. Canadian Shipping and Marine Engineering January-December 1918. s to K S N draw the perpendicuiar16, 16° intersecting the semicircle K S°N at 16°. Transfer this length 16, 16^to 16 16° in the sectional view for thisplane, which is X X. T T° is drawn atright angles to C T D, and its lengthtransferred to T T° in the sectional view. The distance X X° in the sectionalview is equal to the distance through Xon the line X X in the elevation. Thisdistance is not shown in the elevationview, but it is obtained by using a littlejudgment. The distance through thepo>.it 5 13 equal to 5 5° and through thepoint 3 is equal to 3 3°, so if X was mid-way between the points 3 and 5, it wouldbe equal to the mean of the two distances3 3° and 5 5°. But X is nearer to 5 than3, so it will be seen that it is not difficultto get the distance X X° for the cross-section. An even curve drawn throughthe points T° 16° 15° 5° and X, in thesection view, will define the half-sectionfor the plane X X. The sections for YY and W W areconstructed in a similar FIG. 5. DEVELOPMENT OF TEMPLETS FORSIDE SHEETS. The plane lines WW, X X and Y Yin Fig. 2 are transferred over to theirproper positions in Fig. 5. The distanceX° 15° 16° and T° in the sectional 2, is equal to the curve of the sidesheet; it is, therefore transferred overto Fig. 5, measuring from the point Xalong the line X X to the point T\ With;the three points 9, T and 10 located,, 46 MARINE ENGINEERING OF CANADA the curve may be drawn in by a flexiblebatten. The points W and Y on thiscurve are located by taking thelength of the curve 3° 11° 12° 13° and14°, Fig. 2, and measuring this along theline Y Y, Fig. 5, from the point Y tolocate Y. To locate W, the distance18° 19° and 20°, Fig. 2, is measured fromW along the line W W, Fig. 5. Fivepoints are shown to locate the curve 9W T Y and 10 and, although threepoints would be quite sufficient, the num-ber is left to the option of the three poi
