    • Using Joints in Inventor FusionHow to model realistic mechanisms easilyOctober 27, 2012© 2007 Autodesk 1
    • What is Inventor Fusion?• Inventor Fusion is a new CAD product from Autodesk• It is designed to be simpler to use and easier to learn than other CAD tools• Key features: • Mac O/S support • Direct geometry modeling: • Shape creation using familiar tools, but without the complexity of parametric, history-based design • Simple editing using interactive tools directly on the model • Mechanism design using Joints • Allows you to create assemblies using familiar concepts of joints, instead of traditional mate/flush/align constraints • This will be the main focus of our class today© 2007 Autodesk 2
    • Fusion Modeling• Quick introduction to basic modeling techniques and concepts• Component hierarchy • Multiple components, all in a single file • Each component can have multiple bodies • A body can be solid or surface• Body modeling • Geometry creation: • Primitive shapes • Sketch/Feature creation • Geometry modification • Features • Press/Pull and Tweak Faces• Construction geometry© 2007 Autodesk 3
    • Modeling Demo© 2007 Autodesk 4
    • Fusion Joints for mechanism• Joints apply only to components• Joints allow you to define how two components will move with respect to each other• Supported types:• Most common are “Slider” and “Revolute” • Most mechanisms can be designed using just these two• “Rigid” joint is a special case: used to glue or weld two components together© 2007 Autodesk 8
    • Simple example – robotic claw• Let’s look at simple example that illustrates the basics, using only a single joint type: “Revolute”© 2007 Autodesk 9
    • The Add Joint command• Command inputs: • Select geometry on the two components (first one will move to the second) • Select the joint type • OK!© 2007 Autodesk 10
    • Joints Demo© 2007 Autodesk 11
    • Two intermediate topics• Joint Limits • Sometimes you want to restrict the movement of your joints• Motion Relationships • Sometimes you want to make two joints move together© 2007 Autodesk 12
    • Another Demo© 2007 Autodesk 13
    • Advanced Joints• Contact sets• Motion studies© 2007 Autodesk 14
