Worked Solution & Example Answer:The 3D graphic on the right shows a child's toy - Leaving Cert DCG - Question B-3 - 2009
Step 1
Draw the given plan and elevation and project an end elevation of the block and peg.
Answer
-
Plan View: Begin by outlining the block's shape in the plan view, using the measurements provided. The block includes various geometric shapes, so be sure to represent them accurately based on the 3D model.
-
Elevation of the Block: Next, create the front elevation. This involves projecting the heights from the plan to ensure that vertical elements are represented correctly. Pay attention to detailing the triangular peg accurately within the block's elevation.
-
End Elevation of the Peg: For projecting the end elevation, focus on the triangular prism's view. Each side should be 60mm, so calculate and draw the angles accurately, ensuring the equilateral nature is maintained.
-
Interpreting Lines: Clearly indicate all necessary lines, such as hidden lines, center lines, and construction lines. Use dashed lines where elements are not visible in the given view.
-
Final Review: Ensure all parts are labeled correctly and check for accuracy in dimensions and projections. Review the scale used and confirm that it is consistent throughout the plans and elevations.
