I’m excited to share a new Visio stencil set for 2014 that I’ve created which contains some popular shapes for VMware Horizon View, Workspace and vSphere. You can download the Visio Stencils here: http://ray.is/visio. These are not official VMware stencils, but have been created from existing external content (thanks to Maish Saidel-Keesing at TechnoDrone) in addition to using Adobe PhotoShop and pulling images from public PDF documentation.
I think the way to go with diagrams and visual content creation is to use Adobe PhotoShop CS6 Extended. It has excellent 3D capabilities and (time permitting) you can create some really nice icons and shapes for your blogs, presentations or whitepaper. PhotoShop CS6 isn’t cheap, although if you buy a Mac then Apple will sell it at £169 for student and teacher editions.
I hope you enjoy using the Visio stencils!
