Autodesk Inventor: Add/Subtract One Model from Another - Boolean Modifier/Operation

I am venturing into the world of 3D design, and 3D printing, by learning Autodesk Inventor. It is mechanical and methodical compared to other programs like Sketchup and Blender- and I was wondering if Inventor could merge models together, or use one model as a cutter for another model. I guess for applications like Blender, this function is called a boolean modifier (here's a video of that). Autodesk Inventor can do something similar- here are the steps.

Autodesk Inventor: How To Import STL Files

My goal is to learn how to design in 3D with software like Blender, but I am getting into the swing of 3D printing by learning the basics of Autodesk Inventor. A lot of people share their designs on Thingiverse, where you can download the designs and examine them. Autodesk Inventor can import .STL files, but you it doesn't appear you can do anything with them, let alone modify them... but there is a plugin.

Universal Construction Toy Parts

A year ago now, news circulated the web of a guy who made a universal toy parts set that allowed parts from different brands to be mixed. I didn't pay much attention to 3D printing before seeing this news. I could guess that a lot of the 3D toy part designs may have come about because of this guys work. The "Universal Construction Kit" parts are on Thingiverse.

Objective: Learn 3D design, and eventually animation.
