Q - question

The degrees of freedom (DOF) for Inventor assembly components.

A - answer Each unconstrained component in an Inventor assembly has 6 degrees of freedom (3 for translation and 3 for rotation in each axis XYZ).

You can find the basic information about the degees of freedom through the DOF icons via the ribbon View > Visibility > Degrees of Freedom in the Inventor assembly environment (green cubes indicate a constraint to an underconstrained component - it is highlighted when you hoover over a cube).

A more detailed analysis of the degrees of freedm can be displayed through the function Assemble > Productivity > Degree of Freedom Analysis. This function displays a table with all assembly components together with the number of their degrees of freedom (translation + rotation). You can check the Animate option to animate the component DOF. A fully constrained assembly has zero DOF.
