Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1884 edition. Excerpt: ... XXXIV. (Plate XXXVI, fig. 1)--Hexagonal Prism.--Draw the rectangular figure ABCD, beginning with AB, which, being a horizontal line parallel to your imaginary picture plane, requires no guide line. Next draw the two vertical construction lines AC, BD, taking care that they bear the right proportionate length to AB. Divide AC into two equal parts in point 1, also BD in point 2. Through points 1 and 2 draw a horizontal line, making it twice as long as the distance 1 to 2, by marking the centre O between the points 1 and 2, and setting off the distance I.E. = 1.0. and 2.F. = 2.0. Join EA, EC, FB, FD. To complete the figure, draw the converging lines from F, D, C, and E, then the horizontal distant line cd, and the lines ce and df parallel to CE and DF respectively. If the height of the-face of the figure is in right proportion to its width, AOB should be an equilateral triangle and may be tested as such. A concertina might be used for a model. You may commence this view of the figure by drawing EF. Divide it into 4 equal parts in I.O.2. Through 1 and 2 draw vertical lines AC, BD. On EO draw an equilateral triangle, and proceed as at page 27. Exergue XXXV. (fig. 2).--Commence with the vertical construction line AC and mark its centre 1. Through A draw a horizontal guide line. Hold jour pencil horizontally, so that its upper edge appears to touch point A, in-order to judge the slope of the line AB of the model, and make your line AB incline as much in regard to your guide line as the line AB of the model appeared to incline to the edge of your pencil. Find the proportion existing between the apparent length of line AB on the model with the vertical height AC, and having determined point B on your drawing, draw the vertical construction linesshow more
