In the Viewport, in the Blueprint Editor, you can view and manipulate your Blueprint's components.

You can also manipulate a selected component by adjusting its values manually in the Details panel.
Selecting a component in the Component list selects that component in the Viewport too, and populates the Details panel with its property information.
You can use the transformation widgets in the Viewport to adjust the location, rotation, and scale of selected components. For more information about transformation widgets, see Interactive Transforms.
You can navigate in the Blueprint Editor's Viewport in the same ways in which you navigate in the Level Editor's Viewport. For more information, see Viewport Controls.
The View Menu
The View drop-down menu, in the Viewport's upper-left corner, has somewhat different options than the Level Editor's Viewport menus.
