This project aims to facilitate flexible implementation and usage of Rebaring in FreeCAD. The Reinforcement workbench provides tools for Reinforcement Generation and Detailing. This workbench provides an interface and presets for the creation of common rebar types. And tools to generate rebars bill of material, rebar shape cut list, bar bending schedule, and rebars drawing and dimension.

- FreeCAD (version >= 0.19): Installation guide
- Pillow: Required for generating BillOfMaterial when working in pure console mode without any gui element
Reinforcement workbench is available through the FreeCAD Addon Manager (menu Tools → Addon manager). It is called Reinforcement in the Addon Repository.
Like any other FreeCAD workbench, you can manually clone or download all the files from this repository in a "Reinforcement" folder inside your FreeCAD Mod directory as described here.

The documentation of this workbench is hosted on FreeCAD wiki pages and can be found here: https://wiki.freecadweb.org/Reinforcement_Workbench
Each rebar shape tool has two files, one is a python (AKA .py) file and the second is its respective UI (AKA .ui) file. For example: StraightRebar.py and StraightRebar.ui.
Let's continue with the straight rebar shape tool as the example. In the StraightRebar.py file, there are two functions:
- The
makeStraightRebar()function, this function creates straight rebar and adds new properties to the defaultRebarobject. - The
editStraightRebar()function, this function is used when we want to change new properties of the rebar object to take aRebarobject as input (which is created bymakeStraightRebarfunction).
Within the StraightRebar.py file we find the _StraightRebarTaskPanel class present. This class loads the UI (within the StriaghtRebar.ui file) in to a FreeCAD task panel. When a user clicks on the Apply or the Ok button, the makeStraightRebar function is executed and after that when the user wants to change the properties of Straight rebar then the editStraightRebar() function is executed.
We love contributions! We have collected notes on how to contribute to this project in CONTRIBUTING.md
