What assembly method involves creating individual components in their own design files?

The assembly method that involves creating individual components in their own design files is referred to as Bottom-Up Assembly. This approach allows designers to construct a complex assembly by integrating pre-designed parts or components, each developed separately in their own files.

In Bottom-Up Assembly, each component is modeled independently, which enables creators to focus on the design and details of each part without being overwhelmed by the complexities of the entire assembly. Once each component is completed, they are then brought together in an assembly file where their relationships and interactions can be defined. This method promotes modular design, allowing for easier updates or revisions to individual components without affecting the entire assembly.

This is in contrast to other assembly methods like Top-Down Assembly, where the overall design comes first, and components are created based on the larger assembly, potentially leading to a more intricate and interconnected design process.
