A collection of courses that shed light on the drawings used in engineering - how they are made and used, and their importance.
An engineering drawing is a type of technical drawing used to define the requirements for engineering products or components. Typically, the purpose of an engineering drawing is to clearly and accurately capture all geometric features of a product or component so that a manufacturer or engineer can produce the required item. It may also describe the process of making the item, may be used to convey engineering ideas during the design process, or may provide a record of an existing item.
Rather than being an illustration, an engineering drawing is intended to describe the size and shape of an item and may provide information regarding acceptable variations, load limits, materials and any other information that can help give a complete understanding of an item.
Drawings can be created in Oblique and Isometric as well as First and Third Projection.
It is usual for engineering drawings to include a series of projections showing different angles of the item, as well as sections, ‘exploded’ views and so on. Projections may create two dimensional or three dimensional representations of the item.
Increasingly, engineering drawings are prepared using computers that can also create files used to instruct machines how to manufacture the item.

The projections of a straight line may be drawn by joining the respective projections of its ends which are points.
This course is about the types of curves which are commonly used in engineering practice.
Types of solids, projections of solids in various positions, projection of spheres and more.
A scale is defined as the ratio of the linear dimensions of the object represented in a drawing to the actual dimensions of the same.
Practical solid geometry or descriptive geometry deals with the representation of points, lines, planes and solids on a flat surface.
Isometric drawing is a graphical representation of 3 dimensional objects which are shown in one view and where all lines are measurable.
