2.6.1 Revit

我們從Revit Architecture 的角度來(lái)考量Revit平臺(tái)。建筑設(shè)計(jì)中，Revit是BIM方面最知名的平臺(tái)也是目前市場(chǎng)上的領(lǐng)頭羊。它是由歐特克公司收購(gòu)一家創(chuàng)業(yè)公司的Revit之后，于2002年引入市場(chǎng)的。Revit是一款有著不同的編碼庫(kù)和文件架構(gòu)的完全獨(dú)立于AutoCAD的平臺(tái)。這里闡述的Revit是2011版本。Revit是一款綜合產(chǎn)品，包括Revit Architecture、Revit Structure、以及Revit MEP。Revit能在Windows操作系統(tǒng)上運(yùn)行，也能使用Windows BootCamp?- 插件在Mac系統(tǒng)上運(yùn)行。它能在32位和64位處理器以及各種版本的操作系統(tǒng)上運(yùn)行。

 

作為工具：Revit提供了一個(gè)易于使用的界面，每步操作和智能光標(biāo)都有拖拽提示。其操作菜單根據(jù)工作流進(jìn)行了很好的組織，而且它的操作菜單能把當(dāng)前系統(tǒng)環(huán)境中不可用的操作進(jìn)行灰顯。Revit的圖紙生成功能非常好；它的圖紙生成關(guān)聯(lián)性很強(qiáng)，所以很容易管理圖紙發(fā)布。它提供了圖紙與模型之間的雙向編輯功能，也支持構(gòu)件（如門、門配件等）和明細(xì)表之間的雙向編輯。Revit支持制作自定義參數(shù)化構(gòu)件和預(yù)定義構(gòu)件的自定義化。Revit用于定義構(gòu)件的規(guī)則已經(jīng)隨著每個(gè)版本的發(fā)布進(jìn)行了改良，并包含了三角函數(shù)。它可以在陣列中約束距離和角度以及構(gòu)件數(shù)量。它也支持參數(shù)之間的層次關(guān)系。因此，一個(gè)構(gòu)件能通過(guò)具有參數(shù)關(guān)系一組子構(gòu)件進(jìn)行定義。設(shè)置能約束組裝構(gòu)件布局和尺寸的全局參數(shù)是更加困難的。最新API的發(fā)布為外部應(yīng)用程序開(kāi)發(fā)提供了有力支持。

 

Revit有一個(gè)非常大的產(chǎn)品庫(kù)，特別是用于規(guī)范和設(shè)計(jì)構(gòu)件的Autodesk SEEK庫(kù)。它為大約850家不同的企業(yè)以及13750條不同的產(chǎn)品線（包括超過(guò)750種燈具）承載著信息。這些產(chǎn)品是由各種文件類型定義的：RVA、DWG、DWF、DGN、GSM、SKP、IES以及TXT。它們?cè)贛asterformat、Uniformat以及Omniclass Table 23 (產(chǎn)品)格式中都是可訪問(wèn)的。大約有六個(gè)其它網(wǎng)站都有BIM產(chǎn)品，其中Revit對(duì)象占主導(dǎo)地位。

 

作為平臺(tái)：作為BIM市場(chǎng)的引領(lǐng)者，Revit有最大的相關(guān)應(yīng)用程序組。有些是通過(guò)Revit的開(kāi)放API的直接鏈接，其它的則是通過(guò)IFC或者其它轉(zhuǎn)換格式。這些分別被記為（Dir）和（IFC）。DWF是另外一個(gè)Revit接口，記為（Dwf）。

2.6.1 Revit

We consider the Revit platform from the perspective of Revit Architecture. Revit is the best-known and current market leader for BIM in architectural design. It was introduced by Autodesk in 2002 after Autodesk acquired the Revit program from a startup company. Revit is a completely separate platform from AutoCAD, with a different code base and file structure. The version reviewed here is 2011. Revit is a family of integrated products that currently includes Revit Architecture, Revit Structure, and Revit MEP. It runs on Win- dows OS and on Macs, using the Windows BootCamp? plug-in. It runs on both 32- and 64-bit processors and versions of the OS.

As a tool: Revit provides an easy-to-use interface, with drag-over hints for each operation and smart cursor. Its menus are well organized according to workflow and its operator menus gray-out nonavailable actions within the current system context. Its drawing generation support is very good; its drawing production is strongly associative, so that drawing releases are easily managed. It offers bidirectional editing from drawings to and from the model, and also bidirectional editing from schedules for doors, door hardware, and the like. Revit supports the development of new custom parametric objects and customization of predefined objects. Its rule set for defining objects has improved with each release and includes trigonometric functions. It can constrain distances and angles and the number objects in an array. It also supports hierarchical relations of parameters. Thus, an object can be defined by using a group of sub-objects with parametric relations. It is more difficult to set up global parameters that can constrain assemblies of objects’ layout and sizes. The release of the current API provides good support for external application development.

Revit has a very large set of product libraries, particularly its own Autodesk SEEK library for specification and design objects. It carries information for about 850 different companies, and about 13,750 different product lines (including over 750 light fixtures). The products are defined in a mixture of file types: RVA, DWG, DWF, DGN, GSM, SKP, IES, and TXT. They are accessible from Masterformat, Uniformat, and Omniclass Table 23 (Products) for- mats. There are about a half-dozen other sites with BIM products, where Revit objects dominate.

As a platform: Revit, as the BIM market leader, has the largest set of asso- ciated applications. Some are direct links through Revit’s Open API and others are through IFC or other exchange formats. These are denoted (Dir) and (IFC), respectively. DWF is another interface for Revit, denoted (Dwf).

② Mechanical (with Revit MEP): Revit MEP (Dir), HydraCAD (fire sprin- klers), MagiCAD (mechanical design), QuantaCAD (mechanical laser scanning for as-builts), TOKMO (COBie facility operators handover— see Chapter 3)

③ Energy and environmental: Ecotect, EnergyPlus, IES all indirect, Green Building Studio via gbXML
