16.
A design team is working on creating a new energy-efficient light. They have completed the following steps:They asked questions, did research, and determined the design requirements for their solution.They brainstormed, sketched their ideas, compared them, and identified the best possible solution to pursue.They created detailed technical drawings, including CAD drawings, to use to produce their solution.What is the next step of the design process that they should complete?
a)
Develop and Test Solution
b)
Present the Solution
c)
Evaluate Solution
d)
Design a Solution
17.
Why might a designer or engineer use an isometric sketch rather than a perspective sketch to communicate their idea?
a)
An isometric sketch uses dimensions to communicate height, width, and depth, whereas dimensions cannot be used in perspective sketches
b)
An isometric sketch has more accurate design details, because it shows a view similar to what our eyes actually see
c)
An isometric sketch has no vanishing points and all horizontal and vertical lines are parallel to show details on three sides of an object simultaneously
d)
An isometric sketch can be drawn using multiple vanishing points, depending on the complexity of the object
