CAD Stands for Computer Aided Designs. CAD is a type of software which is widely used in Creation, Analysis and Modification of Design on Compter System. The Place of Traditional Paper Pencil and Drafters now has been Occupied by CAD Softwares. The Modern CAD software are relevant,Precise and faster then the old traditional drafting Techniques.CAD is also Called CADD sometimes which stands for “Computer Aided Designs and Drafting”. CAD is used to Create special effects and Animation in Movies and in industries such as Aerospace , Ship building, Architecture ,Mechanical Designs and Electronic Automation.CAD enables Engineers of various branches to draft the drawings and publish them in various formats.
TYPES of CAD SOftwares.
There are Many CAD Softwares available in Market such as AutoDesk AutoCAD, Albire Design , Revit, 3d Max, AutoDesk Inventor etc. Each CAD software has its separate method to create Drawings. Some low end softwares offers simple two dimensional(2D) Designs and rest others performs advance activities like three Dimensional Modeling and 2D wireframes. Wireframe is the extended version of 2D CAD designs. Every drawing created using CAD software has a definite dimensions and properties . A CAD drawing does not shows only a solid object but also express its Physical properties like area, volume, density,color and methods through which the object to be created.
(i.)2D AutoCAD Designs : Two Dimensional CAD Designs are simple flat designs which shows only two dimensions of an object.
(ii.)3D CAD Designs: Three Dimensional CAD Designs are complex designs as compared to the two dimensional designs. These type of Designs shows the all dimensions of an object from various angles.There are various methods to create 3D object like wireframe model, Surface model and Solid objects.
How CAD software works.
All of the CAD software have a different dedicated graphical user interface (GUI) in which the designers work on their computer system. An operator needs to enter the various command in the Command Bar.To create a drawing operator have to specify the position and dimensions of the object.After Finalizing the drawing user can either keep the drawing file in .dwg format(Default drawing format for CAD Drawings) or can plot it into a variety of popular formats.
