You use the Assembly module to create and modify the assembly. The model contains only one assembly, which is composed of instances of parts from the model. Appendix C, “Using Additional Techniques to Create and Analyze a Model in ABAQUS/CAE,” of Getting Started with ABAQUS contains examples of how you use the Assembly module to create part instances and position them relative to each other in a global coordinate system. This chapter explains how you use the tools within the Assembly module to create the assembly. The following topics are covered:
