You can see the Degrees of Freedom of the parts in the assembly by using the “Show Degrees of Freedom” command in the Assemblies Ribbon Bar.
Activate the “Show Degrees of Freedom” command then click on the part. The arrows that simulate free moving directions will be simulated in the graphics window. (Shown in the figure)
Tip: To hide arrows on the screen; right click on the graphics window then click on “Refresh” from the opening list.
Note: In the older versions these arrows are not disappeared even if refresh command is used. You can clean these arrows by using the “Regenerate” command in the work view.
