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.

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.
