Draw Ellipse By Directrix Focus Method How To Construct An Ellipseо Engineering drawing construction of ellipse by general or directrix focus methodwe are explaining the construction of an ellipse when eccentricity and dist. Focus directrix or eccentricity method given : the distance of focus from the directrix and eccentricity example : draw an ellipse if the distance of focus from the directrix is 70 mm and the eccentricity is 3 4. 1. draw the directrix ab and axis cc’ 2. mark f on cc’ such that cf = 70 mm. 3. divide cf into 7 equal parts and mark v at the 3. Focus directrix property of an ellipse. consider an ellipse (x 2 a 2) (y 2 b 2) = 1 . draw the lines zd and zd’ whose equations are x = a e and x = a e respectively. let p (x,y) be any two points on the ellipse. let d’ pd be parallel to the x axis. the foci are f (c,o) and f’ ( c,o). – draw an ellipse if the distance of the focus from the directrix50 mm and the eccentricity is 2 3 – draw a parabola if the distance of the focus from the directrixis 55 mm – draw a hyperbola of e = 4 3 if the distance of the focus from the directrix= 60 mm • concentric method – draw an ellipse having the major axis of 60 mm and the.
