Line: It is an entity to specify or connect two points.A line has two end points;one is start point,other is end point.These two points are specified in AutoCAD using co-ordinates namely (1,1) as start point and (10,20) as end point.(1,1) indicates the distance of the point from the origin that is (0,0) along the x-axis and y-axis respectively.
The DRAW is the first and the foremost of the menus used in AutoCAD.The DRAW menu consists of the following sub commands.
1.Line
2.Ray
3.Construction Line
4.Multi Line
5.PolyLine
6.3D polyline
7.Polygon
8.rectangle
9.Helix
10.Arc
11.Circle
12.Donut
13.Spline
14.Ellipse
15.Block
16.Table
17.Point
18.Hatch
19.Gradient
20.Boundary
21.Region
22.Wipeout
23.Revision Cloud
24.Text
The details of each of the sub commands will be discussed in the coming posts.
Auto CAD commands can be simply categorized according to geometry being drawn or constructed.We need to draw the geometry so DRAW menu is used.To modify the drawn geometry MODIFY menu is used.To give parameters to the drawn geometry DIMENSION menu is used.INSERT menu is used to import files,attach external reference files and attach images for capture.TOOLS menu is used to perform specific evaluation of the drawn data.Each MENU contains many sub-commands which will be discussed in the following posts.

The basic AutoCAD environment can divided into three divisions.
AutoCAD
AutoCAD is extensively used in manufacturing and design Industries through out the world. It forms the basic insight into design, planning and implementation of projects ranging from oil distribution through pipelines, construction and design of buildings, residential or commercial to basic manufacturing of mechanical parts produced in a machine shop. So it is relevant that a production drawing or a digital representation of the plan is mandatory before the project is implemented. Hence AutoCAD provides a way to analyze the plan layout before being executed.
The basic version of AutoCAD used is AUTOCAD2004.The latest version available from AUTODESK, which is the company that releases the software is AUTOCAD2010.
I would like to start with AUTOCAD2007 which is the widely used version as of now.
In this version both 3-Dimensional modeling of products as well as 2-dimenional drawings can be created.
But usually AutoCAD is used as a 2D drafting tool and for 3D various other high end software’s are used.
Some of the high end software’s used for 3D are SolidWorks, Pro-Engineer, Catia, SolidEdge, Autodesk Inventor, Ideas etc.
CAD or CADD refers to computer aided design and drafting used in analyzing,simulating and interpreting a product and its performance in a virtual way before it is put into manufacturing.A products life cycle is optimized using a CAD application and the performance, reliability cad be enhanced contributing towards efficient production.
Cad-biz.com is started by me with the intention of sharing my views on computer aided design and its importance in the design and manufacturing of products pertaining to different fields of application from aerospace to medical technology.It is a quick way of assessing the efficacy and performance of the product designed.
My intention also is to provide my services as a +cad+ engineer in the form of freelance projects.
