The Design Assistant includes:

• Selection Helper, which predicts and suggests which of your model’s entities you should select next.
• Mate Helper, which automatically inserts multiple instances of components into your assembly by recognizing and suggesting locations for replication.
• Sketch Helper, which recognizes existing sketch geometry in relation to surrounding geometry and suggests additional locations to place sketch entities.
• Smart Mate, which helps you create fully constrained mates; drag and hold a component into position, and Smart Mate will automatically create mates to surrounding components, recognizing the correct mating faces.
