You can model multiple bodies in the assembly part file and later push these solids into their own component part files by using the _______ command.

The command that allows you to model multiple bodies in the assembly part file and subsequently push these solids into their own component part files is the New Component command. This command is specifically designed for creating individual components from bodies that have been modeled in an assembly. When you have created multiple bodies within an assembly file, the New Component command provides an intuitive way to separate these bodies into distinct components, allowing for better organization and management of parts in the assembly.

This capability is particularly useful in design workflows where multiple parts are being developed in tandem and need to be easily transferred into individual files for further modifications or manufacturing processes. Other options like New Part and Create Body do not directly address the need to take existing bodies in an assembly and turn them into separate component part files. The term Push out is not a standard command in this context.
