Worked Solution & Example Answer:The 3D graphic on the right shows a dog kennel - Leaving Cert DCG - Question B-2 - 2015
Step 1
Draw the given equilateral triangle and the axonometric axes X, Y, and Z.
Answer
To begin with an equilateral triangle, first, determine the length of each side. Draw one side horizontally and use a compass to create the other two sides, ensuring all sides are equal. For the X, Y, and Z axes, orient the X-axis horizontally to the right, the Y-axis vertically up, and the Z-axis at a 30-degree angle to the horizontal axis.
Step 2
Draw the elevation and plan positioned as shown.
Answer
The elevation view should display the front view of the kennel, showing the roof and the opening. Set the elevation according to the given projections, ensuring that the semi-circular opening is visible at the center. For the plan view, project the dimensions from the elevation, placing the kennel outline in the correct position—ensure to label the plan accordingly.
Step 3
Draw the axonometric projection of the sides and roof of the kennel.
Answer
Start by drawing the sides of the kennel based on the dimensions provided in the elevation. Use the appropriate angles to accurately represent the depth. From these, project lines to create the roof by defining its triangular shape, ensuring all lines align with the established coordinate axes for a consistent perspective.
Step 4
Draw the axonometric projection of the front of the kennel to include the semi-circular opening.
Answer
For the front view, accurately depict the semi-circular opening at the designated height and width. Draw the circular section with the correct radius (as referenced) at the appropriate position. Ensure that both the outline of the kennel and the opening harmonize with the other axonometric perspectives established.
