1. Constraining Assemblies in Inventor: Applications in MAE3 Dor Ashur Dr. Nathan Delson

2. Lecture Overview Quick review of last week’s key points Assembly Basics Types of Constraints Assembly Drawings Animations

3. Quick Review of last week Advantages of Solid Modeling: Great Visualization Model is Parametric Automatic and Updating Drawings 3D rapid prototyping Integrated 3D Analysis ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

4. Inventor Basics: File Types Sketch Part:.ipt Drawing:.idw ReviewBasicsConstraintsAssembly DrawingsAnimation Preview Assembly:.iam

5. Assembly Basics: Multiple small assemblies can be added together as well to create a large assembly. ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

6. Constraints Basics Constraints can be made between any two of the following: Face (Origin plane, flat, curved or cylindrical) Edge (straight, round or circle) Point A “grounded” constraint makes that part unmovable. ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

7. Types of Constraints Mate Flush ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

8. Types of Constraints Angle Tangent Outside Inside ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

9. Types of Constraints Insert a shaft into a hole automatically Mate Center line of two circles ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

10. Types of Constraints Grounding makes part immobile Must make at least one part grounded to constrain assembly All constraints can have an offset value ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

11. Assembly Drawings Any changes made to the 3D model automatically are updated in the projections Automatic parts list Automatic balloons which reference a part number on the parts list Automatic Drawing information ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

12. Animation of Assemblies Driving Constraints: Shows a very quick animation of one constraint changing Right click on the constraint in the model panel and choose drive constraint ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

13. Animation of Assemblies Constraints: Angular between the bottom of the cube and the green surface. Mate between one of the cube’s edges and the green surface. By specifying the time and amount by which these constraints change, one can animate an assembly. ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

14. Animation of Assemblies - Cameras Inventor also allows you to animate the camera angle !! Each team will make an animation of their robot in motion ReviewBasicsConstraintsAssembly DrawingsAnimation Preview

15. Short Tutorial Each section go over the assembly of last weeks tutorial parts in detail.
