  1. Hexagonal Prism Graphic Communication Department of Technological Education

  2. Department of Technological Education Cut Hexagonal Prism - Question • The given views show the Front Elevation and Plan of a cut hexagonal prism. • Draw the following views :- • End Elevation • Surface Development of sides • True Shape of cut

  3. Department of Technological Education Finding position of End Elevation • Project the outline of the End Elevation from the Front Elevation and the Plan.

  4. Department of Technological Education Identifying Generators • Number each of the points on each of the views. 1 2 6 3 5 4 3 /6 4 /5 /4 1 /5 2 1 /2 6 3

Join each of the points to find the cut shape on the End Elevation • Project from the cutting line on the Elevation to find the cut points on the End Elevation.

Draw a vertical generator to indicate where the Development will start, and then step out the width for the six sides. Draw generators through each of these points. Number each of the generators starting with either the highest point or the lowest point. Project each of the cut points from the Elevation onto the appropriate Development generator and draw straight lines to indicate the shape of the Development. 6 1 3 2 4 5 6

Also add a datum line to the plan. 4 Measure the vertical distances from the datum to each of the cut points. Transfer these sizes onto the True Shape. 6 5 6 1 3 2 4 5 6
