建筑模块
简介
建筑工作台为FreeCAD提供了一种现代化的建筑信息模型(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。
由于建筑工作台要利用2D对象来构建其建筑物对象,因此,它导入了底图工作台(Draft Workbench)中的所有工具。除此以外,建筑工作台亦可用如零件工具台(Part)与零件设计工作台(PartDesign)所创建的对象。
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.

Section Plane: Adds a section plane object to the document
Axis tools: The Axis tool allows you to places a series of axes in the current document.
Axis: Adds a 1-direction array of axes to the document
Axes system: Adds an axes system composed of several axes to the document
Grid: Adds a grid-like object to the document

Space: Creates a space object in the document
Stairs: Creates a stairs object in the document
Panel tools: Allows you to build all kinds of panel-like elements.
Panel: Creates a panel object from a selected 2D object
Panel Cut: Creates a 2D cut view from a panel introduced in version 0.17
Panel Sheet: Creates a 2D cut sheet including panel cuts or other 2D objects introduced in version 0.17

Equipment: Creates an equipment or furniture object
Pipe tools introduced in version 0.17
Pipe: Creates a pipe introduced in version 0.17
Pipe Connector: Creates a corner or tee connection between 2 or 3 selected pipes introduced in version 0.17
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
Survey: Enters or leaves surveying mode
Utilities
These are additional tools to help you in specific tasks.
Component: Creates a non-parametric Arch component
- File:Arch cloneComponent.png Clone component:
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.
Preferences
Preferences: preferences for the default appearance of walls, structures, rebars, windows, stairs, panels, pipes, grids and axes.
