GPIUTMD - Engineering Drawing I

Redistribution and use of the material in this page, with or without modification, are not permitted.

An engineering drawing, a type of technical drawing, is used to fully and clearly define requirements for engineered items.

Engineering drawing (the activity) produces engineering drawings (the documents). More than just the drawing of pictures, it is also a language; a graphical language that communicates ideas and information from one mind to another. Most especially, it communicates all needed information from the engineer who designed a part to the workers who will make it.

Drawings convey the following critical information:

Geometry - the shape of the object; represented as views; how the object will look when it is viewed from various angles, such as front, top, side, etc.
Multiple views and projections: Orthographic projection, Auxiliary projection, Isometric projection, Oblique projection, Perspective, Section Views, etc.
Dimensions - the size of the object is captured in accepted units.
tolerances - the allowable variations for each dimension.
Material - represents what the item is made of.
Finish - specifies the surface quality of the item, functional or cosmetic. For example, a mass-marketed product usually requires a much higher surface quality than, say, a component that goes inside industrial machinery.

This course is mainly devided to two parts. The First part is an Introduction to basics of technical drawing.

Part I - Basics of Technical Drawing

Session 01 - Introduction to Graphics Language and Three Basic Views
Session 02 - Engineering Drawing Standards, Views Connections
Session 03 - Application of Views Connection, Six Views, Drawing Methods
Session 04 - Troubleshooting Unknown Views
Session 05 - Volume Analysis
Session 06 - Plane Analysis

The second part covers the general information and rules regarding the actual technical drawings:

Part II - General Technical Drawing

Session 07 - Isometric View
Session 08 - Dimetric, Cavalier and Cabinet Views
Session 09 - Section Views
Session 10 - Section Views - Continued
Session 11 - Threads, Hex Bolts and Hex Nuts
Session 12 - Mechanical Drawings and Dimensioning
