The optional 6 kB "Screenware Pak II" (in 8 kB of ROM) was a superset of Pak I, adding circle, line and polygon drawing routines, flood fill and a variety of other features. [3] Pak II also added a "split screen" function, allowing a portion of the screen to be placed in graphics mode and the rest in text mode, which some considered a necessity ...
The 4th Generation of the MEDUSA 2D and 3D CAD product family was released by the company CAD Schroer in the summer of 2004. Various software modules and packages have been developed, with MEDUSA4 DRAFTING PLUS, a 2D CAD program with all the standard 2D design functionality and BACIS1 and BACIS2 customisation tools as the base product.
IntelliCAD is a CAD editor and development platform with an API published by the IntelliCAD Technology Consortium (ITC) through shared development. IntelliCAD emulates the basic interface and functions of AutoCAD, however, it is particularly able to incorporate and interchange freely between a wide variety of file types (i.e., .dwg, BIM, TIFF, etc.).
Today, the mechanics of the drafting task have largely been automated and accelerated through the use of computer-aided design systems (CAD). There are two types of computer-aided design systems used for the production of technical drawings: two dimensions ("2D") and three dimensions ("3D"). An example of a drawing drafted in AutoCAD
An example of a multiview orthographic drawing from a US Patent (1913), showing two views of the same object. Third angle projection is used. In third-angle projection , the object is conceptually located in quadrant III, i.e. it is positioned below and behind the viewing planes, the planes are transparent , and each view is pulled onto the ...
A 2D CAD drawing A 3D CAD model Computer-aided design ( CAD ) is the use of computers (or workstations ) to aid in the creation, modification, analysis, or optimization of a design . [ 1 ] : 3 This software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to ...
LibreCAD is a computer-aided design (CAD) application for 2D design. It is free and open-source, and available for Unix/Linux, macOS, and 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.
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
