Placed features are common engineering features that do not require a sketch when you create them with Autodesk Inventor. You usually provide only the location and a few dimensions.
Dialog boxes define values for placed features, such as the Hole dialog box.
The commands for placed features (fillet, chamfer, hole, thread, face draft, and shell,) are located on the Sketch and 3D Model tabs:
Places a fillet or round on selected edges loops, and features.
Breaks sharp edges. Removes material from an outside edge and adds material to an inside edge.
Places a specified hole in a part, optionally with thread.
Creates regular and tapered external and internal threads on cylindrical or conical faces.
Produces a hollow part with a wall thickness you define.
Creates a rectangular pattern of features.
Creates a circular pattern of features.
Mirrors different type of features across a plane.
