Translation Constraint
The Translation Constraint allows you to set limits on an object’s position and/or copy the position properties from a target object. These properties can be independently activated.
How to create a Translation Constraint
Add a Translation Constraint to an object
Use the Constraints section of the Inspector to add a Translation Constraint to an object.
Choose a target
Use the new constraint’s fly-out menu to select a target for this constraint.
Test that the Translation Constraint is working
Manipulating the target object now causes the constrained object to copy Position properties.
Strength
The Strength property determines how much the constrained object is affected.
A Strength of 0% means the constraint won’t have any effect.
A Strength of 50% means half the value from the target will be applied.
Transform Space
Source Space
Choose whether this constraint should use World or Local coordinates for the Source Space.
Destination Space
Choose whether this constraint should use World or Local coordinates for the Destination Space.
Min/Max Space
Choose whether this constraint should use World or Local coordinates for the Min/Max Space.
Offset
Allows the constraint owner to be manually offset from the constraint source.
Copy X &Y
Allows you to decide if the constraint owner will copy the translation in the X and Y direction. Additionally, use the numerical value to define the rate at which it copies the value.
Max/Min
Use the numerical values to define the minimum and maximum limits of the constraint.
