, let me know!
