Arch Module/zh-cn

简介
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.
