Please assist me with the following in Maya.

I have an Ik arm that needs to pick up an object, lets say a sphere.

The arm must move to the position of the sphere, pick it up (point constraint, with a weight of 1) move to another point in the scene, drop the polySphere (constraint weight to 0) in the new position and move freely away with out affecting the sphere.

If I do this the sphere will bounch back to it's orginal position in the scene.
So then I use the "set reset position". This makes the second (drop of) position of the sphere the new position and when I move the time slider to the begining of my animation the sphere jumps back also to the second reset position.

How do I make this work?

if this is in Maya, you need to have at least 2 items that the sphere is constrained to.. and one must always be 1 for it to work correctly. What I usually do is create a locator for each "parent", including the world. For your example, that would be 3 locators.. one called world_1, another called hand, and another called world_2.

First parentCosntrain the sphere to world_1 and make sure it's weight is 1. Then when you are ready for the hand to pick it up, parentConstrain the sphere to hand and set the weight of world_1 to 0 and hand to 1. Then when you're ready to drop it. parentconstrain the sphere to world_2 and set it's weight to 1, and the rest to 0.

that should do it! ;)
