Autodesk Inventor 11 Essentials Plus

Instructors Guide - Questions & Answers

by
Daniel T. Banach, Travis Jones & Alan J. Kalameja
Introduction Notes
To ensure students will get the most out of this class confirm that all the students are proficient in the basic use of Windows commands and operations. This book does not cover basic Windows operations. To give your students a better understanding of Autodesk Inventor's power and capabilities, present to the class the creation of a simple part and assembly. This will show the students the ease of use and power behind Autodesk Inventor.
When working through this book each student should work through all of the tutorials and exercises on their own, this will build proficiency. Each chapter builds on the previous chapter. As the students complete each tutorial and exercise they should feel free to experiment with other methods of completing the tutorial and exercise. The geometry in the first few chapters is simpler in nature to ensure the students understand the methodology of Autodesk Inventor. As the book progresses, the amount of help given in the tutorials and exercises will decrease.
Project Exercises
Near the back of each chapter is a self-paced step-by-step project exercises are found at the end of each chapter and provide an opportunity for you to work through real-world modeling, assembly and documentation tasks. The geometry used in the project exercises will flow from chapter to chapter utilizing the functionality you learned in that chapter. The project exercises are based upon a coating system gripper station design. The specifications for the design define a modular gripper station that can be cycled through several cleaning, coating spin and curing stations. All stations need to work within a particulate free laminar air flow environment.
Applying Your Skills Exercises
After the Project Exercise in chapter 2 – 10 there is an Applying Your Skills exercise(s) which is an exercise that allows the student to complete the exercise with limited amount of instruction. The exercise reinforces the topics covered in that chapter.

To review the design in more detail, open the IV11-CH1-PE-Overview.dwf file found in the following location: Your Drive:\IV11 Essentials Plus\Exercises\. The DWF file represents the finished assembly.

• Project files: For this book a simple project file will be used. As an advanced exercise you may want to have the students do a group project that utilizes the multi-user environment.
• Application Options:  Application Options are explained throughout the book when a section is introduced. Since there are many options you may want to introduce the options that are relevant to your students.
• Design Support System: The Design Support System is a powerful tool. Show how the help system can help the student gain proficiency and work through errors.
• User Interface: The User Interface of Autodesk Inventor was designed to be clean and easy to use. Introduce the students to the different aspects of the layout including the Browser, Status Bar, Command Bar, Standard Toolbar, Panel Bar, tool tips, pull down menus, context menus and graphics window.
• Wheel Mouse: Teach the students how the wheel works for zooming and panning. In Autodesk Inventor the wheel is opposite of AutoCAD.
• Units: Autodesk Inventor utilizes true units, it is important that the students understand how units can be used in different design scenarios. Demonstrate how millimeters and inch data can be used in a single part.
• Sketching: Sketching is the foundation for creating parts, make sure that each student is proficient in sketching before they proceed onto the next chapter.

Projects are text files that contain search paths to find files that are needed for a given project. With these search paths, all the needed files can be located when an assembly, drawing, or presentation file is opened.

2 True___ False___ Only one project can be active at any time.

True

3 List the sequence of the locations searched when a file is opened in Autodesk Inventor.

• Library Path searched, only  if it is a library part
• Workspace
• Local Search Paths in the order listed in the project file
• Workgroup Search Paths in the order listed in the project file

4 True___ False___ Autodesk Inventor stores the part, assembly information, and related drawing views in the same file.
False, While creating parts, assemblies, presentation files, and drawing views, that data is stored in separate files with different file extensions.

5 True___ False___ Press and hold down the F4 key to dynamically rotate a part.

True

6 True___ False___ The Save Copy As command saves the active document with a new name and then makes it current.
False, the Save Copy As command saves the active document with a new name but it does NOT make the new file active.

7 List four ways to access the Help system.

• Press the F1 key and the Help system gives you help with the operation that is active.
• Click an option on the Help menu.
• Click a Help option on the right side of the Standard toolbar.
• In any dialog box, click the "?" icon.

8 Explain how to create a shortcut.

• In the Customize dialog box click in the Shortcut area of the tool that you want to change.
• On the keyboard, press the key(s) that will be the shortcut. A single letter or number can be used. You can also use the SHIFT, CTRL, and ALT keys and a letter or number. The ALT key can be combined with the SHIFT and/or CTRL key(s) and a letter or number. The ALT key CANNOT be used with only a letter.

3. Press ENTER to create the shortcut.

 

9 True___ False___ The Look At tool changes the viewpoint to an isometric view.
False, The Look At tool changes the viewpoint so you are looking parallel to a plane, or rotates the screen viewpoint to be horizontal to an edge.

1 True___ False___ When sketching, constraints are not applied to the sketch by default.
False. While sketching, small constraint symbols appear that represent geometric constraint(s) that will be applied to the object. If you do not want a constraint to be applied, hold down the CTRL key when the point is selected.

2 True___ False___ When sketching and a point is inferred, a constraint is applied to represent that relationship.
False, When inferred points are selected, no constraints (geometric rules such as horizontal, vertical, collinear, etc.) are applied from them. Using inferred points helps create more accurate sketches.

3 True___ False___ A sketch does not need to be fully constrained.
True, Autodesk Inventor does not force you to fully constrain a sketch. It is recommended to fully constrain a sketch, however, as this will allow you to better predict how a part will react when dimensions values are changed.

4 True___ False___ When working on a mm part, you cannot use English units.
False, The default unit for any value can be overridden by entering in the desired unit.

5 True___ False___ After a sketch is constrained fully, you cannot change a dimension’s value.
False, To edit a dimension that has already been created, double-click on the value of the dimension and enter a new value in the Edit Dimension dialog box.

6 True___ False___ A driven dimension is another name for a parametric dimension.
False, A driven dimension is a reference dimension. It is not a parametric dimension it just reflects the size of the points to which it is dimensioned. A driven dimension will appear with parentheses around the dimensions value, like (30).

7 If you use the Auto Dimension tool on the first sketch in the part, the sketch will be constrained fully.
False, If you use the Auto Dimension tool on the first sketch in the part, two dimensions or constraints will be required to fully constrain the sketch. Constrain or dimension the sketch to the projected part orign or use the Fix constraint, or constrain or dimension to the projected origin planes, or axis to remove the two required dimensions.

8 True___ False___ You can only import 2D AutoCAD data into Autodesk Inventor.
False, many file types can be imported into Autodesk Inventor, including the following files types; AutoCAD (2D and 3D), AutoCAD Mechanical, Mechanical Desktop, SAT, STEP, PRO/E, DXF, and IGES.

9 Explain how to draw an arc while still in the Line command.
While using the line tool move the cursor over an endpoint and a small circle will appear at that endpoint. Click on the small circle, and with the left mouse button pressed down, move the cursor in the direction that you want the arc to go. Depending upon how you move the mouse, up to eight different arcs can be drawn.

10 Explain how to remove a geometric constraint from a sketch.
Click the Show Constraints tool from the Sketch Panel Bar. Select an object and a row of constraint icons
will appear, move the cursor over a constraint icon, the objects that are linked to that constraint will change color. Then, either click on it and then right-click, or right-click while the cursor is over the constraint and select Delete on the menu.

11 Explain how to change a vertical dimension to an aligned dimension while create create it.
The technique to change the constraint is called scrubbing. To place a different constraint while sketching, move the cursor so it touches (scrubs) the other object to which the constraint should be related. Move the cursor back to its original location and the constraint symbol changes to reflect the new constraint.

12 Explain how to create a dimension between two quadrants of two arcs.

• Start the General Dimension tool.
• Click an arc or circle that includes one of the quadrants to which it will be dimensioned.
• Move the cursor over the quadrant of the second arc or circle to which it will be dimensioned.
• Move the cursor over the quadrant until the constraint symbol changes to quadrant.
• Click and then move the cursor until the dimension is in the correct location, and click.

True, however only the parameter name and value fields are required.

8 Explain how to suppress a patterned occurrence.
To suppress a patterned occurrence, move the cursor over an occurrence in the pattern and right-click. A menu will appear, click Suppress Element(s) and then select the occurrence (s) that will be suppressed.

9 What is the difference between a Model Parameter and a User Parameter?

• Model Parameters are automatically created and assigned a name when a sketch dimensions; feature parameters such as extrusion distance, draft angle, or coil pitch; and the offset, depth, or angle value of assembly constraint is created. Autodesk Inventor assigns a default name to each model parameter as it is created.
• User Parameter are manually created in the Parameter dialog box.

 

10 What is a reference parameter?
This A reference parameter is created automatically when you create a driven dimension. Autodesk Inventor assigns a default name to each reference parameter as you create it. The default name format is a ‘‘d’’ followed by an integer incremented for each new parameter. You can rename reference parameters via the Parameters dialog box.

False, Named parameters are automatically added as size parameters, but can be removed from the parameters of the iFeature if desired.

6. What happens when you create a table-driven iFeature and one of the original parameters contains a list of values for the parameter?
A corresponding member is added to the iFeature table for each value that was specified in the List. For example, if a parameter contained a list of three values for a dimension, there would be three individual rows created in the iFeature table.

7. True False – A Design View can control the display style (shaded or wireframe) of an assembly model.
FALSE. While design view representations can control component visibility, color settings, zoom magnification, and viewing angle, they do not control the display style of an assembly model.  In other words, if you switch to wireframe, all design view representations are displayed in wireframe mode
8. What is the purpose of a positional representation?
Positional representations are used to show an assembly model in different positional states. They can be used to show a motion study of an assembly model. Each motion segment or kinematical state can represent a different position of the assembly and each state can be saved to a positional representation.
9. When would you want to make an assembly have the Flexible property?
The Flexible property is used when there are multiple instances of a sub-assembly in a main assembly that need to be shown or behave independently of each other.The flexible property allows the same instances to function independently of the other instances.
10. What is the purpose of the Capacity Meter and what information does it display?
The capacity meter displays the number of occurrences in an active assembly file and the number of files in the session. It also displays the amount of free memory that is available to the system as well as the amount of committed or used memory.
11. True False – Creating features in the context of an assembly will update the individual parts that make up the assembly automatically.
FALSE.  When an assembly feature is created in the context of an assembly model, the individual parts that make up the assembly will not automatically update to reflect this created feature.
12. True False – A 2D design layout consists of a series of 2D sketches that are constrained to 3D parts in an assembly file.
TRUE
