Week 02: 3D Printing Software Coursera Quiz Answers
Quiz 01: Module 2 Quiz
Q1. To use 3D printing technology, we need to have 3D data.
Q2. In Tinkercad, you can easily get predetermined geometric shapes (eg. Cubes, cylinder, etc) in the “Geometric” session, and you:
- Can change its dimensions (height, width, length)
- Can scale it
- Cannot change its color
- Can move it freely on the design plane
Q3. How can you scale an object uniformly (i.e. scaling in a way that the final proportion of the dimensions will not change):
- Press “Shift” while scaling
- Press “Ctrl” while scaling
- Press “Ctrl + Shift” while scaling
- Press “Ctrl + Alt” while scaling
Q4. To combine/group these two shapes together, which is the best way to position them:
- Two shapes not connected to each other:
- Two shapes are connecting each other exactly on the surface:
- Two shapes are connected by some overlapping parts:
Q5. How do you combine the two shapes together in tinkercad?
- Just click “Group”
- Select one of the objects and click “Group”
- Select both objects and click “Group”
Consider you have these two objects:
If you Select the cylinder and then click on “Hole”, then move the cylinder inside the cube, then select both of them and “Group” them, what will you get?
Week 03: 3D Printing Software Coursera Quiz Answers
Quiz 02: Module 3 Quiz
Q1. Consider the following statements about primitives and sketch based modeling in fusion? Identify all the statements that are true
- For primitive options you can create a shape without sketching;
- Extrude and Loft are two operations during sketch based modeling
- You need to sketch to create a cylinder and a coil using the “Create” options in the “Model” mode
Q2. In which mode can you adjust the geometry that you made?
Q3. You can get a 3d printable file directly out of Fusion, because you can export your model as an STL file
Q4. If I only want to edit the edges of the geometry shapes created, what is the best way to do it?
- Select individual edges and edit them one by one
- No way, because I can only edit the faces and bodies of the shapes
- I can use “Selection filter” under “Select” and choose “body edges”, because in this way I can easily edit only the edges of all my shapes
Q5. True or False: You can insert real parts from McMaster Carr and other hardware retailers directly into the Fusion 360 model.
Q6. This tool allows you to rotate and pan the view of your workspace:
- Data Panel
- Right Click
- Workspace Orient Panel
- View Cube
Q7. The Part Browser (window on the left side of the default screen) keeps track of the following features (select all that apply)?
- Construction objects
- Part histories
- Named views
Q8. True or False: The Timeline in Fusion 360 keeps track of your actions and allows you view or to roll back your model to a previous versions.
Q9. Which of the following are valid operation controls in Fusion 360 when two bodies interact (select three answers)
Q10. What is the first step in creating a sketch?
- Hide previous sketches
- Draw the sketch first using construction geometry, and then draw the actual sketch
- Just start drawing the sketch
- Pick a plane to sketch on
Q11. How do you hide geometry?
- Use parametric modeling
- Use the View Cube
- Use the Timeline
- Use the Browser
Q12. What is the main difference between components and bodies?
- Components are combined to create bodies
- Bodies are used in sculpting mode while components are used in parametric mode
- Bodies are combined to create components
- Components are objects that have been converted from bodies to be used as real parts for an assembly
Q13. True or false: Joints create and promote movement in the Fusion 360 modeling environment.
Q14. True or false: Joints can be created with either bodies or components.
Q15. What is a contact set in Fusion 360?
- Contact sets are the groups of other users who can view or edit a project
- Contact sets are types of construction objects
- Contact sets allow components to behave like real solid objects to prevent unwanted object intersections
- Contact sets are used to define where a joint will be placed

Quiz 01: Module 4 Quiz
Q1. Create a box in the sculpt mode, its edges are
- Smooth, because each face is tangent to its neighbor.
- Sharp, because the box should be the same as the one in the modeling mode.
- Smooth but not continuous
Q2. To select multiple points, edges, and faces, you can hold ____ while selecting them:
Q3. To select multiple faces, if you drag a “selection box”…
- from right to left, you will select all the faces that are contained in and touch the box
- from right to left, you will select only the faces that touch the box
- from left to right, you will select only the faces that are contained in the box
- from left to right, you will select all the faces that are contained in and touch the box
Q4. What would happen if you double click on a face?
- You will select only the face clicked
- You will select the face clicked and the surrounding faces connected
- You will select the entire body that the face is on
Q5. Using ”Subdivide” on faces and using “Insert edge” on edges are two ways of adding faces.

Q3.“Next engine” uses laser light, and can do high resolution scans with accurate and detailed results, but it is time-consuming.
Q4. When using the Photogrammetry method of scanning, you can zoom in and out with your camera to get the best pictures of the still object from different angles of views.
Q5. After 3D scanning, (usually) we get a shell/surface with no volume. It can be printed directly on the 3D printer without modifications.
Q6. True or False: The Xbox Kinect has a fixed focus lens so it works best for scanning certain size objects at a certain distance away.
Q7. The Depth Threshold tool on the Xbox Kinect does what? Choose one.
- It varies the aperture of the lens
- It varies the height and width of the image the camera can see
- It is used to specify how far from the camera the object is in order to limit background noise
Q8. True or False: The Xbox Kinect and Structure Sensor for the iPad both use structured light infrared camera technology to take 3D scans.
Q9. True or False: The NextEngine 3D scanner can take dimensionally accurate scans but takes a much longer amount of time to scan than the Xbox Kinect and Structure Sensor.
Q10. What kind of camera is required for photogrammetry?
- It must be a high quality camera with a zoom lens
- It must be a smartphone camera
- Most cameras will work, including a smartphone camera
- It must be a special 3D camera
Q11. What needs to be done during post processing for photogrammetry in order to prepare the scan for 3D printing?
- Close open surfaces to create watertight object
- Build a mesh using imported photos
- Clean the mesh by cropping unwanted points or surfaces
- All answers are correct
