A Hello World walkthrough using (1) Fusion 360 to create a cup geometry, and (2) Cura to slice the cup geometry for 3D printing.

Navigating the 3D Viewport
- 3D Viewpoint Shortcuts - cube on the top right; if you are ever lost, hit the home icon.
- Main UI (Axis) - Revolves around central axis
- Main UI (Hand) - Pans camera view in orthogonal directions (left/right/up/down)
- Visual Style - Useful for seeing through complex objects
Creating a Sketch
- Create Sketch (2D drawing in 3D world)
- Specify a Plane (convention is to use the XY plane
- Use the Circle action to draw a 50 mm circle
- You can specify units (cm, in, mm, etc...); default is mm.
- Edit by double-clicking on the dimension.
- Finish Sketch to return to the 3D environment
- Double-click on sketch to return to 2D environment
Naming your sketches is an excellent habit
Extruding a 3D Volume
- Use the Extrude (E) operation
- Drag the arrow handler or use the parameter UI
- Note different types of operation: New Body, Cut, New Component
- Extrude by 60 mm
Cutting 3D geometries
- Construct a new sketch on the top of the cylinder
- Activate the outer circle geometry from the layers panel
- Create a inner circle geometry
- Extrude inner circle geometry downward -- this will automatically select the "Cut" operation -- seen in red
- Cut 55 mm from the cylinder
Fillets
- Modify > Fillet
- Select edges
- Specify 1.5 mm radius
- Apply to the bottom edge as well
Appearance & Rendering
- Select body > Right-click > Appearance
- Drag and drop a material onto the body
- Switch to Render to view the material rendering under different lights
- Switch back to Sketch to select different appearances
Exporting and Slicing for 3D printing
- File > 3D Print
- Select STL, millimeter, uncheck Print to Utility
- Save in your file system
- Open Cura. adjust 3D printing parameters to your 3D printer's configuration
- Drag-and-drop STL file
- Rotate 3D model to reduce overhangs or need for support structure
- Use the Slice/Preview options to see the results of your parameters
- Save the .gcode file to a USB -- Plug the USB into your 3D printer and follow the dialogs to 3D print.
