There are Two main Drafting Methods practiced in the World Today. The First which is more prominent is developed with computer Software called CAD or Computer Aided Design.
This Software allows 3D objects to be created with a series of lines, circles, and arcs combined with Three Dimensional(3D) Commands to allow the Custom 3D Design to be Developed with a large variety of complex designs.
The Second way and the one less practiced in today’s world is to use a Drafting Table and to design the Model Freehand with the use of tools like Technical pencils, Rulers, T-Squares and the All Mighty Compass.
Blueprints were originally drawn on drafting boards and drafting tables, but are now done with the use of CAD or Computer Aided Drafting. Now a day these CAD Draftsmen take 2D drawings or 2d Blueprints and transfrom them into 3D Models with the use of CAD Software. This process is known as CAD Coversion, or Paper To CAD.
The old basic Drafting procedure is to place a piece of paper or other material on a smooth surface with a right angle corners and straight sides-typically a drafting table. A sliding straightedge known as a T-square is then placed on one of the sides allowing it to be slid across the side of the table and over the surface of the paper. Parallel lines can be drawn simply by moving the T-square and running a pencil or technical pencil along the T-squares edge. Drafters also need to draw curves and circles with different radius.The tool that is primarily used is the compass.Another tool used to draw curves is called a Spline.A Spline is a rubber coated articulated metal that can be manually bent to most curves.
Paper To CAD
Paper To CAD otherwise known as CAD Conversion is done by a CAD Designer like eLine Design. As long as all the design information is included in a 2D Drawing like the length, width, and height. A CAD Draftsmen can develop a 3D Model with 2D Blueprints. Another name for this process is PDF To DWG, and 2D to 3D
Sketches are usually drawn several times before the Final process begins with this type of Drafting Method. A Sketch is a quickly executed freehand drawing that is not intended as a finished work. In most cases a sketch is a quick way to record an idea for later use. Architect’s use sketches primarily to serve as a way to try out different ideas and establish a composition before undertaking a more finished work. Architectural sketches for example are a kind of diagram. These sketches are used by Architects as a means of communication in aiding Design collaboration. Sketches help Architects to abstract attributes of hypothetical provisional Design solutions and summarize their complex patterns, thereby enhancing the design process.
Today the basic functions of the Drafter have been accelerated through the use of Computer Aided Design systems or CAD. Computer aided design is the use of computer technology to aid in the design and particularly the drafting of a part or product, including entire buildings. It is both a visual and symbol based method of communication whose conventions are particular to a specific technical field.
