Fusion 360 Assembly Design 2 — Questions and Answers
Question 1: What does the 'Cylindrical' joint type allow in Fusion 360?
- Rotation around and translation along the same axis simultaneously (Correct answer)
- Rotation around two axes
- Translation along one axis only
- Rotation around one axis only
Correct answer: Rotation around and translation along the same axis simultaneously
A Cylindrical joint allows both rotation around and translation along a single axis, simulating a bolt sliding and spinning in a hole.
Question 2: In Fusion 360, what is a 'Rigid Group'?
- A group of components that move together as if bonded, while preserving individual joints (Correct answer)
- A locked set of sketch geometry
- A collection of bodies merged into one
- A group folder in the browser
Correct answer: A group of components that move together as if bonded, while preserving individual joints
A Rigid Group links multiple components so they translate and rotate as one unit while keeping each component's joints intact.
Question 3: Which Fusion 360 tool checks for component interference in an assembly?
- Interference (Correct answer)
- Clearance
- Contact Sets
- Motion Study
Correct answer: Interference
The Interference command detects where two components occupy the same space, highlighting overlapping volumes.
Question 4: What is the purpose of 'Contact Sets' in Fusion 360 assemblies?
- Defines which pairs of components can physically collide during motion simulation (Correct answer)
- Merges component surfaces together
- Sets material contact properties for FEA
- Defines electrical contact points
Correct answer: Defines which pairs of components can physically collide during motion simulation
Contact Sets specify component pairs that should prevent interpenetration during motion simulation, enabling realistic collision behavior.
Question 5: How do you make one component dependent on another's movement in Fusion 360?
- By applying a joint between them (Correct answer)
- By nesting one inside the other in the browser
- By using the Align command
- By grouping them in the timeline
Correct answer: By applying a joint between them
Joints define the kinematic relationship between components, so one component's motion drives or constrains another's.
Question 6: Which Fusion 360 joint allows rotation about one axis and translation along a different axis?
- Planar (Correct answer)
- Cylindrical
- Ball
- Slider
Correct answer: Planar
A Planar joint allows both rotation about an axis perpendicular to a plane and translation within that plane.
