DXF
AutoCAD DXF (Drawing Interchange Format, or Drawing Exchange Format) is a computer-aided design (CAD) data file format developed by Autodesk to enable CAD data exchange and interoperability between AutoCAD on different computing platforms. History DXF was introduced in December 1982 as part of AutoCAD 1.0, and was intended to provide an exact representation of the data in the AutoCAD native file format, DWG (Drawing). For many years, Autodesk did not publish specifications, making correct creation of DXF files difficult. Autodesk now publishes the incomplete DXF specifications online. Compatibility Versions of AutoCAD from Release 10 (October 1988) and up support both American Standard Code for Information Interchange (ASCII) and binary forms of DXF. Earlier versions support only ASCII. As AutoCAD has become more powerful, supporting more complex object types, DXF has become less useful. Certain object types, including ACIS solids and regions, are not documented. Other ob ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LibreCAD
LibreCAD is a computer-aided design (CAD) Application software, application for 2D design. It is free and open-source software, free and open-source, and available for Unix/Linux, macOS, and Microsoft Windows operating systems. Most of the interface and handle concepts are analogous to AutoCAD, making it easier to use for users with experience in this type of commercial CAD application. History Around 2010, the QCAD, QCAD Community Edition 2.0.5 was fork (software development), forked to start the development of what is now known as LibreCAD. Originally, the GUI was based on Qt (software), Qt3 libraries. CADuntu ''CADuntu'' — was the initial ''QCAD CE'' fork project name. It was used for a short time and, after discussion with users, has been replaced by ''LibreCAD'', as to not be associated with Ubuntu and Canonical (company), Canonical Ltd. LibreCAD 1 The main feature of ''LibreCAD 1'' was porting of its graphical user interface (GUI) code to Qt (software), Qt4, so ...

CAD Data Exchange
CAD data exchange is a method of Engineering drawing, drawing data exchange used to translate between different computer-aided design (Computer-aided design, CAD) authoring systems or between CAD and other downstream CAx systems. Many companies use different CAD systems and exchange CAD data file format with suppliers, customers, and subcontractors. Such formats are often proprietary. Transfer of data is necessary so that, for example, one organization can be developing a CAD model, while another performs analysis work on the same model; at the same time a third organization is responsible for manufacturing the product.Xu, X. (2009). ''Integrating advanced computer-aided design, manufacturing, and numerical control: Principles and implementations''. Hershey, PA: Information Science Reference. Since the 1980s, a Computer-aided technologies, range of different CAD technologies have emerged. They differ in their application aims, user interfaces, performance levels, and in data s ...

File Format
A file format is a Computer standard, standard way that information is encoded for storage in a computer file. It specifies how bits are used to encode information in a digital storage medium. File formats may be either proprietary format, proprietary or open format, open. Some file formats are designed for very particular types of data: Portable Network Graphics, PNG files, for example, store Raster graphics, bitmapped Graphics file format, images using lossless data compression. Other file formats, however, are designed for storage of several different types of data: the Ogg format can act as a container format (digital), container for different types of multimedia including any combination of sound, audio and video, with or without text (such as subtitles), and metadata. A text file can contain any stream of characters, including possible control characters, and is encoded in one of various Character encoding, character encoding schemes. Some file formats, such as HTML, sca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QCAD

Design Web Format
Design Web Format (DWF) is a file format developed by Autodesk for the efficient distribution and communication of rich design data to anyone who needs to view, review, or print design files. Because DWF files are highly compressed, they are smaller and faster to transmit than design files, without the overhead associated with complex CAD drawings (or the management of external links and dependencies). With DWF functionality, publishers of design data can limit the specific design data and plot styles to only what they want recipients to see and can publish multisheet drawing sets from multiple AutoCAD drawings in a single DWF file. They can also publish 3D models from most Autodesk design applications. DWF files are not a replacement for native CAD formats such as AutoCAD drawings ( DWG). The sole purpose of DWF is to allow designers, engineers, project managers, and their colleagues to communicate design information and design content to anyone needing to view, review, or pri ...

Open File Format
An open file format is a file format for storing digital data, defined by an openly published specification usually maintained by a standards organization, and which can be used and implemented by anyone. An open file format is licensed with an open license. For example, an open format can be implemented by both proprietary and free and open-source software, using the typical software licenses used by each. In contrast to open file formats, closed file formats are considered trade secrets. Depending on the definition, the specification of an open format may require a fee to access or, very rarely, contain other restrictions. The range of meanings is similar to that of the term open standard. Specific definitions UK government In 2012 the UK Government created the policy Open Standards Principles, stating that the Open Standards Principles apply to every aspect of government IT and that Government technology must remain open to everyone.

Computer-aided Design
Computer-aided design (CAD) is the use of computers (or ) 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 help protect 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. Its use in designing electronic systems is known as ''electronic design automation'' (''EDA''). In mechanical design it is known as ''mechanical design automation'' (''MDA''), which includes the process of creating a technical drawing with the use of computer software. CAD software for mechanical design uses either vector-based graphics to depict t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1982 Introductions
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
