BIM Workbench/en

Introduction
The BIM Workbench is an external workbench aimed at implementing complete Building Information Modeling (BIM) tools and workflow in FreeCAD. It can be installed from the Addon Manager.

The BIM Workbench is based on the built-in Arch Workbench, and both will probably be merged in the future. The BIM Workbench is a "meta workbench", intended to gather many useful tools from other workbenches in a single place, and create a workflow that is more convenient and user-friendly to both experienced BIM users and beginners. The BIM workbench also features some specific tools of its own, mostly wizards and management tools, located under the Management menu.

See FreeCAD BIM migration guide for a quick overview if you are already a user of another BIM application.

The developers of Draft, Arch and BIM also collaborate with the greater OSArch community, with the ultimate goal of improving building design by using entirely free software.



Installing
The BIM workbench is not bundled with the default FreeCAD package, but can easily be installed via the Addon Manager. Invoke it from. The BIM workbench code is hosted and developed on github and can also be installed manually by copying it into FreeCAD's directory.

Note

The BIM workbench is a work in progress, and will change often. Be sure to update it regularly! If you have the Python-Git module installed, the BIM workbench will automatically look for available updates at start, and display an icon in the status bar if an update is available.

The tools listed below might also not all be present if your FreeCAD version is not fully up-to-date. The BIM workbench should however work seamlessly on all FreeCAD versions, it will only drop the tools not available.

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 from the help menu. When the welcome screen is closed by clicking OK, 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 automatically build 3D BIM objects from them. A line, for example, can become a wall simply by selecting it and pressing the Wall button.

If you are used to another BIM application, check our BIM application compatibility table to get your marks when starting with FreeCAD.



The in-game tutorial is an easy way to quickly get on track with the BIM workbench.

Tools
The BIM workbench gather tools from several other FreeCAD workbenches, mainly Draft, Arch and Part, roughly reorganized in logical categories: 2D drafting, 3D modeling, annotation and modification tools. The manage category contains tools that are specific to the BIM workbench.

Additionally, if such addons are installed, tools from Reinforcement (extra reinforcing bar tools), Fasteners (bolts and screws), Flamingo/Dodo (metal structure and piping tools) and Parts Library are automatically included in the BIM workbench.

The BIM workbench also adds a series 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.

2D drafting
2D objects are commonly used as drafting aids, or to draw base lines and profiles to build BIM objects on. They can also be used to draw symbols and annotations in your model. Apart from sketches, that use their own coordinate system, 2D objects will be drawn on the current working plane.

External workbenches
FreeCAD workbenches are easy to program in Python, there are therefore many people developing additional workbenches outside of the FreeCAD main developers.

The external workbenches page has some information and tutorials on some of them, and the FreeCAD Addons project aims at gathering them and making them easily installable from within FreeCAD.

New workbenches are in development, stay tuned!
