About Dragging and Taking Snapshots
Use Drag Components to move assembly entities through an allowable range of motion to see how your assembly works in a specific configuration. The following entities can be selected to initiate a dragging movement:
Datum plane
Surface of a rigid body that is not defined as ground
The selected entity is positioned as close as possible to the current pointer location while the rest of the assembly components stay connected to each other.
Controlling the Assembly Movement
To control how the assembly moves during the dragging operation, specify the following:
Drag entity (point or rigid body)
Drag constraints
Lock and unlock rigid bodies
Enable and disable connections
Placement definitions and constraints affect the range of motion.
Using Snapshots
Use the Snapshots tab on the Drag dialog box to display a list of saved snapshots of the assembly in varied configurations. After you move the components to the desired location, you can save snapshots of your assembly in different positions and orientations. Snapshots capture the existing locked rigid bodies, disabled connections, and geometric constraints.
You can use the Drag Components command and take snapshots while placing a component.

Using Constraints
Use the Constraints tab on the Drag dialog box to apply or remove constraints. After you apply a constraint, its name is added to the constraints list. You can turn the constraints on and off by selecting or clearing the check box next to the constraint. Use the shortcut menu to copy, cut, paste, or delete the constraint.
Locking Assembly Rigid Bodies
Assembly rigid bodies can be fixed relative to a single lead rigid body. The locked rigid bodies will behave as if glued together, with no movement between them. The rigid bodies do not need to be touching or adjacent to be locked together.
