Exercise 1.8: Draw the Isometric view from the provided views (Front, Top, Right). Note: Third Angle Projection. Isometric Rule #1: Measurement can only be made on or parallel to the isometric axis. Isometric Rule #2: When drawing ellipses on normal isometric planes, the minor axis of the ellipse is perpendicular to the plane containing the ellipse. The minor axis is perpendicular to the corresponding normal isometric plane.

There are two points, A and B, whose elevations above datum are h4 = 1380 ft and hp = 930 ft. and whose images a and b on a vertical photograph have photo coordinates a = 2.95 in.. y = 2.32 in. z = -1.64 in., and 3 = -2.66 in. The camera focal length was 152.4 mm and the flying height above datum 7800 ft. Part A On the same photograph, an image d of a third point D appears. Its elevation is hp 1290 ft and its photo coordinates are zd=2.72 in. and yu = 3.09 in. Calculate the area, in acres, of triangle ABD Express your answer to four significant figures.
