Pertaining to a system that that uses electrical voltage magnitudes or ratios to represent physical axis positions.
ANALYST  look up translate image
A person skilled in the development and definition of techniques to solve problems.
ANIMATED GIF  look up translate image
a GIF image that includes a number of frames that are played back rapidly to create an animation. Used mostly in Web applications.See also Graphics Interchange Format, World-Wide Web
ANSI  look up translate image

a technique for smoothing jagged lines on a graphics display.
APF  look up translate image
(Aruba Packet File) file format of Autodesk Showcase models
APPLET  look up translate image
a small program that generally provides a specific function, such as a calculator. Often associated with programs written in Java and downloaded over the Web.See also Java
APPLICATION PROGRAMMING INTERFACE (API)  look up translate image
the standard set of functions provided by a program, operating system, or piece of hardware. APIs are typically used to provide independence and division of labor. Two programs or systems that are integrated via an API can both be individually altered and still work together so long as both conform to the same API.
APT PROGRAMMING  look up translate image
Automatically Programmed Tools. A universal computer assisted programming system for multi-axis contouring programming. The original NC programming system, developed for AeroSpace, first used in building andmanufacturing military equipment.
ARC CLOCKWISE--G02  look up translate image
An arc generated by coordinated motion between two axes. Curvature of the arc is clockwise with respect to the part and the cartesian planes.
ARC COUNTERCLOCKWISE  look up translate image
G03-An arc generated by coordinated motion between two axes. Curvature of the arc is counter-clockwise with respect to the part and the cartesian planes.
ARCHITECTURAL DESKTOP  look up translate image
Autodesk Architectural Desktop (now AutoCAD Architecture) - architectural and civil engineering application by Autodesk, based on AutoCAD kernel and AEC objects
ARCHITECTURE, ENGINEERING, AND CONSTRUCTION (AEC)  look up translate image
a broad term for the segment of the CAD market that encompasses architecture, building, construction, structural engineering, civil engineering, mapping, and geographic information systems.
ARX  look up translate image

ASCII  look up translate image
(American Standard Code for Information Exchange) A data transmission code that has been established as an American Standard by the American Standards Association.
ASPECT RATIO  look up translate image
the ratio of width to height for a graphics display.
ASSOCIATIVITY  look up translate image
a link between two different functions or modules in a CAD system, such that when a change is made to one area, related areas are updated as well. For instance, a 3D model can be associated with drawings so that a change in the model is reflected in the drawings. Bi-directional associativity means that the updates happen both way no matter where the change was made, i.e. from function A to function B as well as function B to function A.Auxiliary Function--M Codes-A programming function used in CNC...(more)

AXIS  look up translate image
A principal direction along which the relative movements of a tool or work piece occur. Three linear axes, occurring at 90 degree angles from each other, named X, Y and Z.
AXIS INHIBIT  look up translate image
A feature of an NC unit that enables the operator to withhold command information from a machine tool slide.
AXIS INVERSION  look up translate image
The reversal of plus and minus values along an axis. Mirror imaging is used to make a left-handed part from a right-handed tool path. When axis inversion is used circular interpolation is also reversed.

standard measure of performance, typically for computing and graphics hardware.
BENCHMARK (VERB)  look up translate image
process of evaluating hardware and software to select the most appropriate product.
BETA SOFTWARE  look up translate image
though there's no formal definition, this term generally refers to a new release of software that is being tested by end users. Typically, end users do not pay for Beta releases.
