The basic programming language used by AutoCAD is the AutoLISP programming language, which is a variant of the Lisp programming language.

Today, AutoCAD still dominates the desktop CAD market.

AutoCAD History

The AutoCAD story begins in 1981, when engineers and designers in the San Francisco area were building tools for creating AutoCAD.

In 1981, Brian Walker was an engineer in the San Francisco area and worked with Frank Rothman, David Nelson, and Robert Stein to design a new drafting program. They called it “AutoCAD”. In 1982, after months of work, the first version of AutoCAD was released and proved to be a great success. That year, there were three types of programs on the market: 1) drawing programs for creating the drawings, 2) CAD programs for creating the drawings, and 3) CAD programs for producing the drawings. Frank Rothman and Robert Stein wanted to create a program that was more general purpose and would not just be used to create drawings. Thus, in 1982, they decided to design a CAD program. In 1983, they recruited Dave Nelson and Mike Britton to help them design the program and they started to work on AutoCAD. AutoCAD was originally named AutoDraw, but in 1984 the name was changed to AutoCAD.

Frank Rothman left AutoCAD in 1986 and went to work for Corel. Robert Stein continued to work on AutoCAD and the program was later marketed by SPS Technologies, Inc. Robert Stein later started the startup Corel.

In 1989, I had been a student in the University of California at Berkeley’s department of mathematics. My professor at that time, Dr. Jack Baker, gave me a program called the “U-Constructor” for creating 3D graphs and pictures. After he completed his project, I began working with him and developed a graphical user interface (GUI) for his program. I taught him how to use C++ and then he taught me the programming language Lisp. I worked on AutoCAD on my own after I graduated from college in 1990.

In 1990, I visited Microsoft and found that they were planning to create a new CAD program for Macintosh computers. Although I didn’t have any experience in CAD, I knew that I needed to work on CAD, so I contacted Dr. Jack Baker. Dr. Baker introduced me to Dr. Tony

AutoCAD supports import and export of GML files.

AutoLISP is an application programming interface for the Interactive Software Development Environment used to create automated forms. AutoLISP was introduced in version 1.0 and was introduced in AutoCAD LT version 4.0.

PowerLISP is a declarative text-based programming language which can be used to program the graphical user interface (GUI) of the AutoCAD LT and AutoCAD R11 applications. With PowerLISP, a developer creates custom tools with functionality and visual styles that can be shared among users. The PowerLISP Toolbox includes the i_PLIST compiler and editors, and can also be used to test and create custom extensions and macros for AutoCAD.


In AutoCAD LT 2010, VBA is no longer supported in AutoCAD. However, VBA can still be used in AutoCAD R11, along with.NET and ObjectARX for custom automation. AutoCAD LT 2009 and 2010 support only 32-bit VBA and AutoCAD R11 supports 64-bit.


AutoCAD has supported.NET automation since AutoCAD 2000. With the release of AutoCAD LT 2010,.NET Automation can be used with AutoCAD LT 2010. The.NET framework used is the.NET Framework 4.0.


ObjectARX is a COM automation library originally created by Motorola. ObjectARX provides a C++ library for creating C++ plugins. ObjectARX is the base for:
products extending AutoCAD functionality to specific fields creating products such as AutoCAD Architecture, AutoCAD Electrical, AutoCAD Civil 3D third-party AutoCAD-based application, Pro/ENGINEER, SimWorks, software for the Autodesk Pipeline.

AutoLISP was introduced in AutoCAD version 2.5 and was introduced in AutoCAD LT version 4.0. PowerLISP was introduced in AutoCAD version 2002 and was introduced in AutoCAD LT version 2002. The latest release of ObjectARX was AutoCAD 2010. Autodesk discontinued support for VBA in AutoCAD LT version 2011 and discontinued support for PowerLISP in Auto

The present invention relates to magnetic bearings. More particularly, the present invention relates to magnetic bearings that can provide an accurate axial magnetic force over a wide range of conditions and perform without mechanical contact.
As computer memories and other computer components become smaller and faster, it is necessary to build high-speed computing systems using ever smaller computer components. Conventional bearings may not be suitable for these high-speed, small-sized computer components because the mechanical contact of conventional bearings would cause frequent component failures. Magnetic bearings that do not contact one another and do not include mechanical parts are required to be smaller, lighter, and more accurate in order to operate in the high-speed, small-sized environments.
In conventional magnetic bearings, a force that works against gravity is provided by an induced magnetic flux. The generated flux is generally designed to provide maximum vertical force at the center of the load-bearing surface. Because the force at the load-bearing surface is proportional to the distance to the center of the load-bearing surface, the force provided by conventional magnetic bearings is not accurate over a wide range of conditions.
In addition, conventional magnetic bearings require a large opening at the top of the bearing that is used to limit the vertical component of the magnetic
