Worked Solution & Example Answer:The 3-D graphic on the right shows lollipops which are to be distributed as promotional gifts at a trade show - Leaving Cert DCG - Question B-3 - 2014
Step 1
Draw the given plan and elevation of the lollipop.
Answer
-
Begin by sketching the top view of the lollipop, which consists of a circle representing the sphere's top surface. The center of the circle should correspond to the stick's location, which protrudes vertically from the cube.
-
Next, draw the elevation view. This will include the vertical cylinder representing the stick and the circular cross-section of the sphere above it. Ensure that the sphere's diameter is accurately represented in relation to the stick’s diameter.
Step 2
Draw the given auxiliary elevation.
Answer
-
To create the auxiliary elevation, first, draw line X-Y, parallel to the stick.
-
From the end of line X-Y, project perpendicularly to illustrate the positioning of the stick at the indicated angle of 45 degrees.
-
Complete the auxiliary elevation of the lollipop by including the sphere's diameter and ensuring a correct representation of the contours.
Step 3
Complete the plan and elevation to include the cube-shaped packaging.
Answer
-
Start by projecting lines from the auxiliary elevation to the plan, ensuring the cube's dimensions are marked correctly.
-
Establish the correct widths in the plan to accommodate the hidden details of the cube-shaped packaging.
-
Utilize projection lines from the elevation to accurately depict the packaging from both the top and side views.
-
Transfer heights from the plan to the elevation to finalize the dimensions and position of the cube surrounding the lollipop.
-
Ensure completion of the correct elevation to reflect the hidden detail of the stick in plan and elevation, verifying proper scaling and proportions.
