This simple tutorial will walk through creating a pipe in the Part Design Workbench using additive and subtractive tools. The tutorial is meant to teach the Additive and Subtractive tools in FreeCAD. There are industry standard ways to accomplish a pipe, this is not a tutorial on industry standards. This tutorial aims to familiarize the learner with the FreeCAD interface.
