The 3D graphic on the right shows the intersection of a wall and a pillar - Leaving Cert DCG - Question B-3 - 2013

For the wall plan, reference the given dimensions and ensure to represent the wall correctly with a width of 20 units and height of 100 units. The wall should connect to the pillar, reflecting the 3D arrangement shown in the figure.

For the elevation of the wall, present it as a vertical rectangle on the right side of the pillar in your drawing, ensuring correct proportions. Label it with its dimensions and ensure it appears as it would in a true elevation view.

In completing the elevation drawing, include the full height of the wall and pillar clearly, ensuring you add texture or detail to indicate the wall's construction material as shown in the 3D graphic.

From the left-hand side of the plan drawing, create projection lines extending upwards to denote how the pillar and wall elements align in elevation. Ensure the projections reflect the actual dimensions.

Mark the intersection points on the LHS elevation view corresponding to the projections drawn. This step involves taking care to align the measurements accurately.

Finalizing the LHS elevation means connecting your points with straight lines to visualize the left-hand side appropriately, ensuring the interactions are clear.

Similarly to the LHS, draw projection lines from the right-hand side of the plan to show how the wall intersects with the pillar.

Identify and mark the corresponding points on the right elevation based on your projections from the RHS.

Close up the right-hand side elevation so that it accurately captures all structures, ensuring they line up with the projected points and maintain proportions.

Using a straightedge, take measurements from the plan and accurately reflect these widths in the elevation to ensure scale consistency.

From the elevation drawing, project the height dimensions onto the end view to correlate with what will be represented in that view.

The end view should display the wall's thickness and height as it appears end-on. Ensure dimensions are consistent with previous drawings.

Finalize the end view by cleaning up any overlapping lines and ensuring all dimensions are clear, providing a clear overview of how the wall and pillar interact from this perspective.

Ensure that all drawings are neat, labeled, and drawn to scale. Add any necessary notes or legends that would aid in understanding the drawings.
