Worked Solution & Example Answer:The 3D graphic on the right shows a piece of sculpture from the entrance lobby of an Irish company, Prism Technologies - Leaving Cert DCG - Question B-3 - 2009
Step 1
Draw the Front Projection of the Sculpture
Answer
Begin by setting up the XY plane. Draw the outlines of the square base solid, ensuring it's at a scale of 1:10. The dimensions provided indicate that the solid's height is 500mm and the base is 250mm x 250mm. Sketch accordingly, with the top view showing the 350mm square prism's penetration into the solid.
Include the relevant hidden lines representing the edges of the sculpture that are not visible from this view.
Step 2
Draw the Top Projection of the Sculpture
Answer
From the top view, illustrate the sculpture's base, making sure to represent the square prism's position accurately. The solid's width should be 250mm and the height from the base to the top is 500mm. Clearly depict where the square prism intersects with the larger sculpture. Use dashed lines for the hidden edges and ensure all angles and intersections are correct.
Step 3
Draw the Side Projection of the Sculpture
Answer
For the side view, represent the height and depth of the sculpture accurately. The square prism should appear to penetrate into the solid, so highlight this intersection clearly. The side should measure 350mm and match up with the outlines from the previous projections. Use appropriate line styles to differentiate between visible and hidden lines.
