Basics Of AutoCAD
AutoCAD is a commercial computer-aided design and drafting software application. Developed and marketed by Autodesk, AutoCAD was first released in December 1982 as a desktop app running on microcomputers with internal graphics controllers.
Computer-aided design (CAD) is the use of computers to aid in the creation, modification, analysis, or optimization of a design. The CAD 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. CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CAD (for Computer-Aided Design and Drafting) is also used
CAD is an important industrial art extensively used in many applications, including automotive, and aerospace industries, industrial and architectural design prosthetics, and many more. CAD is also widely used to produce computer animation for special effects in movies, advertising and technical manuals, often called DCC digital content creation.
Tools used in Auto CAD:
LINE: You can invoke the LINE command by choosing the LINE tool from the Draw panel or you can also invoke the LINE tool by entering LINE or L at the Command Prompt. You will have to specify the starting point of the line by clicking mouse then you will be prompted to specify the second point. You can terminate the LINE command by pressing ENTER, ESC or SPACEBAR.
Circle: A circle is drawn by using the CIRCLE command. You can draw a circle by using six different tools by specifying centre and radius, by specifying centre and diameter, by specifying two diametrical ends, by specifying three points on a circle, tangent to two objects, tangent to three objects.
2) Circle: A circle is drawn by using the CIRCLE command. You can draw a circle by using six different tools by specifying centre and radius, by specifying centre and diameter, by specifying two diametrical ends, by specifying three points on a circle, tangent to two objects, tangent to three objects.
3) Rectangle: You can draw rectangles by specifying two opposite corners of the rectangle, by specifying the area and the size of one of the sides or by specifying the dimensions of the rectangle. 4) Polyline: Polylines means many lines. To draw a polyline, you need to invoke the PLINE command. After invoking the PLINE command and specifying the start point, the following prompt is displayed
- Electronic medium
- Editing, copying, pasting, cutting, etc. are easy
- Safe time by better editing
- The sheet will be stretchable, shrinkable without using the basic characteristics of the entities (items)
- Create multiple layers
- Sheet set (paper/ model)
Properties of an entity (size, area, colour, material, line type, length, etc.)
- The file size is large
- Version program – the latest version is not supported in lower version
