What is AutoCAD?

• CADD: Computer Aided Design and Drafting.

• Developer: Autodesk

• Autodesk is an American multinational software corporation that makes software services for the architecture, engineering, construction, manufacturing, media, education, and entertainment industries.

• AutoCAD is a commercial computer-aided design and drafting software application.

• AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.

• Operating system:Windows, macOS, iOS, Android


• AutoCAD (Computer-Aided Designs) is used to create 2D/3D models in architecture, construction, and manufacturing industries. AutoCAD allows designers to prepare blueprints and other plans through export, import, and publishing features. The ability to create both 2D and 3D designs from drafting to detailing aids in easier product development and integration.

• Civil 3D is a civil engineering design and documentation solution that supports Building Information Modeling workflows. It is used for designing, drafting and documentation, analysis, defining workflows, surveying and mapping of civil projects.

Que.19 How many units are available in AutoCAD?

a) 4

b) 5

c) 6

d) 7 •Architectural units are based in feet and inches and use fractions to represent partial inches: for example, 12′3 1/2″. The base unit is the inch unless otherwise specified, so if you enter a number like 147.5, then AutoCAD will understand it to be 12′3 1/2″.•Decimal units are unitless — that is, they’re not based on any particular real-world unit. With decimal units, each unit in the drawing could represent an inch, a millimeter, a parsec, a furlong, a fathom, a cubit (if you’re into building arks in case that rainy day should come), or any other unit of measure you deem suitable, from Danish alens to the Swiss zoll. An example would be 15.5.•Engineering units are based in feet and inches and use decimals to represent partial inches: for example, 12′3.5″.•Fractional units, like decimal units, are unitless and show values as fractions rather than decimal numbers: for example 15 1/2.•Scientific units, also unitless and show values as exponents, are used for drawing really tiny or really large things. If you design molecules or galaxies, this is the unit type for you. Examples would be 15.5E+06 (which is 15,500,000) and 15.5E–06 (which is 0.0000155). Civil Engineering by Sandeep Jyani
