BLENDER 3D MODELING SOFTWARE

Right now I'm learning Blender for 3D modeling work. Previously I used Rhino, SolidWorks, and Autodesk Inventor. Switching to Blender because a) people here use it, b) it's free, c) it works across platforms and d) it seems to be just as powerful as the non-free, Windows-only modeling software. 

Major shoutout to the awesome Wikibook that's making the transition easier:  Blender 3D: Noob to Pro. Highly recommend. 

Blender is not the kind of software you can launch into and grope about until you find your way. It's not like exploring an unfamiliar city. It's more like flying a spaceship. If you hop into the pilot's seat without knowing the fundamentals, you'll be lucky to ever get off the ground, and it'd take a miracle for you to reach your destination.
