IntelliCAD is a CAD-software programming toolkit
and API published by the IntelliCAD Technology Consortium (“ITC”). IntelliCAD aims (at some levels) to emulate
the basic interface and functions of AutoCAD. Unlike typical CAD programs, ITC IntelliCAD
is not sold directly to end users. ITC IntelliCAD is exclusively licensed to
Consortium members who pay fees in exchange for permission and guidance to include IntelliCAD
technology in final OEM “IntelliCAD” (and other) products with their own end user license
agreements. The ITC has nearly 50 members.==IntelliCAD Technology Consortium==
The IntelliCAD Technology Consortium (“ITC”) is the non-profit organizational body of developers
maintaining all vanilla-stock IntelliCAD source code toolkits and APIs for their CAD interface. The ITC also develops several advanced integrations
with third-party technologies. These third-party technologies include the
DWGdirect library (now called “Teigha for .dwg files”) from the Open Design Alliance,
which reads and writes the “.dwg” data format, and the ACIS 3D modeling kernel from
Spatial Technology. The ITC office base is in Portland, Oregon,
USA.==IntelliCAD Functionality==
Modern IntelliCAD toolkits not only provide partial compatibility with .dwg, but also
has a set of commands similar to AutoCAD by Autodesk, Inc. Similarly, IntelliCAD provides several calling
convention routines, or APIs, such as LISP, COM, Visual Basic, and SDS (IntelliCAD’s C/C++
Programming API) that allow users the ability to create complex custom CAD applications.One
focus of ITC development is improving compatibility between IntelliCAD and AutoCAD:
Read and write binary .dwg file format using technology from the Open Design Alliance
AutoCAD-like command line, menu (.MNU) and script (.SCR) files (AutoLISP macro language),
hatches, fonts and true type fonts. new: developing method DRX, comparable to
AutoCAD’s ARX.Toolkit features also include support for complex linetypes, multiline text,
lightweight polyline, draworder, audit & recover, ADS support in most applications and raster
image tools.==History==
“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. 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. 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”. 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 and “gave him the pitch”. Further according to his own first-hand account,
“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”. The FTC granted Visio leave to acquire Boomerang
completely for $6.7 million in the same ruling that prevented Autodesk from doing so (above). 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 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. At this point, Visio “granted a royalty- free,
perpetual license for the IntelliCAD (2000 version) source code to The IntelliCAD Technology
Consortium”.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. A new IntelliCAD 2000 source code branch,
however, continued independent development under the new ITC.IntelliCAD 3 (IntelliCAD
2001) introduced complex linetypes, XREF clipping and IntelliCAD’s first display and printing
of ACIS 3D solids on May 22, 2001. IntelliCAD 4 followed with full ACIS 3D solid
modelling. In October 2004, the ITC announced IntelliCAD
5, which added tabbed workspaces and DWF support. The ITC also announced a new partnership with
SolidWorks. On October 29, 2008 the first test release
of the new IntelliCAD version 7 was announced at the annual ITC meeting held in Athens,
Greece. Among the features is complete replacement
of the old ITC internal entity database and old “SDS” API with newer DWGdirect and DRX
APIs from the ODA. As of 2009, about 50 ITC members globally
shared in IntelliCAD development.==See also==
