2. Orthographic Projection
The Elevation of a hexagonal pyramid is given below
The pyramid is cut by a plane at 60° and the upper section is removed
Notice that this is similar to a previous problem but the cut is in a different plane

3. Starting the End Elevation
Draw the outline of the End Elevation and number the edges as shown

4. Drawing the Plan View
Draw vertical generators from the cut surface to allow the drawing of the Plan
Notice that the Plan shows 3 sides while the Elevation only shows 2 sides

6. Completing the End Elevation
Construct the lines 5–6, 4–1 and 3–2 on the End Elevation as shown,
these are TRUE LENGTHS and come from the Plan View

8. Drawing the True Shape The Datum Line is parallel to the cutting plane
Construct generators at right angles to the Datum Line as shown
Draw the True Lengths 5-6, 4-1, 3-2 as measured from the End Elevation in the last slide
