Briefly explain how bottom-up and top-down design approaches can be carried out using Rhino.

What will be an ideal response?

There are three approaches in designing an assembly of components: the bottom-up approach, the top-down approach, and the hybrid approach. The term bottom refers to the individual components of an assembly and top refers to the assembly as a whole. Using the bottom up approach, you construct a set of Rhino files to depict individual components of the assembly, start a new file for the assembly, and insert the component files into the assembly file. Using the top-down approach, you construct components in a Rhino file, construct block definitions for each component, export the block definitions as individual external files, and link the blocks to the exported files.
