How do you create an assembly using the Bottom-Up method?

The Bottom-Up assembly method involves creating individual parts separately before integrating them into a larger assembly. This process emphasizes the design of each component independently, ensuring that each part is fully developed and optimized before being brought together within the assembly.

By creating the parts separately, designers can focus on each component's functionality, dimensions, and geometry without the distractions of the assembly environment. Once all individual parts are finalized, they can be added to the assembly in a systematic manner, typically using assembly constraints to define their relationships and interactions with each other.

This method is particularly useful for complex assemblies where parts may undergo several modifications before they are finalized. It allows for easier revisions and testing of individual parts without affecting the overall assembly until each component is properly integrated. In contrast, options involving creating parts within the same file or linking them do not fit the Bottom-Up approach as closely, as they either merge the creation and assemblage process or imply a less modular method of assembly design.
