Autodesk Revit develops information modeling software for architects, landscapers, civil, mechanical, electrical, and plumbing (MEP) engineers, designers, and contractors. The original software was developed by Charles River Software, founded in 1997, renamed Revit Technology Corporation in 2000 and acquired by Autodesk in 2002. The software allows users to design a building, structure and its components in 3D and annotate the model with 2D element drawings, and access building information from the building model database. Revit is a 4D building information modeling application that provides tools for planning and tracking the different phases of a building’s lifecycle, from concept to construction and subsequent maintenance and/or demolition.

Charles River Software was founded on October 31, 1997 in Newton, Massachusetts by Leonid Raiz and Irwin Jungreis, the principal developers of PTC’s Pro/Engineer mechanical design software, with the intention of bringing parametric modeling capabilities to the construction industry (formerly PTC). tried unsuccessfully to commercialize its recently acquired Reflex design software). With funding from venture capitalists Atlas Venture and North Bridge Venture Partners, Raiz and Jungreis hired several programmers and architects and began developing Revit in C++ on the Microsoft Windows platform. In 1999 they hired Dave Lemont as CEO and board members Jon Hirschtick, founder of SolidWorks, and Arol Wolford, founder of CMD Group.

The company was renamed Revit Technology Corporation in January 2000. Autodesk, best known for its AutoCAD product line, bought Revit Technology Corporation in 2002 for $133 million. The purchase enabled further research, software development and improvements.Thanks to the Revit platform, Autodesk is a major player in the BIM market, along with Tekla Structures Trimble, Bentley Systems and the Nemetschek Group (owner of the Graphisoft ArchiCAD BIM application and solutions, including Allplan and Vectorworks), among others.

Revit version 1.0 was released on April 5, 2000. The software developed rapidly, versions 2.0, 3.0, 3 appeared.1, 4.0 and 4.1 released August 2000; October 2000; February 2001; June 2001; Nov 2001; and January 2002.

Initially, the software was only offered for monthly rent, with no option to purchase it. Licensing was controlled through a fully automated process, which was an innovation at a time when purchasing other types of design software required human intervention and manual entry of authorization codes.

Autodesk released several versions of Revit after 2004. Revit Structure was introduced in 2005, followed by Revit MEP in 2006. When it was released in 2006, Revit Building was renamed Revit Architecture.

In 2011, Dynamo was released in beta, which provided the first glimpses of directly programming the behavior of hosted components through a drag-and-drop node interface. This is similar to how the Grasshopper 3D visual programming language works with objects in Rhinoceros 3D.

In 2012 Revit LT became the latest version of Revit on the market. Was it a version of Revit with limited functionality or a lite version that excluded features like rendering and multi-user environments? In 2013, Autodesk began rolling out rental licenses for some of its products, including Revit.

Starting with Revit 2013, the various disciplines have been combined into one product simply called Revit.

Autodesk sells various packages or “Industry Collections”; Revit is part of the AEC collection.

Revit is available in multiple languages: English, German, French, Spanish, Portuguese, Italian, Russian, Polish, Czech, Chinese, Japanese and Korean.

With the release of Revit 2016, Autodesk dropped support for 32-bit Windows.

The Revit workspace allows users to manipulate entire buildings or assemblies (in the design environment) or individual 3D shapes (in the family editor environment). The modeling tools can be used with pre-built solids or imported geometric models. However, Revit is not a NURBS modeling tool and you cannot manipulate the individual polygons of an object, except for a few specific object types such as roofs, slabs, and terrain, or in a solid modeling environment.

Revit contains object categories (“families” in Revit terminology). They fall into three groups:

-families of systems, such as walls, floors, roofs, ceilings, main surfaces, and even custom furniture.

-Loadable families/components built from primitives (extrusions, moldings, etc.) and projected and loaded into the project for use

-In-place families created in-place as part of the project using the same toolset as loadable components

An experienced user can create realistic and accurate families, from furniture to lighting fixtures, as well as importing existing templates from other programs. Revit families can be created as parametric models with dimensions and properties. This allows users to modify a specific component by changing predefined parameters such as: B. height, width or number in the case of a table.Thus, a family defines geometry controlled by parameters, any combination of parameters can be stored as a type, and each Revit instance of a type can contain other instances as well. For example, a swing door could be a family. It can have types describing different dimensions, and the actual building model contains instances of these types placed in walls, where instance-based settings can set door hardware unique to each door instance.

Although Revit ships with multiple families, the number of families is limited, so users may need to create their own families or purchase them from online stores.

Due to copyright issues in the design work, fully 3D Revit design models are rarely offered for sale.Since most designs are site specific and made to order, there is little demand for existing designs anyway. However, new Revit interns or students may want to use pre-built templates. There are multiple sources including sites like BIMGallery and GrabCad.

Starting with Revit 3.0, multiple users can work on the same building model.The workflow is similar to using a version control system in software development, allowing multiple developers to reliably collaborate on a common code base. Each Revit user works on a local copy of the project and regularly compares the work to a central repository. The new user first creates a local copy of this repository. When a user starts editing certain building elements, those elements are automatically locked so that others cannot edit them. The blocks are kept in a central archive.Objects remain locked until the “borrower” reviews their work and releases the locks. Patented technology called “worksharing”; allows Revit to minimize the set of locked elements by allowing the change propagation mechanism to update any number of elements, including unlocked elements. Revit generally avoids merge conflicts during check-in.

In previous versions of Revit, the central repository was a folder on the local network. This option is always available and suitable for co-locating project teams.Since 2013, Autodesk has also offered centralized, cloud-hosted repositories for Revit as a service.

When a user creates a building, model, or other object in Revit, they can use Revit rendering to get a more realistic view of an otherwise very schematic model. The user achieves this by using ready-made modeling tools, walls, floors, etc. or creating their own models, walls, materials, etc. Revit 2010 comes with many predefined materials, each of which can be modified as needed. the user’s desire. The user can also start with “Generic” Material. This allows the user to set the rotation, size, brightness, and intensity of textures, specular maps (aka specular maps), transparency maps, reflection maps, diagonal bounce maps, punched maps, bump maps, and also exit part of the map and just use the sliders for any ( or all (or none) of the above texture functions.

Cloud-based rendering with an experimental plugin called Project Neon, located at Autodesk Labs, is in beta and allows the user to render images through an Autodesk account instead of locally on their own computers . Revit models can also be linked directly to Autodesk 3ds Max (version 2013 and later) for more advanced rendering and animation projects, while preserving most material and object information.
