In this course, Diploma in Orthographic Projections in Engineering Graphics and Design, you will study the fundamentals of orthographic projections in engineering. By completing this course, you will have a clear understanding and ability to visualise shapes, solids and objects and draw their different technical views and projections. You will begin this course by learning what orthographic projections are, which projections to use and when to use them. Comparing projection planes and different orthographic views, such as the front view, top view, and side view will be studied in-depth. You will discuss and analyse the drawing techniques used to illustrate orthographic projects and different object views correctly. Following the drawing process, you will begin visualisation practice to explore many examples for the different orthographic projection areas. You will contrast differences in projections and form a basic understanding of the quadrant system and how points and lines are projected within this particular system. This system is the basis for orthographic projection and is fundamental to drawing objects and solids within orthographics.

Next, orthographic projection lines will be explained, and the differences between parallel, inclined, and tracing lines will be practised. Five case studies and different variations on the orthographic projection lines will be unveiled. This includes a vertical line perpendicular to both VP and HP, a line parallel to both VP and HP, and a line inclined to HP and parallel to VP, as well as variations of these. The five different examples will be studied where you will learn to identify and locate the front view and the top view of objects and understand their orientation. More examples will follow as you try to analyse different situations of these studies. Subsequently, you will be presented with projection planes and learn the differences and contrasts of auxiliary planes compared to principal planes. You will learn the different types of auxiliary planes, such as the auxiliary vertical plane, auxiliary inclined plane, and the profile plane. You will investigate how projections work on these auxiliary planes and their fundamental differences. 

In the course’s final topic, you will learn the important classifications of solids and what these classifications mean. You will study the polyhedra of solids which are the tetrahedron, hexahedron or cube, and the octahedron. You will contrast each of these and their different projection forms and how to draw them from different inclines and views. You will also tackle the solids of revolution, including the cone, oblate spheroid, prolate spheroid, cylinder, and frustum. These will all follow into the horizontal and vertical plane analysis, and you will end off by drawing examples of a multitude of solid variants. This course is a very particular and focused course on a niche area in engineering known as technical drawing, and graphic design. It is an excellent technique to visualise and conceptualise different projects and illustrate them correctly in drawing and design formats. This course is a great way to increase your knowledge of orthographic projections and gain an edge in your abilities. So why wait?
