An Education In Mechanical Drafting

Drafting is a form of graphic expression so it is therefore a type of language. When applied in the engineering field, drawing or drafting is mechanical in character and is used primarily for the purpose of communicating information related to the construction of machines and structures. It is then reasonable to believe that the methods used and the standards adopted in the teaching of engineering drafting would be based on an study of the conditions found in the engineering world.

In the best engineering practice, the technical standards of drawing are high, so high in fact that they should be used as a model to use in the classroom. Examples of good draftsmanship selected from real world engineering offices would most definitely serve to furnish a model for classroom work, both in the technique and the methods of representation.

Engineering drawing demands brain power as much as it does skill with the hands. The drafter in conceiving and planning his design, visualizes their problem, making all the necessary calculations for it, and then graphically representing the results on the drafting board or CAD Program. The development of all the details of their design makes it necessary that they be a trained observer of shapes, forms, and methods.

Since new designs frequently involve modifications of old designs, in their efforts to remember old designs and create new ones, they develop what is known in the trade as a visual memory. Modern methods of instruction recognize and encourage both the physical and mental factors involved in the production of engineering drawings. It is the aim of the drafting course in technical or engineering schools to familiarize the student with the standards of technique and methods of representation found in the best commercial firms and also to develop in them the ability to visualize and reason, which should be the attributes of the commercial drafter and designer.

    I really appreciate the fact that you have this course available. I have degrees in mechanical & aerospace engineering, and we homeschool, and my 12y old son expresses a lot of talent in mechanics & mathematics, and I wanted him to be able to take some classes in drawing. I have taught him what I could thus far, but it seems like I keep going back over things that I forgot to mention, out of order, saying things like, “Oh, yeah, by the way, different line thicknesses and dash-types mean different things…” or “yeah, that’s the dimensioning tolerance symbol for runout…”, stuff that I just overlooked and forgot that he doesn’t just automatically know. So, having a well-thought-out course of study for him is what I am hoping to find here so that he and I can continue to work in our shop together and build things, and if he decides to eventually go into an engineering course of study, he is well prepared for what he’ll hit.

    It is a really good thing to see you offering your knowledge to others. My father went through drafting school 20 years ago and now is a mechanical design engineer. These jobs are becoming more important every day. Along with the drafters and engineers, the software’s are also evolving compared to what they used to. I remember going to my dads work when they were printing off the blue print plotters.
