1. Which rollout is used to loft multiple shapes?

• The Path Parameters rollout is used in conjunction with the Creation Method rollout to loft multiple shapes.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

2. What does current level mean?

• The current level is where any shape “put” on the path of a loft object is placed.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

3. What are the three ways the value in the Path: spinner can be displayed?

• The value in the spinner can be expressed as a percentage of the path length, an absolute distance from the first vertex, or as path steps.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

4. How is the current path level indicated in viewports?

• The current path level is indicated in viewports by a small yellow X.

5. What is the purpose of the value in the Snap: spinner for loft objects?

• The value in the Snap: spinner is used to set snap increments for adjusting the current level on the path in the Path: spinner.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

6. Which radio button(s) allow a virtually unlimited number of shapes on the path of a loft object?

• Percentage and Distance

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

7. What is the purpose of the Pick Shape button at the bottom of the Path Parameters rollout?

• It allows you to set the current level of the path to that of the shape you pick.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

8. How can you add loft shapes to an existing loft object?

• After creating the loft object, keep the loft object selected.

• In the Path Parameters rollout, use the Path: spinner to move to the level where you want to add the next shape.

• Finally, pick the Get Shape button in the Creation Method rollout and pick the shape(s) you want to add.

• If the loft object is already created and is unselected, you must use the Modify tab in the Command Panel.

9. What do deformation tools allow you to do?

• The deformation tools allow you to fine-tune a loft object by applying a deformation.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

10. How can you apply a deformation when creating a loft object?

• A deformation cannot be applied while creating a loft object. The deformation tools must be accessed through the Modify tab of the Command Panel after the loft object is created.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

11. Which deformation tools use a dialog box with a common layout?

• Scale

• Twist

• Teeter

• Bevel.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

12. What does the layout of the Deformation dialog box look like?

• The interface of the dialog box resembles a graph of the deformation.

• A ruler along the top of the graph indicates the current percent position on the loft path.

• A scale along the left side of the graph indicates the percentage of the deformation being applied.

• The deformation grid in the middle of the dialog box is used to insert, move, or scale control points on the deformation curve.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

13. What is the purpose of the Make Symmetrical button in the Deformation dialog box?

• It allows you to apply the same changes to the deformation to both the X and Y axes.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

14. In what color are the X and Y axes displayed in the Deformation dialog box?

• By default, the X axis appears as a red line. The Y axis appears as a green line.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

15. What does the Reset Curve button do in all of the Deformation dialog boxes except the Fit Deformation dialog box?

• It removes all added control points and reverts the curve to the default setting.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

16. What are the three types of control points that can be used on a deformation curve?

• Corner

• Bézier-smooth

• Bézier-corner

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

17. What does the fit deformation do?

• It forces a loft object to fit inside profile shapes you define.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

18. How do you remove a twist from a loft object created from a square and a circle shape?

• At the sub-object level, align the vertices of the shapes on the loft object using the Compare dialog box and the Select and Rotate button.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

19. What are the two conditions that must be met for morphing two objects?

• The objects must both be either mesh objects or patch objects, and they must have the same number of vertices.

From: CHAPTER 9– Advance Compound Objects3DS MAX AND ITS APPLICATIONS

20. With what type of object is the mesher compound object designed to be used?

• a particle system
