Fusion 360 Assembly Design 1 — Questions and Answers
Question 1: What is a 'Component' in Fusion 360?
- A self-contained design unit that can contain bodies, sketches, and joints (Correct answer)
- A 2D sketch profile used for features
- A rendering material assigned to a body
- A reference plane for assembly
Correct answer: A self-contained design unit that can contain bodies, sketches, and joints
A Component is Fusion 360's basic assembly unit — it has its own origin, can hold multiple bodies and sketches, and can be jointed to other components.
Question 2: Which joint type in Fusion 360 allows one component to rotate freely around a single axis?
- Revolute (Correct answer)
- Rigid
- Slider
- Cylindrical
Correct answer: Revolute
A Revolute joint constrains all translational degrees of freedom and allows only rotation around one specified axis.
Question 3: What does a 'Rigid' joint do in Fusion 360?
- Locks two components together with no relative motion (Correct answer)
- Allows sliding along one axis
- Allows rotation and translation
- Connects components with a spring force
Correct answer: Locks two components together with no relative motion
A Rigid joint removes all degrees of freedom between two components, making them move as one fixed unit.
Question 4: In Fusion 360 assemblies, what is the 'Ground' function used for?
- Fixes a component's position so it cannot move (Correct answer)
- Moves a component to the origin
- Deletes a component's joints
- Makes a component transparent
Correct answer: Fixes a component's position so it cannot move
Grounding a component anchors it to a fixed position in space, serving as the reference part that all others are assembled to.
Question 5: Which Fusion 360 command allows you to define where two components connect by specifying geometry on each part?
- Joint (Correct answer)
- As-Built Joint
- Rigid Group
- Contact Set
Correct answer: Joint
The Joint command lets you pick connection geometry (faces, edges, points) on two components to define their physical relationship.
Question 6: What is an 'As-Built Joint' in Fusion 360?
- A joint applied to components already positioned in space without repositioning them (Correct answer)
- A joint that rebuilds broken connections automatically
- A joint that requires mate conditions
- A joint only usable in the sheet metal environment
Correct answer: A joint applied to components already positioned in space without repositioning them
An As-Built Joint creates a joint between components based on their current positions, without snapping them to new geometry.
