What is a Subassembly in CAD design?

A Subassembly in CAD design refers specifically to a component that contains nested components. In this context, a subassembly acts as an individual part of a larger assembly, and it can be composed of multiple smaller components or parts, which can also include other subassemblies. This hierarchical structure allows for better organization and management of complex designs, making it easier to build, modify, and understand the relationships between different parts of an assembly.

By using subassemblies, designers can encapsulate functionality and streamline the assembly process. It allows for easier updates and modifications since changes made to the subassembly will reflect in the larger assembly without the need to rebuild everything from scratch. This modular approach enhances efficiency in CAD modeling and simplifies the overall design process.

Other choices may refer to important concepts in CAD, but they do not define what a subassembly specifically is within the context of assembling components in CAD software.
