Reflex was a 3D building design software application developed in the mid 1980s and - along with its predecessor Sonata - is now regarded as a forerunner to today's building information modelling applications. [1] [2] [3] [4]
The application was developed by two former GMW Computers employees who had been involved with Sonata. After Sonata had "disappeared in a mysterious, corporate black hole, somewhere in eastern Canada in 1992," [5] Jonathan Ingram and colleague Gerard Gartside then went on to develop Reflex, bought for $30 million by Parametric Technology Corporation (PTC) in July 1996. [5] [6]
PTC had identified the architecture, engineering and construction market as a target for its parametric modelling solutions, and bought Reflex to expand into the sector. However, the fit between Reflex and PTC's existing solutions was poor, and PTC's Pro/Reflex gained little market traction; PTC then sold the product to another US company, The Beck Group, in 1997, [7] [lower-alpha 1] where it formed the kernel of a parametric estimating package called DESTINI. [9] [10]
Around the same time, several people from PTC set up a new company, Charles River Software (renamed Revit Technology Corporation in 2000, later (2002) bought by Autodesk). [7] [9] Leonid Raiz and Irwin Jungreis obtained from PTC a non-exclusive, source code development license for Reflex as part of their severance package. In the words of Jerry Laiserin: "While Autodesk Revit may not contain genomic snippets of Reflex code, Revit clearly is spiritual heir to a lineage of BIM 'begats' — RUCAPS begat Sonata, Sonata begat Reflex, and Reflex begat Revit." [11] [ unreliable source? ]
In a 2017 letter to AEC Magazine, Jungreis said:
However, Ingram, in his 2020 book Understanding BIM: The Past, Present and Future, shows much of the functionality of Reflex is duplicated in Revit. [13] A 2022 account of the history of BIM by Kasper Miller asserts: "Reflex and Revit shared a myriad of features — so much so that it is fairly clear where the Revit team found much of its inspiration". [14]
Computer-Aided Design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. Designs made through CAD software are helpful in protecting products and inventions when used in patent applications. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The terms computer-aided drafting (CAD) and computer-aided design and drafting (CADD) are also used.
Building information modeling (BIM) is a process involving the generation and management of digital representations of the physical and functional characteristics of places. BIM is supported by various tools, technologies and contracts. Building information models (BIMs) are computer files which can be extracted, exchanged or networked to support decision-making regarding a built asset. BIM software is used by individuals, businesses and government agencies who plan, design, construct, operate and maintain buildings and diverse physical infrastructures, such as water, refuse, electricity, gas, communication utilities, roads, railways, bridges, ports and tunnels.
ArchiCAD is an architectural BIM CAD software for Mac and Windows developed by the Hungarian company Graphisoft. ArchiCAD offers computer aided solutions for handling all common aspects of aesthetics and engineering during the whole design process of the built environment—buildings, interiors, urban areas, etc.
Graphisoft SE is a European multinational corporation that designs software, and is headquartered in Budapest, Hungary. As a subsidiary of Nemetschek, Graphisoft develops Building Information Modeling software products for architects, interior designers and planners. Graphisoft has subsidiaries in Germany, United States, United Kingdom, Spain, Japan and a representative office in Singapore. The company's flagship product is Archicad — an architectural design software developed since 1984 for Windows and Mac platforms.
Autodesk Revit is a building information modelling software for architects, landscape architects, structural engineers, 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 and structure and its components in 3D, annotate the model with 2D drafting elements, and access building information from the building model's database. Revit is 4D building information modeling application capable with tools to plan and track various stages in the building's lifecycle, from concept to construction and later maintenance and/or demolition.
Navisworks is a 3D design review package for Microsoft Windows.
Open Design Alliance is a nonprofit organization creating software development kits (SDKs) for engineering applications. ODA offers interoperability tools for CAD, BIM, and Mechanical industries including .dwg, .dxf, .dgn, Autodesk Revit, Autodesk Navisworks, and .ifc files and additional tools for visualization, web development, 3D PDF publishing and modeling.
RUCAPS was a computer aided design (CAD) system for architects, first developed during the 1970s and 1980s, and today credited as a forerunner of Building Information Modelling (BIM). It ran on minicomputers from Prime Computer and Digital Equipment Corporation (DEC).
ProjectWise is a suite of engineering project collaboration software from Bentley Systems designed for the architecture, engineering, construction, and owners/operator (AECO) industries. It helps project teams design, manage, review, share, and distribute engineering project content all within a single connected data environment (CDE). ProjectWise is a file and vendor agnostic solution capable of managing any type of CAD, BIM, geospatial and project data. All well, direct CAD integration is available for Bentley applications and other vendors and software titles including Autodesk & Microsoft Office.
GMW Architects was an architectural practice based in the United Kingdom. In August 2015, the firm was taken over by another business, Scott Brownrigg, "as part of plans to move into the airport sector."
Tekla Structures is a building information modeling software able to model structures that incorporate different kinds of building materials, including steel, concrete, timber and glass.
