Drafting, or otherwise known as "technical drawing," is basically architectural work. The work of each individual type of pencil, portrays a different type of line, that will eventually lead to a new type of drawing. Now, as most of us may or may not know, drafting isn't simply a plain drawing. No! Drafting requires skill, and proportional work. No measurements should be left alone, as each one has a significant meaning.

Simple Dimensions
Often, the hardest part of drafting, is adding the dimension on the drawing itself. Certain measurements can be jumbled with the rest, so you must take precautions in adding them. Dimensioning is simply taking the measurements on the instruction,and applying it to the actual object, either on the side, or somewhere else near the object.
Three Dimensional Drawings
In the course drafting, you are taught to draw in two types of styles; Two dimensional, and three dimensional. Three dimensional object project the object to look more realistic, but in drafting, the view is different. The view is still 2D, but instead of looking at the drawing from one perspective, you are looking at it from three types of view. The three main views a; the front view, the right side view and the top view. Now, you must keep in mind that these are only the three MAIN views, so there are many more. The process in drawing these three main views may seem difficult, but once you get the hang of it, it seems rather easy. First and for most, you must set up your drawing. You can do this by sketching your layout, which consists of your border lines, and some boxes on the bottom of your drawing for your name, period, scale, etc. After completing that task, you can draw the lines to fill inside of your title boxes on the bottom. They must be 1/8 an inch from the bottom of the box, and 1/8 an inch from the top of the box. There are three types of main pencils the draftsmen use. The 2H, the 4H, and the H or F. 2H's are used to Letter, and dimension your drawing. The 4H is the second to lightest type of pencil we use for drafting. We use the 4H to sketch or layout, and draw our object with, so in case we might make a mistake, we can easily erase it without making any marks. Scales, triangles, T-squares, and the drafting board are all important pieces of material drafters need to get started on a drawing. The scales aren't rulers, but similarly related to them. Instead of being two sided, they are six sided. Each side has their own specific measurement. The triangles are two different types of triangles, with different angle measurements. One of them is a 90 degrees, and two 45 degrees, while the other is 60 degrees, 30 degrees, and 90 degrees. The drafting board is merely what you use to anchor your paper down to.
When drawing drafting drawings especially, proportion should be used greatly. Whatever you think looks right, is most likely going to be wrong, simply because most drawing aren't what they seem. The shape might seem a bit off, but if you come to a problem, where you absolutely know that there is something off, then take another look at the direction on your sheet. The front view on an object should connect to the right side view, and the top view should connect to the right side view, as well. For drafting, we commonly use the motto "Draw all the lines on the paper, then use the eraser to make the drawing appear."
