For those of us who have a Leap Motion Controller or were thinking about getting one I finally stumbled upon an app that lets you control panning, zooming, rotating, and spinning for Parts, Drawings, and Assemblies within Solidworks (Thanks Nick Tanner!). The app known as Ossewa Solidworks Plug-In is purchasable through the Airspace Store and requires keyboard interaction only if you don't have a mouse with extra programmable buttons such as a gaming mouse. So far the app works great, but does not have part manipulation within an assembly yet. I feel it is definitely worth the $4. Happy modeling!!
