After you create a part instance or a model instance, you apply a succession of position constraints and positioning operations to position it relative to other instances in the global coordinate system. This section describes the tools that Abaqus/CAE provides to position and constrain part and model instances. This section also describes how you can replace a part instance. The following topics are discussed:

• “The position tools in the Assembly module,” Section 13.5.1

• “How the position constraint methods differ,” Section 13.5.2

• “How conflicts can arise between position constraints, translations, and rotations,” Section 13.5.3

• “Positioning a part or model instance using the Translate To tool,” Section 13.5.4

• “Replacing a part instance,” Section 13.5.5
