1. 3D Computer Modeling Using Inventor 15

2. 3D Modeling in Inventor 15 Getting Started This is what you will see when you first open Inventor. Click ON Start Working By doing this you will not see this screen again.

3. 3D Modeling in Inventor 15 Getting Started You can begin a new file or open an existing file with either the New or Open commands on the Launch panel, the Quick Access Toolbar, or the Application Menu. When selecting New, be sure to choose the correct system, either Standard or Metric for your measurements.

4. Inventor Screen Layout

5. Application Menu: Contains common commands for creating, saving, and printing.

6. Inventor Screen Layout Quick Access Toolbar: Provides quick access to frequently used commands.

7. Inventor Screen Layout Ribbon: Controls used for both 2D drawing and annotation and 3D modeling and viewing

8. Inventor Screen Layout Ribbon Tabs: Organized by task, contain task specific buttons and controls.

9. Inventor Screen Layout View Cube: Clickable and draggable interface that is used to switch between standard and isometric views.

10. Inventor Screen Layout Navigation Bar: On screen element that provides access to various navigation tools.

11. Inventor Screen Layout Browser: Maintains a history of the part, assembly, or drawing creation.

12. Inventor Screen Layout 3D Indicator: Shows direction of X, Y, and Z coordinates. Red represents X, Green represents Y Blue represents Z directions

13. Inventor Screen Layout Graphics Window: The active modeling area where parts and assemblies are created and edited.

14. Mouse Buttons Left Mouse Button –Used to select icons, menus, and graphics Right Mouse Button –Brings up additional options –Accepts default option –Ends a process Middle Button/Wheel –Provides quick pan and zoom functions

15. Geometric Constraints Symbols that show alignments to capture the design intent To use Geometric Constraints: 2. Right mouse click in Graphics Window, then select Create Constraint OR 1. Use the commands available from the Sketch panel

16. Geometric Constraint Symbols PerpendicularLines are at right angles ParallelLine is parallel to other objects TangentTouches at one point only SmoothCreate a continuous curve CoincidentConstrains 2 points or point to curve ConcentricArc or Circle shares center point Collinear2 lines lie along the same line EqualResizes to same radius or length HorizontalLine is parallel to X axis VerticalLine is parallel to Y axis FixPoints or curves stay locked in place SymmetryObjects align symmetrically about a line

17. Dynamic Viewing Functions Pan Zoom Zoom Window Zoom All Zoom Selected Dynamic Rotation Look At Located on View Ribbon Tab Used to Zoom and Pan to reposition the sketch ORBIT TOOL

18. Conclusion Why is it important to use constraints when sketching with your 3D modeling program? Constraints are used to draw an object with accuracy. Explain the difference between zoom and pan when using 3D modeling program and describe two ways that you can perform both. Zoom is used to see a specific area on the drawing. Pan is used to move around on the drawing. Use the scroll wheel on the mouse or the navigation bar menus.
