Arch Workbench/bg
Introduction
The Arch Workbench provides a modern building information modelling (BIM) workflow to FreeCAD, with support for features like fully parametric architectural entities such as walls, structural elements, roofs, windows, stairs, pipes, and furniture. It supports industry foundation classes (IFC) data, and production of 2D floor plans in combination with the TechDraw Workbench.
The Arch Workbench imports all the tools from the Draft Workbench, as it uses 2D objects to build its architectural objects. Nevertheless, Arch can also use solid objects created on other workbenches like Part and PartDesign.
The BIM functionality of FreeCAD is now progressively split into this Arch Workbench, which holds basic architectural tools, and the BIM Workbench, that you can install via the Addon Manager. This workbench adds a new interface layer on top of the Arch tools, with the aim to make BIM workflow in FreeCAD more intuitive and user-friendly.

Survey: Enters or leaves surveying mode
Utilities
These are additional tools to help you in specific tasks.
Component: Creates a non-parametric Arch component
Clone component: Produces Arch Components that are clones of selected Arch objects (not to be confused with Draft Clone)
Split Mesh: Splits a selected mesh into separate components
Mesh To Shape: Converts a mesh into a shape, unifying coplanar faces
Select non-solid meshes: Selects all non-solid meshes from the current selection or frm the document
Remove Shape: Turns cubic shape-based arch object fully parametric
Close Holes: Closes holes in a selected shape-based object
Merge Walls: Merge two or more walls
Check: Check if the selected objects are solids and don't contain defects
Ifc Explorer: Browse the contents of an IFC file
Toggle IFC Brep flag: Forces a selected object to be exported as an IfcFacetedBrep.
3 Views from mesh: Creates top, frontal and side views from a mesh.
Create IFC spreadsheet...: Creates a spreadsheet to store IFC properties of an object
Toggle Subcomponents: Shows or hides the subcomponents of an Arch object.
