Worked Solution & Example Answer:C-3. The 3D graphic on the right shows an electric guitar and a guitar case - Leaving Cert DCG - Question C-3 - 2016
Step 1
(a) Draw the given views.
Answer
-
Draw the Elevation: Start by sketching the elevation view based on the provided figure. Ensure that the dimensions are accurately represented, including the curves and angles. Use appropriate tools such as a ruler and compass for precision.
-
Draw the Outline Plan: Next, draw the outline plan as depicted in Fig. C-3. Follow the measured dimensions closely.
-
Complete the Plan: Finally, refine your plan by adding any additional details that are necessary, such as joint lines and specific contour shapes.
Step 2
(b) Project an end view of the case.
Answer
-
Determine Heights and Widths for End View: Analyze the given dimensions and shape from the elevation. Measure the heights and widths accordingly to create an accurate representation.
-
Complete the End View: Using the determined dimensions, craft the end view. Make sure to highlight the edges and any necessary contours of the guitar case to maintain clarity.
Step 3
(c) Draw a one-piece surface development of the case.
Answer
-
Layout of Surface Development: Start with a suitable layout for the surface development, ensuring that all sections are considered, including both bottom and top surfaces.
-
Develop each Surface Area: Divide the case into sections:
- Bottom Surface Development: Sketch the bottom outline considering all dimensions.
- Front and Back Surface Development: Create front and back views, maintaining angle integrity.
- Chamfered Surfaces: Accurately implement the two chamfered surfaces, ensuring precise dimensions are reflected.
-
Vertical Surface Development: Draw out the vertical sections clearly.
-
Top Horizontal Surface Development: Create a clean sketch of the top horizontal planes.
-
Inclined and Circular Sections: Include the long inclined surface and accurately develop the circular sections into a plan view.
-
Curved Surface Development: Finally, finish with the curved surfaces and ensure the entire surface is well presented in one coherent view.
