In this course, Diploma in Engineering Drawing and Computer Graphics, you will be introduced to Technical and Graphic Drawing for all modules of Engineering. You will begin with a brief explanation of the course and the fundamentals involved as well as what the content in this course is used for in general. You will be briefed on the equipment that you will need to be able to complete the course to its full capacity and participate in the examples in which there are multiple constructions and graphic drawing. You will continue by examining the basics of engineering drawing, covering drawing sheet layouts, and transitioning into dimensions which will be the main focus for the first module. You will discuss the specified dimensioning units that are of standard practice, and you will analyze the correct formats of dimensioning objects and constructions. You will evaluate the techniques used to do dimensioning using angles and discuss the special issues in reference to dimensioning. Lastly, you will compare different features of dimensions and their different acceptable level of tolerance with regards to the construction of the designed products.

The next section will begin with the fundamentals of geometric constructions, which is the basis of all technical drawing and is a foundation for all engineering. This will teach you how to illustrate shapes such as arcs and circles, to draw constructions effectively and accurately. You will analyze the methods used to bisect a line at a perpendicular angle, discover how to bisect and trisect angles without the use of measurements, segment a line into equal parts without measurements and construct multiple shapes including polygons. You will recall how to create a circle where the circumference runs through three different points as well as how to draw tangents. Finally, you will compare the multitude of tangent constructions from the common tangent to the interior and exterior tangents of multiple circle variations. All these constructions and techniques are used in all engineering sectors for very technical and meticulous designs. It is fundamental knowledge and will allow more complicated and complex designs for the future. Finally, you will be introduced to Conic Sections and the wide variety of techniques and formats needed to be followed to create accurate constructions.

The last section of the course will begin covering the basics of conic sections. Conic sections, also called conics, in geometry, are classified as any curve produced by the intersection of a plane and a right circular cone. Depending on the angle of the plane relative to the cone, the intersection can either produce a circle, an ellipse, a hyperbola, or a parabola. This module will cover all four of these intersection variants and the different methods used. The most used method is the Focus-Directrix Method, followed by the Concentric Circle, Oblong and Arcs methods. These are all used in different forms to construct the four shapes of the intersections. The lesser-known Rectangular method is also covered but is not as effective in constructing all four shapes. This section will reinforce tangents but with variants of the original techniques. The tangent constructions are of reference to new, special curves that are covered at the end of the course. This includes spirals, cycloids, and helixes. This course is of interest to any engineering or technological enthusiasts who would like to expand their knowledge on some of the most fundamental parts of engineering. So why wait?
