IntelliCAD is a CAD-software programming toolkit and API published by the IntelliCAD Technology Consortium ("ITC"). IntelliCAD emulates the basic interface and functions of AutoCAD.[1] ITC IntelliCAD is not sold directly to end users but is licensed to consortium members[2] who pay fees, similar to a co-op arrangement, in exchange for permission to use IntelliCAD source code in their own products with their own end-user license agreements.[3]

IntelliCAD Technology Consortium

The IntelliCAD Technology Consortium ("ITC") is the non-profit organizational body that develops core IntelliCAD source code, toolkits, and APIs. The ITC also develops integrations with third-party technologies, such as the "ODA Platform" from the Open Design Alliance[4][5] which it uses for working with “.dwg”, Building information modeling (BIM), and DGN data formats.

The ITC is a founding member of the Open Design Alliance.[6] The ITC office base is in Portland, Oregon, USA.

IntelliCAD Functionality

IntelliCAD is compatible with .dwg and has a set of commands similar to AutoCAD by Autodesk. IntelliCAD is also compatible with DGN and has a set of commands similar to MicroStation by Bentley Systems.

Included in IntelliCAD functionality:[7][8][9]

  • Read and write binary .dwg and DGN files using technology from the Open Design Alliance.
  • Work with BIM files and data, and AEC entities.
  • Familiar command line and user interface for creating and editing CAD drawings.
  • Complex linetypes, multiline text, lightweight polylines, audit and recover, and blocks.
  • File support for customizations (.CUI), menus (.MNU), scripts (.SCR) (AutoLISP macro language), hatches, fonts including TrueType fonts, raster images, digital signatures.
  • Development APIs, such as LISP, COM, Visual Basic, and SDS (IntelliCAD's C/C++ Programming API similar to ADS) that allow developers to create custom CAD applications.

In addition to Microsoft Windows desktop versions, IntelliCAD Mobile Viewer is also available.[10]

History

Early 1990s "IntelliCADD" began as an independent AM/FM/GIS (Automated Mapping/Facilities Management/Geographic Information System) software firm in La Mesa, CA, USA. One of its products, AutoCAD Data Extension, allowed multiple users to access the same AutoCAD drawing, or have a single drawing point to entities stored in other drawings.[11] Softdesk, the then-largest third-party product developer for Autodesk, acquired this company in 1994 and used the know-how to secretly develop an AutoCAD clone.[12][13] Autodesk had recently entered into direct competition with Cyco Software (another third-party Autodesk partner), and Softdesk was concerned that the same could happen to them. The AutoCAD-clone project was kept semi-secret under the project name "Phoenix".

1996-1998 In December 1996 Autodesk announced that it would instead buy Softdesk outright for $90 million in common stock. A complaint regarding the inclusive sale of IntelliCADD was filed with the US Federal Trade Commission ("FTC"). According to FTC Docket No. C-3756:

In approximately June 1996, Softdesk determined that it no longer had the financial ability to support continued development and marketing of the IntelliCADD product. The head of the team that had developed the product proposed to purchase the technology and formed Boomerang Technology, Inc. ("Boomerang") for the purpose of acquiring the product, completing its development, and bringing the product to market. Boomerang negotiated with Softdesk for the purchase of the IntelliCADD product and exchanged draft purchase agreements with Softdesk. Softdesk, however, terminated those negotiations at around the time that Autodesk agreed to acquire Softdesk. Softdesk representatives previously told Boomerang that Softdesk would sell the IntelliCADD product to Boomerang if Softdesk were purchased by someone other than Autodesk, but would not sell it to Boomerang if Softdesk were purchased by Autodesk...
After being advised by Commission staff that Autodesk's acquisition of Softdesk raised competitive concerns in the market for personal computer-based CAD engines, Softdesk resumed negotiations with Boomerang and divested and sold all of its rights in the IntelliCADD product to Boomerang pursuant to a Technology Transfer Agreement dated February 21, 1997. On that same date, Boomerang assigned and sold all of its rights to the IntelliCADD product to Visio Corporation.

By late 1996 a formal search for new venture capital was underway. Marketing director Robert Drummer was referred to John Forbes at Visio Corporation[14] and "gave him the pitch". Further according to his own first-hand account,[15] "He (John Forbes) called back a few hours later and said that he along with Jeremy Jaech and Ted Johnson would be chartering a plane that day and would be down to take a look at a demo. They arrived in San Diego that evening." A core team of nine Softdesk/IntelliCADD developers soon moved to become employees of Visio. In March 1997 the FTC forbade "Autodesk or Softdesk from re-acquiring the IntelliCADD product or any entity that owns or controls it, without prior notice to the Commission for a 10 year period".[16][17] The FTC granted Visio leave to acquire Boomerang completely for $6.7 million in the same ruling that prevented Autodesk from doing so (above).[18] IntelliCAD's original architect, Mike Bailey, turned and left Visio before the first release. Nevertheless, after several years of background development, "Visio IntelliCAD" (one 'D' for the product, two for name of the original company) was finally released for the first time to the public in 1998[19] with a very low price compared to AutoCAD. Twelve thousand licenses of IntelliCAD were sold in the first three months before new concerns over software stability emerged.

Visio's IntelliCAD 98 sold about 30,000 copies—far less than some expected. IntelliCAD development seemed to need more resources than Visio could grant it.[20] At this point, Visio "granted a royalty- free, perpetual license for the IntelliCAD[21] (2000 version) source code to The IntelliCAD Technology Consortium".[22][23]

1999 On September 15, 1999 Microsoft announced that it would acquire Visio Corporation (completed in January 2000)—a deal that evidently included Visio's IntelliCAD 98.[24] A new IntelliCAD 2000 source code branch, however, continued independent development under the new ITC.[25]

Early 2000s IntelliCAD 3 (IntelliCAD 2001) introduced complex linetypes, XREF clipping and IntelliCAD's first display and printing of ACIS 3D solids on May 22, 2001.[26] IntelliCAD 4 released with full ACIS 3D solid modelling in 2003. IntelliCAD 5 added workspaces with tabs and DWF file support in October 2004. ITC announced a new partnership with SolidWorks,[27] which added tabbed workspaces and DWF support.[28]

Mid 2000s IntelliCAD 6 added True Color color support (16 million colors), ADeko Raster raster image support tool, previewing thumbnails while viewing drawing files, drawing and viewing elements, and attaching WAV files as audio notes in November 2005.

Late 2000s During the 2008 ITC meeting in Athens, Greece, the first test release of IntelliCAD 7 was announced with a complete replacement of the old ITC internal database and the old "SDS" API with newer DWGdirect and DRX APIs from the ODA.[29] In 2009, about 50 ITC members globally shared in IntelliCAD development.[30] Work continued on IntelliCAD 7 while simultaneously releasing IntelliCAD 6.1 through 6.6 over the next several years.

2011 The complete replacement of the old ITC internal database was released as IntelliCAD 7 in June of 2011.[31]

2014 IntelliCAD 8 was released on June 13, 2014 for 64-bit and 32-bit versions and allowed opening, saving and creating *.dwg files of the 2014 file format. New features included layer states, search layer filters, layer transparency and window freezing, custom menu *.cui files, quick selection, 3D orbits, additional mesh capabilities, Collada (.dae) file import, MrSID MG4 compressed raster image support and more. IntelliCAD 8.0 included Teigha® Open Design Alliance (ODA) version 3.9.1 and VBA 7.1 support. The source code for advanced rendering and image processing components was made available to all ITC members.[32]

2017 At the 2017 conference in Aukland, New Zealand, IntelliCAD as a native .dgn file editor was announced.[33] IntelliCAD 8.4 was released in July 2017 and included the ability to attach IFC files as underlays.[34]

2018 IntelliCAD 9 included native support for opening, editing and saving *.dwg 2018 file versions, incremental saving to increase performance, Mechanical entity support, tool palettes, and issues related to running IntelliCAD on Fall Creators 2017 Microsoft® Windows® 10 were also fixed. IntelliCAD 9 also included the ability to work with data from .rvt/.rfa files (Autodesk Revit files) and import IFC files as architectural entities. Released in June 2018. [35]

2020 IntelliCAD 10 included import of Wavefront Technologies Object (.obj) files, import and export of Stereolithography (.stl) files, dynamic input, migrate user interface customizations, and clickable keywords. Released in July 2020. [36]
