Hand-Drafting vs. AutoCAD Over the years, there has been little technological advancement in architecture and interior design methods of creating drafted plans. The most significant improvement has been the development of computer aided drafting and design, or CADD. There are many notable advantages and disadvantages when comparing the use of hand-drafting and CADD drafting for creating completed design plans. When hand-drafting, speed is a time consuming issue. Drafting by hand requires a great deal of time, even for skilled drafters. Each line in the drawing must be extremely accurate. Creating each line with this kind of accuracy takes time because the drafter must measure each line using a drafting scale to the finest point of measurement. Any flaw in this area can be catastrophic to the completed project. Every letter and dimension placed in the plan must be legible, and appropriately placed so that every user of the document can refer to their particular section of the project. AutoCAD, a popular CADD computer software, has almost eliminated many of the problems with speed. Using a few simple mouse-clicks or commands, lines that are no longer needed can be easily erased. Objects such as windows and doors can be copied and placed elsewhere in the drawings quickly and efficiently. Using an offset command, parallel lines used for walls and other architectural items are created automatically. There are many other commands that can greatly reduce the time it takes to draft a design plan. AutoCAD uses an automatic ruler that displays line dimensions while drawing, eliminating the need to measure and re-measure while drawing. Accuracy within a drawing is very important when creating plans. Hand-drafting leaves much room for error. If the drafter 's pencil slips by even a millimeter, the entire plan could be inaccurate. If the mistake goes unnoticed, the finished

    A CAD model can quickly display an engineer’s ideas in a realistic way. And those models can be used to generate technical drawings that can communicate the information necessary to make the idea a reality. In order to generate a 3D model, designs must start with sketches that are generated within the CAD program. These computer generated sketches will appear resemble hand drawn sketches in geometry (the combination of points, lines, and shapes), but have big advantages over hand drawn sketches. One important difference between a freehand sketch and a CAD sketch is accuracy. The lines of a CAD sketch can be drawn perfectly straight, with start and end points that occur in exact locations in space. By using numeric (dimensional) constraints a line may also be given precise length, placed a specific distance from another sketch feature, or constrained to be oriented at a specific angle from another straight line. By applying geometric constraints a line can be made perfectly horizontal or vertical. If more than one line is being sketched, they can be made perfectly parallel or perpendicular, collinear, or equal in length. Lines can be constrained to be tangent to circles or arcs, and two circles can be constrained to be concentric. In order to precisely model a part, the designer must be able to use dimensional and geometric constraints within the CAD program.…

    Attention to detail is what separates a good digitizer from the rest. In order to be a good, or excellent embroidery digitizer requires exceptional attention to detail and knowing what can be taken out or left in a design based on the size of the finished embroidery. The best digitizers are able to sit down in front of almost any design and in his/her mind see the design running on the sewing machine. Once this level of expertise is achieved, it is a simple task to make any sewing machine perform at the highest level.…

    In the world of construction, material, labor, equipment, time and money are some of the most important factors. A speedy well planned site could decrease the construction cost drastically. Up until 1971, there was no way to use a computer and all site drawings had to be done in hand. This was very time consuming and would usually delay the rest of the construction process. During that year, a program was developed, CORELAP was one of the first site layout applications for the computer but still had its faults. Other tools for the computer were designed but most had major faults and none gained wide acceptance by the civil engineering industry. But by 1987, AutoCAD was developed and sold to computers everywhere. (Sadeghpour, Moseli & Alkass, 2006)…
