CAD - Computer Aided Design

What Is CAD?
CAD stands for Computer Aided Design (and/or drafting, depending on the industry) and is computer software used to create 2D and 3D models and designs.To get more news about computer aided drawing and design, you can visit shine news official website.

CAD software is used across many different industries and occupations, and can be used to make architectural designs, building plans, floor plans, electrical schematics, mechanical drawings, technical drawings, blueprints and even the special effects in your favorite movies and TV shows.
Benefits of CAD
Prior to the advent of computer aided design, designs needed to be manually drawn using pencil and paper. Every object, line or curve needed to be drawn by hand using rulers, protractors and other drafting tools. Calculations, such as the structural load on a building component, would need to be done manually by an engineer or designer, a very time consuming - and error prone - process.

CAD software changed all of this. Designs can be created and edited in much less time, as well as saved for future use. CAD drawings are not limited to the 2D space of a piece of paper, and can be viewed from many different angles to ensure proper fit and design. Calculations are performed by the computer, making it much easier to test the viability of designs. Designs can be shared and collaborated on in real time, greatly decreasing the overall time needed to complete a drawing.

Types of CAD Drawings
There are a wide variety of uses for CAD software and the types of designs that can be made. Below are some common designs and drawings that can be made with CAD software.

Floor Plans
Floor plans are scaled diagrams that show the size, placement and shape of rooms and other objects within a structure using a top down view. Floor plans help to visualize the footprint of a building, home or other structure. Floor plans are great for laying out objects, like furniture, within a structure to ensure a proper fit.
Technical Drawings & Blueprints
A technical drawing is a detailed, scaled plan or drawing of an object. Technical drawings are used to deliver exact specifications of how something should be made. Technical drawings can include architectural, mechanical and engineering designs. Blueprints are reproductions of technical drawings, but the word blueprint is also used to describe any type of plan, such as a floor plan.
Piping & Instrumentation Diagrams
A piping & instrumentation diagram (P&ID) shows the relationships between piping, instrumentation and other system components in a physical process flow. For example, a P&ID can show the types of valves, pumps, tanks and other components within the larger system, and how they connect to, and interact with, one another.
HVAC Diagrams
Heating, ventilation, and air conditioning (HVAC) drawings provide information about the ventilation, heating and air conditioning systems within a given location. They can include the size and location of ductwork, connections to control units, as well as the relationship and connections between various components.
Site & Plot Plans
Site plans, also known as plot plans, are top down view, scaled drawings showing the proposed usage and development of a piece of land. Site plans can include the footprint of buildings, landscaping designs, walkways, parking lots, drainage and water lines, and will show the placement of all of these items relative to one another.
Electrical Schematics
Electrical schematics provide an overview of what components are included in an electrical system, and the relationship between those components. Electrical schematics typically use symbols to represent the various components and elements within an electrical system. For more granularity regarding placement of the electrical components, and how wires connect to them and each other, a wiring diagram would be more useful.
