Cut Hexagonal Prisms – What Are They?

This type of drawing is asked to be drawn as part of a cut, prism, pyramid, cylinder or cone. It shows the actual shape of a sloping surface. They can be quite confusing but are not as hard to produce as they look.

As there are other slides and presentations depicting how to draw cut prisms, pyramids, cylinders and cones we are not going to show you how to do these things in this slideshow. Instead we will focus on producing the true shapes.

To find the True Shape, project the cut points away from the Front Elevation at right angles to the cut. 2 Draw a datum line on the True Shape parallel to the cut line of the Front Elevation and at right angles to the lines just projected. Also add a datum line to the plan. 3 1 1 3 6 5 4 2 /5 /4 /6 /2 4 Measure the vertical distances from the datum to each of the cut points. Transfer these sizes onto the True Shape. 6 5 6 5 4 3 2 1
