Construct Ellipse Engineering Graphics

The document discusses engineering graphics focusing on conic sections, specifically ellipses, parabolas, and hyperbolas, and details various methods to construct them, such as concentric circles, rectangles, and arcs of circles. It includes example problems with specific dimensions for drawing ellipses and explains the concept of eccentricity for these curves. The document outlines the relationships and properties of these geometric shapes in relation to a fixed point and line.
