What is an 'Assembly Joint' used for?

An Assembly Joint is a critical feature in Autodesk Inventor used to define the relative motion between components in an assembly. When specifying joints, you indicate how parts will behave concerning one another, such as rotation, sliding, or fixed positions. This allows for accurate simulations of mechanical movements and interactions, helping ensure that the assembly functions as intended in a real-world scenario.

The other options present functionalities that are not aligned with the purpose of Assembly Joints. For example, locking parts in place tends to refer to constraints or fixed positions, while combining parts into a single unit involves different modeling processes. Creating an assembly from standard parts involves a separate methodology, focusing more on cataloging and organizing components for assembly rather than defining their movement. Thus, the primary role of an Assembly Joint is pivotal in managing and simulating the motion of parts within an assembly.
