The Art of Computer Aided Drafting (CAD) thru the Alphabet of Line
	The basic application of 2 dimensional drawing using the "alphabet of lines" is similar on how we adapt in manual drafting with the variations of line widths to highlight a major object and separate visibly the minor object. With the designation of line widths (alphabet of lines) we can easily determine in Elevations, Sections and Details the "in and out" of a wall, column or the extrude and recess of surfaces. While in floor plans, wall line is normally more thicker against hatching, dimension lines, doors and other minor elements or objects that varies the line width designations. As in AutoCAD or any CAD programs, the "alphabet of lines" is determined on the designation of layer colors which refers to each line width in plotting or printing which generally in monochrome or black & white output. This result is to understand that producing a drawing is not just simply drawn with single line width but to introduce a graphically presentable, readable construction drawing or producing an artistic black in white 2D architectural CAD presentation.

	A sample elevation drawn in AutoCAD with layer colors designated as follows:
	LAYERS	PEN WIDTH
	Red	0.1
	Yellow	0.2
	Green	0.3
	Cyan	0.4
	Blue	0.5
	Magenta	0.6
	White	0.7
	Gray	0.05
	Brown	0.05
			But a Single Line width without the application of alphabet of line can be applied similar to the above image using the shade and shadow hatch treatment.
