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

The Bottom-Up method of creating an assembly is centered around designing individual components separately before combining them to form a complete assembly. This approach allows for greater flexibility and control over each part's design, as each component can be developed with its specifications, details, and functionality in mind. Once each part has been finalized, they are brought together in the assembly, allowing the designer to focus on the interface and interrelationship of the components, ensuring they fit and function properly together.

This method contrasts with a more integrated approach, where all parts might be considered and created simultaneously, which can lead to complexities and difficulties in managing the overall design. By starting with individual parts, designers can iterate and refine each segment before seeing how they fit within the larger assembly, ultimately resulting in a more cohesive and functional final product.
