Computer aided drawing (CAD) has evolved immensely over the last few years. The age of free hand drawing is almost over and engineers, architects and manufactures rely on Computer aided drawing these days. This technology allows one to make multiple modifications, additions and deletions of technical elements quickly and easily.
Computer aided drawing also allows for simplified management, transfer and reproduction of the designs. One can also archive a document and would never lose a design ever. Regardless of the industry, Computer aided drawing (CAD) can create plans and other technical elements for any project.
Computer aided drawing (CAD) is less prone to mistakes and hence involves fewer poorly drawn lines. In case of freehand drawing it is hard to detect a mistake in 2D, however the 3D representation allows one to detect and correct errors quickly. The Computer aided drawing (CAD) also allows faster drawing because lines and shapes can be drawn very quickly with a few simple clicks of the mouse.
