Fusion 360 Sketching and Constraints 1 — Questions and Answers
Question 1: Which constraint in Fusion 360 forces two lines to remain at 90 degrees to each other?
- Perpendicular (Correct answer)
- Parallel
- Tangent
- Coincident
Correct answer: Perpendicular
The Perpendicular constraint forces two lines or curves to meet at a 90-degree angle.
Question 2: What does the 'Fix/UnFix' constraint do in Fusion 360 Sketch mode?
- Locks a sketch point or entity to its current position (Correct answer)
- Merges two sketch points together
- Makes a line construction geometry
- Deletes the selected entity
Correct answer: Locks a sketch point or entity to its current position
Fix/UnFix pins a sketch point or entity to a specific location so it cannot be moved during edits.
Question 3: In Fusion 360, what color indicates that a sketch is fully constrained?
- Black (Correct answer)
- Blue
- Red
- Yellow
Correct answer: Black
Sketch entities turn black when the sketch is fully constrained, meaning no degrees of freedom remain.
Question 4: Which Fusion 360 sketch tool creates a three-point arc?
- 3-Point Arc (Correct answer)
- Center Point Arc
- Tangent Arc
- Fillet
Correct answer: 3-Point Arc
The 3-Point Arc tool defines an arc by specifying its two endpoints and one point on the arc.
Question 5: What is the purpose of 'Construction Geometry' in Fusion 360 sketches?
- To use lines as references without contributing to the sketch profile (Correct answer)
- To create solid features from sketch lines
- To export sketches to DXF format
- To apply materials to sketch entities
Correct answer: To use lines as references without contributing to the sketch profile
Construction geometry acts as reference lines that help define the sketch but are not used to create features.
Question 6: Which command converts a regular sketch line to a construction line in Fusion 360?
- Normal/Construction toggle in the toolbar (Correct answer)
- Change Entity Type
- Convert to Reference
- Toggle Visibility
Correct answer: Normal/Construction toggle in the toolbar
Selecting an entity and clicking the Normal/Construction button in the sketch toolbar switches it to construction geometry.
