It appears that the only way to get Sketchbook Designer is through a software suite. You can't download the suite as an education license, but you can download all of the software separately except Sketchbook Designer.
(I know that you can download Sketchbook Pro, but it doesn't include vector tools so it's no use to me)
Autodesk doesn't offer everyone of their products for free for educational use
this is the list
That's not very helpful, I'm familiar with that list of software. Plus, there's information left out of that list. For example, downloading Alias Design also includes Sketchbook Pro, which is not on that list. It did not say it would come with Sketchbook Pro, so I want to find if sketchbook designer is packaged with something else.
according to this: http://www.autodesk.com/products/autodesk-alias-pr
Alias Design 2014 does come with sketch book designer
according to this: http://usa.autodesk.com/adsk/servlet/item?siteID=1
2013 of Autodesk® SketchBook® Designer is part of the free student license but only 2013
I apologize for any confusion but the link above is out of date. Autodesk Sketchbook Designer is no longer offered through the Education Community or by individual purchase and is only available as part of a bundle when you purchase certain suites.
