When a curve is generated by cutting out a conic in such a way that the section plane is parallel to one of its generators of the conic, it is called a Parabola or Parabolic Curve . Use of Parabola or Parabolic Curves Practically, in engineering drawing, the Parabolic curves are used to draw arches , bridges , sound reflectors , light reflectors , etc. Thus, it has a huge application in architectural drawing and civil engineering drawing. Methods of construction of a Parabola (1) Eccentricity Method or General Method or Common Method It’s similar to drawing an ellipse in the Eccentricity method. Taking that same assumption into account! Draw a Parabola, where the distance between the directrix to focus is 50 mm. As we know, the eccent
