Fusion 360 Sketching and Constraints

Question 1

Which constraint in Fusion 360 forces two lines to remain at 90 degrees to each other?

Accepted Answer

Perpendicular

Answer

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?

Accepted Answer

Locks a sketch point or entity to its current position

Answer

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?

Accepted Answer

Black

Answer

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?

Accepted Answer

3-Point Arc

Answer

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?

Accepted Answer

To use lines as references without contributing to the sketch profile

Answer

Construction geometry acts as reference lines that help define the sketch but are not used to create features.
