From the outset, Revit was intended to allow architects and other building professionals to design and document a building by creating a parametric three-dimensional model that included both the geometry and non-geometric design and construction information, which is also known as Building Information Modeling or BIM Eastman C.
At the time, several other software packages—such as ArchiCAD and Reflex—provided a three-dimensional virtual building model, and let the user control individual components via parameters parametric components. Two key differences in Revit were that users created parametric components in a graphical "family editor" rather than a programming language, and the model captured all relationships between components, views, and annotations so that a change to any element automatically propagated to keep the model consistent.
The concept of bi-directional associativity  between components, views, and annotations was a distinguishing feature of Revit for many releases. The ease of making changes inspired the name Revit, a contraction of Revise-Instantly. At the heart of Revit is a parametric change propagation engine that relied on a new technology, context-driven parametrics, that was more scalable than the variational and history-driven parametrics used in mechanical CAD software.
The company was renamed Revit Technology Corporation in January Revit version 1. The software progressed rapidly, with version 2. Licensing was controlled by an entirely automatic process, an innovation at a time when human intervention and manual transmission of authorization codes was required to buy other types of design software. Autodesk has released several versions of Revit since After the release Revit Building was renamed Revit Architecture.
In  Revit LT  became the newest version of Revit on the market. It is a light version of Revit with a number of features such as rendering and multi user environments removed. In , Autodesk released the feature limited Revit LT for the entry level market alongside the full featured Revit Use and Implementation[ edit ] Revit can be used as a very powerful collaboration tool between different disciplines in the building design sphere. The different disciplines that use Revit approach the program from unique perspectives.
Each of these perspectives is focused on completing that discipline's task. Companies that adopt the software first examine the existing work flow process to determine if such an elaborate collaboration tool is required.
A recent addition to use cases and implementation is the Apache Licensed Dynamo graphical programming interface. Dynamo is similar to and takes inspiration from the Grasshopper visual programming language and environment for Rhino. In addition to the node based interface Dynamo can be scripted with the Design Script language and Python. Modeling[ edit ] The Revit work environment allows users to manipulate whole buildings or assemblies in the project environment or individual 3D shapes in the family editor environment.
Modeling tools can be used with pre-made solid objects or imported geometric models. However, Revit is not a NURBS modeller and also lacks the ability to manipulate an object's individual polygons except on some specific object types such as roofs, slabs and terrain or in the massing environment. Revit includes categories of objects 'families' in Revit terminology. These fall into three groups: Revit families can be created as parametric models with dimensions and properties.
This lets users modify a given component by changing predefined parameters such as height, width or number in the case of an array. In this way a family defines a geometry that is controlled by parameters, each combination of parameters can be saved as a type, and each occurrence instance in Revit of a type can also contain further variations. For example, a swing door may be a Family. It may have types that describe different sizes, and the actual building model has instances of those types placed in walls where instance-based parameters could specify the door hardware uniquely for each occurrence of the door.
Due to the copyright nature of project work, it is rare and impractical to be able to buy fully 3D modelled Revit project models. Indeed as most projects are site specific and bespoke, obtaining an existing model is in many instances unsuitable. However, there are circumstances where new practices or students that are training to learn Revit, do have a need to refer to completed models.
Sources for these are limited, however they can be purchased at websites like BIMGallery and downloaded from websites like GrabCad. In Dynamo  was released in beta form allowing first glimpses of directly programming the behavior of hosted components through a drag and drop node interface.
This is similar to the way the visual programming language Grasshopper 3d works on objects in Rhinoceros 3D. This is accomplished by either using the premade model, wall, floor, etc. Revit comes with a plethora of predefined materials, each of which can be modified to the user's desires.
The user can also begin with a "Generic" material. With this, the user can set the rotation, size, brightness, and intensity of textures, gloss maps also known as shinemaps , transparency maps, reflection maps , oblique reflection maps, hole maps, and bump maps , as well as leaving the map part out and just using the sliders for any one or all or none of the aforementioned features of textures.
Cloud-based rendering with the experimental plug-in dubbed Project Neon, located on Autodesk Labs is in the beta phases and allows for the user to render their images through their Autodesk account instead of locally through their own computers. Revit models may also be linked directly into Autodesk 3ds Max release and later for more advanced rendering and animation projects with much of their material and object information maintained.
Support details What is Revit? Revit is a multi-discipline BIM software with toolsets for architectural design, MEP and structural engineering, as well as construction. With this application, you can even collaborate seamlessly with every member of your team, whether they are using the same platform or not because of its solid interoperability. Other than that, the solution enables multiple project coordinators to manage tasks and centrally shared models to facilitate streamlined collaboration.
Revit lets you communicate and express your ideas effectively to your colleagues and project owners too. The software assists you in that regard by giving you tools you can utilize in creating impactful 3D visuals. Overview of Revit Benefits Multi-Disciplinary Tools Revit is an economical yet powerful solution for a varied team composed of architects, engineers, and construction professionals.
The platform has tools expressly crafted to meet the needs of everyone involved in building a structure that is pleasing to the eyes with a strong integrity. Immersive Models Rather than presenting flat images to your collaborators and clients, you can give them an immersive presentation.
Revit helps you achieve that through its one-click 3D modelling tool that transforms your design into affecting visualizations. Detailed Visualizations It is not just your architects who can drill down into the finest details with Revit—your engineers and construction team can too.
When you connect the platform with compatible Autodesk solutions, you can create more informative models that can assist the team in the structural fabrication process. Documented Images Aside from enabling you and your team to create eye-catching designs, Revit also helps your unit to generate helpful documentation for your models.
With this feature, you are able to provide your collaborators with every piece of information they need for them to build to specifications. Interoperable Platform Revit plays well with files produced using other solutions.
Because of this, you can work seamlessly with colleagues who prefer different platforms but use the same file extensions. This way, you can complete projects without the hassle of transforming files into compatible formats. Moreover, Revit supports multiple project contributors. This enables everyone on the team to access the necessary work files for them to finish their tasks.
This results in smoother coordination and reduces clashing incidences. Overview of Revit Features.
