Which command in an assembly allows you to create assembly relationships between selected parts?

The appropriate command for creating assembly relationships between selected parts is the Assemble command. This command is fundamental in Solid Edge as it initiates the process of establishing relationships that govern how components interact within an assembly. When you select parts and invoke the Assemble command, you can define how these components fit together functionally and spatially by applying specific relationships, such as mate, align, or other types of constraints.

Using the Assemble command, designers can ensure that parts move relative to one another in a controlled manner, which is essential for developing accurate assemblies and mechanisms. It sets the framework for the assembly, allowing further detailing and refinement of relationships as needed. Understanding this command is vital for effective assembly design and manipulation in Solid Edge, enhancing both the precision and functionality of the models created.
