本软件是由Graphisoft机构出品的ArchiCAD三维建筑设计软件V21.4004 WIN版，大小：4.9 GB，支持Win64位系统，语言：英语。
作为全球领先的建筑设计三维一体化软件解决方案的提供者，GraphiSoft 一贯倡导虚拟建筑模型（3D- Virtual Building）设计理念，并将此理念贯穿于产品设计的始终。
ArchiCAD 是GraphiSoft 公司的旗舰产品，也是当今世界上最优秀的三维建筑设计软件。其基于全三维的模型设计，拥有强大的剖/立面、设计图档、参数计算等自动生成功能，以及便捷的方案演示和图形渲染，为建筑师提供了一个无与伦比的"所见即所得"的图形设计工具。ArchiCAD 内置的 PlotMaker 图档编辑软件使出图过程与图档管理的自动化水平大大提高，而智能化的工具也保证了每个细微的修改在整个图册中相关图档的自动更新，大大节省了传统设计软件大量的绘图与图纸编辑时间，使建筑师能够有更多的时间和精力专注于设计本身，创造出更多激动人心的设计精品。
同时对于各设计企业来说，ArchiCAD 不仅仅意味着设计生产力的提升，还能够帮助企业更为高效科学地管理与检索设计文档，完善企业的设计标准，提高知识产品的使用价值。
ArchiCAD 完善的团队协作功能为大型项目的多组织、多成员协同设计提供了高效的工具，团队领导者可以根据不同区域、不同功能、不同建筑元素等属性将设计任务分解，而团队成员可以依据权限在一个共同的可视化项目环境里准确无误的完成协同工作；同时ArchiCAD 创建的三维模型，通过IFC标准平台的信息交互，可以为后续的结构、暖通、施工等专业，以及建筑力学、物理分析等提供强大的基础模型，为多专业协同设计提供了有效的保障。

ARCHICAD 21 BUILD 4004 WITH ADDONS WIN
Innovation has been a key differentiator for ARCHICAD since the beginning. ARCHICAD 21 introduces the highly-anticipated Stair Tool, featuring GRAPHISOFT’s patent-pending Predictive Design™ technology. ARCHICAD 21 delivers a number of other, important functional improvements in the fields of visualization, OPEN BIM, performance and productivity making this version one of the strongest in GRAPHISOFT’s history.
As any drafter or architect knows, designing stairs is fraught with challenges. Not only do strict building standards complicate stair design, but iterations of a building’s structure mean there’s a tremendous amount of tedious reworking of the stair design each time a project is modified. In ARCHICAD 21, this has all changed. According to GRAPHISOFT, drafters will now have access to automated stair design tools that work in the background to create an optimal stair configuration that’s building specific. All users need to do now is create a polyline to guide the direction of the stairs and wait for the ARCHICAD stair algorithm to offer up stair design options. Once a stair design has been chosen, an associated railing can be added with a simple single-click operation that completes the climbing feature.
Beyond the time-saving stair tool, ARCHICAD 21 also features an upgraded CineRender engine, which can be used to create photorealistic images of building interiors and exteriors.
Element classification has also been enhanced in the new package as any ARCHICAD model can now be described as central BIM database that contains all project data. This new, flexible method for classification makes it possible to support and share any element of a national or corporate standard, making it easier for various partners and suppliers to interact with a design.
