Assemblies and components, including connections and custom parts, now have a View angle option on the contextual toolbar.
You can show the selected assembly or component in different view angles by selecting a top, back, right, bottom, front, or left view.
The view angles are based on the assembly main part's coordinate system. Because of that, the objects may not always appear as expected when you select a view angle. Note that the full object is not always shown.
To return to the original 3D view, click the button in the middle of the view angle options.
