Fusion 360 3D Modeling Features 1 — Questions and Answers
Question 1: What does the Extrude command do in Fusion 360?
- Extends a 2D sketch profile into a 3D solid or surface (Correct answer)
- Rotates a profile around an axis
- Sweeps a profile along a path
- Scales a body in all directions
Correct answer: Extends a 2D sketch profile into a 3D solid or surface
Extrude takes a closed 2D sketch profile and pushes it linearly to create a 3D solid, cut, or surface.
Question 2: Which Fusion 360 feature creates a solid by rotating a sketch profile around an axis?
- Revolve (Correct answer)
- Sweep
- Loft
- Extrude
Correct answer: Revolve
The Revolve command generates a 3D body by spinning a sketch profile around a specified axis by a given angle.
Question 3: What is the purpose of the 'Shell' command in Fusion 360?
- Hollows out a solid body by removing one or more faces and creating a thin-walled shell (Correct answer)
- Creates a protective outer layer on a body
- Generates a mesh from a solid
- Applies a surface texture to a body
Correct answer: Hollows out a solid body by removing one or more faces and creating a thin-walled shell
The Shell command removes selected faces and offsets the remaining surfaces inward to create a hollow part with uniform wall thickness.
Question 4: In Fusion 360, what does a 'Fillet' operation do to an edge?
- Rounds the edge with a smooth curved transition (Correct answer)
- Creates a chamfer at 45 degrees
- Extends the edge outward
- Splits the edge into segments
Correct answer: Rounds the edge with a smooth curved transition
A Fillet rounds a sharp edge by replacing it with a smooth arc of a specified radius.
Question 5: Which Fusion 360 command cuts material from a body along a specified plane?
- Split Body (Correct answer)
- Shell
- Cut Extrude
- Chamfer
Correct answer: Split Body
Split Body divides a solid body into two separate bodies by cutting it along a face, plane, or surface.
Question 6: What is the difference between 'Join', 'Cut', and 'Intersect' in the Extrude dialog?
- Join adds material, Cut removes material, Intersect keeps only the shared volume (Correct answer)
- Join merges bodies, Cut mirrors bodies, Intersect projects bodies
- Join scales bodies, Cut rotates bodies, Intersect offsets bodies
- They all perform the same operation with different names
Correct answer: Join adds material, Cut removes material, Intersect keeps only the shared volume
Join adds the extruded volume to the existing body, Cut subtracts it, and Intersect retains only the region where both volumes overlap.
