BIM Workbench

Introduction
The BIM workbench is an external workbench aimed at implementing complete Building Information Modeling (BIM) tools and workflow in FreeCAD. It is an extension and currently looks much like the built-in Arch Workbench. The general idea, however, is to work as a "meta workbench", and gather in one place different tools from other workbenches that are useful to BIM, and create a workflow that is more convenient, easy and user-friendly to both experienced BIM users coming from other software like Revit or ArchiCAD and newcomers alike. The BIM workbench also features a couple of tools on its own, that are mostly wizards and management tools, located under the Management menu



Installing
The BIM workbench is not bundled with the default FreeCAD package, but can easily be installed via menu Tools -> Addons Manager. The BIM workbench code is hosted on github and can also be installed manually by copying it into FreeCAD's MOD directory. The BIM workbench is a work in progress, and will change often. Be sure to update it regularly!

Getting started
Upon starting the BIM workbench for the first time, a welcome dialog is shown, giving a quick overview of how the workbench works, and allowing the user to start an in-game tutorial. The welcome dialog is also available in the help menu. When the welcome screen is closed, the BIM setup dialog will be shown, that allows the user to quickly set some of the most common BIM-related preferences of FreeCAD without the need to browse through the full FreeCAD preferences pages.

The BIM project setup tool allows you to quickly setup a BIM project by filling some basic information about your project. You can then, for example, use the different 2D drafting tools to sketch guidelines and baselines, then use the different 3D modeling tools to build 3D BIM objects on top of it.

Tools
The BIM workbench gather tools from several other FreeCAD workbenches, mainly Draft, Arch and Part, roughly reorganized in three categories: 2D drafting tools, 3D modeling tools, annotation and modification tools. Additionally, if such addons are installed, tools from Reinforcement (extra reinforcing bar tools), Fasteners (bolts and screws) and Flamingo (metal structure and piping tools).

The BIM workbench also adds a couple of items in the status bar of FreeCAD, and a couple of context menu items, accessible by right-clicking in the 3D view or in the tree view.
