Question 1

Which Inventor joint type removes all six degrees of freedom between two components?

Accepted Answer

Rigid

Answer

A Rigid joint locks the components together, leaving no relative motion.

Question 2

A Ball joint between two components leaves which degrees of freedom available?

Accepted Answer

Three rotational degrees of freedom

Answer

A Ball joint allows rotation about all three axes while preventing translation.

Question 3

Which joint type allows one rotation and one translation along the same axis, like a pin sliding in a bore?

Accepted Answer

Cylindrical

Answer

A Cylindrical joint permits rotation about and translation along a shared axis.

Question 4

What does a Planar joint allow?

Accepted Answer

Two translations in a plane and one rotation normal to it

Answer

A Planar joint keeps faces coplanar while allowing in-plane sliding and rotation about the normal.

Question 5

Which Angle constraint solution lets you define a third reference vector to prevent the angle from flipping direction?

Accepted Answer

Explicit Reference Vector

Answer

Explicit Reference Vector adds a z-axis reference so the angle direction stays predictable.
