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 It was used for a short time and, after discussion with users, has been replaced by ''LibreCAD'', as to not be associated with Ubuntu and Canonical (company), Canonical Ltd.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 ...

GNU General Public License
The GNU General Public Licenses (GNU GPL or simply GPL) are a series of widely used free software licenses, or ''copyleft'' licenses, that guarantee end users the freedom to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. The GPL is more restrictive than the GNU Lesser General Public License, and even more distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache. Historically, the GPL license family has been one of the most popular software licenses in the free and open-source software (FOSS) domai ...

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] [Amazon] |
QCAD
QCAD is a computer-aided design (CAD) software application for 2D design and drafting. It is available for Linux, Apple macOS, Unix and Microsoft Windows. The QCAD GUI is based on the Qt framework. Description QCAD is partly released under the GNU General Public License. Precompiled packages are available for 32-bit and 64-bit Linux platforms, Microsoft Windows OS and macOS. QCAD is developed by RibbonSoft. Development on QCAD began in October 1999, starting with code from CAM Expert. QCAD 2, designed to "make QCAD more productive, more user friendly, more flexible and increase its compatibility with other products" began development in May 2002. QCAD 3 was first released in August 2011 with an ECMAScript (JavaScript) interface as major addition. Some of the interface and concepts behind QCAD are similar to those of AutoCAD. QCAD uses the DXF file format internally and to save and import files. Support for the popular DWG file format is available as a commercial plugin b ...

AutoCAD
AutoCAD is a 2D and 3D computer-aided design (CAD) software application developed by Autodesk. It was first released in December 1982 for the CP/M and IBM PC platforms as a desktop app running on microcomputers with internal graphics controllers. Initially a DOS application, subsequent versions were later released for other platforms including Classic Mac OS (1992), Microsoft Windows (1993) and macOS (2010), iOS (2010), and Android (2011). AutoCAD is a general drafting and design application used in industry by architects, project managers, engineers, interior designers, graphic designers, city planners, and other professionals to prepare technical drawings. After discontinuing the sale of perpetual licenses in January 2016, commercial versions of AutoCAD are licensed through a term-based subscription or Autodesk Flex, a pay-as-you-go option introduced on September 24, 2021. Subscriptions to the desktop version of AutoCAD include access to the web and mobile applications ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
AutoCAD 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 file, 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 documente ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Ribbon UI
In computer interface design, a ribbon is a graphical control element in the form of a set of toolbars placed on several tabs. The typical structure of a ribbon includes large, tabbed toolbars, filled with graphical buttons and other graphical control elements, grouped by functionality. Such ribbons use tabs to expose different sets of controls, eliminating the need for numerous parallel toolbars. Contextual tabs are tabs that appear only when the user needs them. For instance, in a word processor, an image-related tab may appear when the user selects an image in a document, allowing the user to interact with that image. Use of the term "ribbon" dates back to the 1980s and was originally used as a synonym for plain toolbar. However, in 2007, Microsoft used the term to refer to its own implementation of tabbed toolbars encompassing a conglomerate of controls for Microsoft Office 2007, which Microsoft calls "The Fluent UI". Although Microsoft popularized the term with a new meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
