Lesson 3-4: Fusion Basics & Pen Holder Creation

Goals

Learn the basic operations of Fusion (viewport controls, solid creation, sketching)
Design and model a pen holder, then export as .f3d and .stl files
(Optional) Design an original pen holder and 3D print it

Part 1: Fusion Basics

1-1. Starting Fusion & Mouse Controls

Launch Fusion and create a new project
Practice basic mouse controls:
- Middle-click drag: Pan the viewport
- Scroll wheel: Zoom in/out
- Shift + middle-click drag: Orbit the viewport
- Click the ViewCube (top-right) to snap to standard views

1-2. Creating Cuboids & Cylinders

Create a cuboid:

Select Solid → Create → Box
Click the origin as the base point
Enter: Width 25 mm, Depth 25 mm, Height 25 mm

Create a cylinder:

Select Solid → Create → Cylinder
Enter: Diameter 50 mm, Height 15 mm

1-3. Combine & Cut Bodies

Combine: Merge two bodies into one using Solid → Modify → Combine (Join operation)
Cut: Create holes by combining with Cut operation

1-4. Feature Timeline & Editing

Double-click any feature in the timeline to edit its parameters
Changes propagate automatically to subsequent operations

1-5. Sketching

Draw 2D shapes using Line, Spline, Circle, Arc tools
Use Trim, Offset, Mirror, Circular Pattern, Rectangular Pattern
Use Extrude to convert sketches into 3D bodies

1-6. File Export

.f3d: Fusion native format (editable)
.stl: Mesh format for 3D printing

Part 2: Pen Holder Creation

Create a box: 75 × 70 × 100 mm
Hollow it out with 2 mm wall thickness using Offset + Extrude Cut
Cut the front at an angle (45 mm down, 35 mm across)
Engrave text on the front face (1 mm depth)
Add fillets to edges
Export as .f3d and .stl
