Engineering Drawing – Figure Construction Tips and Tricks [Multimedia]

Definition and construction tips for different figures for Engineering Drawing I for Computer, Civil, Mechanical, Electronics and Communication, Electrical and B. Arch board Exam of Institute of Engineering (IoE). The solutions of Engineering Drawing I and II is available on IOE Engineering Drawing Solution First & Second post.

1. Drawing Cycloid

A cycloid is a curve generated by a point on the circumference of the circle as the circle rolls along a straight line without slipping. The moving circle is called the “Generating circle” and the straight line is called the “Directing line” or the “Base line”. The point on the Generating circle which generates the curve is called the “Generating point” [download power point presentation]

2. Drawing Ellipse

An ellipse is a smooth closed curve which is symmetric about its horizontal and vertical axes. The distance between antipodal points on the ellipse, or pairs of points whose midpoint is at the center of the ellipse, is maximum along the major axis or transverse diameter, and a minimum along the perpendicular minor axis or conjugate diameter.[download power point presentation]

3. Drawing Helix

A helix is a curve in three-dimensional space that has the property that the tangent line at any point makes a constant angle with a fixed line called the axis. Examples of helixes are coil springs and the handrails of spiral staircases. .[download power point presentation]

4. Drawing Hexagon

A hexagon is a polygon with six edges and six vertices.The total of the internal angles of any hexagon is 720°.A regular hexagon has all sides of the same length, and all internal angles are 120 degrees & has 6 rotational symmetries .[download power point presentation]

5. Drawing Hyperbola

Hyperbola is the set of all points where the difference in the distance from two fixed points (called the foci) is constant. It is formed by the intersection of a plane and a cone. [download power point presentation]

6.Drawing Involute

Involute is a curve obtained from another given curve by attaching an imaginary taut string to the given curve and tracing its free end as it is wound onto that given curve.  [download power point presentation]

7. Drawing Octagon

Octagon is a regular polygon that has eight sides. A regular octagon is a closed figure with sides of the same length and internal angles of the same size. [download power point presentation]

8.Drawing Parabola

For a given point, called the focus, and a given line not through the focus, called the directrix, a parabola is the locus of points such that the distance to the focus equals the distance to the directrix.  [download power point presentation]

9.Drawing Pentagon

A pentagon is any five-sided polygon which may be simple or self-intersecting. The sum of the internal angles in a simple pentagon is 540° [download power point presentation]
