In this lesson, you work with a scene we created for your use. In the first steps of this lesson, you open the scene and view the various elements that have been created for your use.

1. Make sure you’ve done the steps in Preparing for the lessons.
2. Open the scene file named IK_MechArm.mb.

   This file can be found in the GettingStarted directory that you set as your Maya project:

   GettingStarted/Anim/IK_MechArm.mb

   The scene contains a model of a mechanical arm and a cargo box to be moved by the arm. The components of the mechanical arm include:

   • A cargo magnet cup on the end
   • Three arm segments
   • A base for the arm to swivel about
   • A four-legged base for the assembly

     

To work with this model using IK you must create a hierarchy for it.
