What is the modeling concept where you model multiple bodies in the assembly part file and later push these solids into their own component part files?

The modeling concept where multiple bodies are created in an assembly part file and subsequently organized into individual component part files is known as top-down modeling. This approach allows designers to produce an overall system or assembly while considering the interrelationships of all components from the outset.

In top-down modeling, the assembly serves as a master file that captures the design intent and engineering requirements for all parts. By using this method, it becomes easier to ensure that all components fit together correctly and adhere to specific constraints or design rules, as all bodies are being developed in the same workspace and can be directly influenced by the assembly design. This strategy is particularly effective in design scenarios where parameters or features of one part may affect those of another, promoting a cohesive and integrated design process.

In contrast, other modeling strategies focus on building parts independently and then assembling them afterward, which does not leverage the same level of integration during the initial design phase.
