Worked Solution & Example Answer:The image on the right shows the Louis Vuitton retail store in Singapore - Leaving Cert DCG - Question C-3 - 2019
Step 1
Draw the given elevation, plan and view.
Answer
-
Using the provided dimensions, sketch the elevation according to the scale 1:100. Ensure that the correct angles and measurements are accurately represented.
-
For the plan view, represent the building from above. Mark the locations of surfaces A, B, and C, indicating their orientation and shape clearly.
-
Finally, create a side view that corresponds with the elevation and plan views, maintaining proportional dimensions.
Step 2
Determine the dihedral angle between surfaces A and B.
Answer
-
Identify the line of intersection of surfaces A and B on the new plane X1Y1.
-
Project both surfaces onto this line and note their intersections.
-
Construct a perpendicular to the line of intersection where necessary, then use the projections to find the angle between the two surfaces at their intersection.
-
The dihedral angle is measured using geometric or trigonometric methods based on these projections.
Step 3
Determine the true shape of the vertical surface C and the true shape of the inclined surface B.
Answer
-
To find the true shape of surface C, project the points of surface C vertically onto a new plane. This will allow for a true representation of its dimensions and angles.
-
For surface B, create a reference plane perpendicular to the inclined surface and project the points accordingly to capture its actual shape. Mark all key dimensions clearly to reflect the true surface.
Step 4
Determine the horizontal and vertical traces of surface B.
Answer
-
Start by identifying the required horizontal trace of surface B by projecting it onto the X-Y plane. Ensure the projection accurately reflects the boundaries of the surface.
-
Next, to find the vertical trace, select key points from the horizontal projection and construct lines that represent the vertical cuts of surface B, ensuring all dimensions are correct.
-
Finally, draw the required vertical trace on the appropriate plane, maintaining clarity and accuracy in representation.
