1. use the drawing of the hood to answer the following questions. select the

correct answer from the answer bank below. each selection may only be used
once.
5 points – 1 point each
note: notice the two surface indicators.
3.1 what is the overall width of the hood?
3.2 what is the width of the inclined surface?
3.3 what is the height dimension to the
center of the holes?
3.4 what is the overall height of the hood?
3.5 to what depth should the holes be drilled?

1. basic steps to 3d model a part – arrange the steps (workflow) below in the

proper order to model the part pictured to the right. 5 points – 1 point each
a. apply a new sketch to the back surface and sketch a square
b. constrain and dimension
c. dimension and then extrude - join
d. sketch an “l” shaped profile
e. finish the sketch and extrude

Explanation:

The problem involves 3D modeling steps for a part, which falls under Engineering (a subfield of Natural Science). To determine the order, we analyze typical 3D modeling workflows:

1. First, sketch the base profile (D: Sketch an "L" shaped profile).
2. Then, constrain and dimension the sketch (B: Constrain and dimension).
3. Next, finish the sketch and extrude the base (E: Finish the sketch and extrude).
4. After that, apply a new sketch to the back surface and sketch a square (A: Apply a new sketch to the back surface and sketch a square).
5. Finally, dimension and then extrude - join the new sketch (C: Dimension and then extrude - Join).

Answer:

1. D. Sketch an "L" shaped profile
2. B. Constrain and dimension
3. E. Finish the sketch and extrude
4. A. Apply a new sketch to the back surface and sketch a square
5. C. Dimension and then extrude - Join
