Using Flux’s “Convert to Component” feature, you can quickly create a module from a group of components.
Overview
Modules are a great way to reuse portions of a circuit that stay consistent across multiple projects. If you find a group of components in one of your projects that could be reused in another design, you can use the "Convert to Component" function to quickly make it a module for future reuse.
Convert to Component
To convert a group of components into a single component:
Select all the components you want to convert.
Right-click and select "Convert to Component"
Adding Terminals
As mentioned, using the "Convert to Component" option turns a group of components into a module. As with any module, terminals are required to use it in a project.
If the group of components you've selected doesn't contain any terminals, the resulting module won't have any connections.
There are two ways to add terminals:
Add terminals to the group of components before using the "Convert to Component" option
After using the "Convert to Component" option, right click on the generated module and select "Open".
Once inside the module drag the terminals to the desired position and then publish the changes.
