The 3D graphic and the enlarged balloon detail shows part of a wooden fence which surrounds a patio - Leaving Cert DCG - Question B-1 - 2010

The elevation of the rectangular post should display its height (100 mm) and width (20 mm). Keep the drawing clear, showing how the post relates to the surrounding rails.

For the elevation of the square rail, draw another rectangle with equal sides measuring 20 mm. Represent its thickness accurately to show how it interacts with the post.

The plan view of the square rail should intersect with the projecting lines from the post. Draw it squarely aligned, showing both intersection points.

For the end view, illustrate how the rail and post connect from this angle. Ensure accurate representation of all edges and points of intersection to clarify their relationship.

Begin projecting lines from the left-hand side of the plan for both the post and rail. Maintain parallel lines extending vertically and horizontally.

Identify and mark the key points from the elevations on your drawing to accurately display where the post and rail meet.

Finalize the left-hand side of the elevation by ensuring all component heights and widths are accurately depicted.

Repeat the process of creating projections from the right-hand side of the plan, mirroring the earlier projections for consistency.

Locate corresponding points in elevation, mirroring those identified on the left-hand side to ensure alignment.

Complete the right-hand side of the elevation, ensuring clarity and correct representation of dimensions.

Include the hidden details that show how the rails interconnect within the frame of the posts to provide a comprehensive view.

Final presentation should be clear and neatly drawn, with all necessary lines and intersections highlighted. Ensure dimensions are included as required.
