BIM Workbench/it

Introduzione
L'ambiente BIM è un ambiente aggiuntivo finalizzato all'implementazione completa degli strumenti Building Information Modeling (BIM) e del flusso di lavoro in FreeCAD. Attualmente assomiglia molto all'ambiente interno Arch. L'idea generale, tuttavia, è quella di lavorare come "meta workbench" e raccogliere in un unico luogo strumenti diversi di altri ambienti di lavoro utili per BIM e creare un flusso di lavoro che sia più conveniente, e sia facile da usare sia per gli utenti esperti di BIM provenienti da altri software come Revit o ArchiCAD che per i nuovi arrivati. Il workbench BIM presenta anche un paio di strumenti, che sono per lo più procedure guidate e strumenti di gestione, che si trovano sotto il menu Gestione.

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 and developed 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 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 build 3D BIM objects on top of it.

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

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 (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.

Annotation
Annotations are visual help objects that can be placed inside your model. They can be used to export your model directly to a 2D format like DXF, or reused when creating 2D views of your model with the TechDraw Workbench.
