简介

建筑工作台为FreeCAD提供了一种现代的建筑信息模型（building information modelling） (BIM)工作流程，它支持的特性有完全参数化的建筑实体，如墙、结构构件、屋顶、窗口、台阶、管道与家具。建筑工作台还支持工业基础分类（industry foundation classes） (IFC) 数据，以及联合TechDraw工作台制作2D平面布置图。

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.

Tools

These are tools for creating architectural objects.

• Wall: Creates a wall from scratch or using a selected object as a base
• Structural element: Creates a structural element from scratch or using a selected object as a base

• Rebar tools: The Reinforcement Addon augments the Arch Workbench Structures.
  • Straight Rebar: Creates a Straight reinforcement bar in a selected structural element
  • UShape Rebar: Creates a UShape reinforcement bar in a selected structural element
  • LShape Rebar: Creates a LShape reinforcement bar in a selected structural element

• Material tools: The Material tools allows to add materials to the active document.
  • Material: Creates a material and attributes it to selected objects, if any
  • Multi-Material: Creates a multi-material and attributes it to selected objects, if any introduced in version 0.17
• Schedule: Creates different types of schedules

Modification tools

These are tools for modifying architectural objects.

• Cut with plane: Cut an object according to a plane.
• Add component: Adds objects to a component
• Remove component: Subtracts or removes objects from a component

Utilities

These are additional tools to help you in specific tasks.

• 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
• File:Arch MergeWalls.png 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...:
• File:Arch ToggleSubs.png Toggle Subcomponents: Shows or hides the subcomponents of an Arch object.
