It's best practice to Create Components for each part. Typically this is best to do as you're creating, not after but things happen.
We need each body to be converted to a component to speed up our nesting and quoting process. To do so, the quickest way if you haven't done this while modeling is:
- Shift-select Bodies in the Tree
- Right Click on any of the selected bodies
- Select "Create Components from Bodies"
- Bonus - Rename Each Item something useful
