Introduction

The BIM workbench is an external workbench aimed at implementing complete Building Information Modeling (BIM) tools and workflow in FreeCAD. It 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 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.

Control bar

This toolbar, inherited from the Draft Workbench, offer a couple of controls to easily set up your work space for the next operations:

  • Working plane: Sets the working plane, either from a selected face or 3 vertices or working plane proxy, or by choosing from a menu if nothing is selected.
  • Construction mode: When turned on, new objects will be automatically added to a special construction group, which allows you to easily hide them later on
  • Line color: Sets the line color of next objects or of selected objects
  • Face color: Sets the face color of next objects or of selected objects
  • Line width: Sets the line width of next objects or of selected objects
  • Text size: Sets the font size of next texts or dimensions or of selected ones
  • Layer selector: Sets the current layer
  • Apply: applies the current line width, line color and face color to selected objects.

2D drafting

2D objects are commonly used as drafting aids, or to draw base lines and profiles to build BIM objects on. Most BIM objects such as walls or columns can be created from a selected 2D profile. They can also be used to draw symbols and annotations in your model. 2D objects will be drawn on the current working plane.

  • Sketch: Creates‎ a new sketch and enters sketch drawing mode
  • Line: Draws a line segment between 2 points
  • Wire: Draws a line made of multiple line segments (polyline)
  • Circle: Draws a circle from center and radius
  • Arc: Draws an arc segment from center, radius, start angle and end angle
  • Ellipse: Draws an ellipse from two corner points
  • Polygon: Draws a regular polygon from a center and a radius
  • Rectangle: Draws a rectangle from 2 opposite points
  • BSpline: Draws a B-Spline from a series of points
  • Cubic Bezier Curve: draws a Bezier curve of third degree by dragging two points.
  • Bezier Curve: Draws a Bezier curve from a series of points
  • Point: Inserts a point object

Annotation

Annotations are visual helper 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.

  • Text: Draws a multi-line text annotation
  • ShapeString: The ShapeString tool inserts a compound shape representing a text string at a given point in the current document
  • Dimension: Draws a dimension annotation
  • Label: Places a label with an arrow pointing to a selected element introduced in version 0.17
  • Axis: Creates a 1-direction series of axes. Can also be used to create individual axes
  • Axes system: Combines 2 or 3 axes into a 2- or 3-dimensional axes system
  • Axis and grid tools: Grid: Creates a grid-like object that can be used as a base for assemblies like curtain walls or windows
  • Section Plane: Adds a section plane object to the document. Section planes define 2D views such as plans, sections and elevations

3D / BIM modeling

3D and BIM objects are the real-world elements that will compose your BIM project.

  • Project: Creates a project
  • Site: Creates a site
  • Building: Creates a building
  • Building Part: Creates a building part. Building parts are commonly used to make levels/storeys or any kind of assembly of other BIM objects
  • Space: Creates a space object
  • Reference: Links objects from another FreeCAD file into this document
  • Wall: Creates a wall from scratch or from a selected object such as a baseline or footprint
  • Column: Creates a structural element in column mode (1-point placement) from a preset or using a selected object as a base profile
  • Beam: Creates a structural element in beam mode (2-point drawing) from a preset or using a selected object as a base profile
  • Slab: Creates a structural element using a selected object as a base profile
  • Rebar: Creates a reinforcement bar in a selected structural element using a sketch. Requires the Reinforcement addon
  • Window: Creates a window object using a window preset
  • Door: Creates a window object using a door preset
  • Pipe tools: Creates pipes and corner or tee connection between 2 or 3 selected pipes
