App Link

From FreeCAD Documentation

Introduction

An App Link, or formally an App::Link, is a type of object that references or links to another object, in the same document, or in another document. It is especially designed to efficiently duplicate a single object multiple times, which helps with the creation of complex assemblies from smaller subassemblies, and from multiple reusable components like screws, nuts, and similar fasteners.
