Yes. Very easy actually, except for texturing. Stage3D lets you do realtime 3D on mobile devices, the web, desktop, etc.
I use a framework called Flare3D mostly. It comes with a 3dsmax 3d plugin. It installs custom materials in 3dsmax (2010 and above) and you need to texture your object using them (I find) as the built in standard material converter doesn't work too well. It also adds a menu item to 3dsmax that lets you export your object in a format called f3d.

Grab the YellowPlanet tutorial (Flash Builder) to see how easy it is to use. After you set up a basic scene, the default nature is just to show the 3d object and allow you to rotate/zoom around the object without you coding it at all.
