I would like to know how to set a custom center/pivot point for the "copy location constraint”. So when we set the X/Y/Z invert of the copy location constraint, two objects can move toward the opposite directions within a certain area. Please see the simulation video: https://drive.google.com/open?id=1bSmByVFAe1Na12U35pxzNZnx7k05Q2Zu

Currently, by default, the center point is on the world origin point (coordinates X,Y,Z=0,0,0), so when I set the copy location constraint with X/Y/Z invert, two objects are separate far far away according to the center point is on the world origin point. please see the recording video of the result of default setting: https://drive.google.com/open?id=1cqONcr4gopfTiHIwQ96gmEb_yy9scNxC

Please download the testing blender file: https://drive.google.com/open?id=1Lj128BZKfHOe8av16_At_7vneEjoKNVW

Thank you very much,

Thank you.

Please see the reference images and blender file below :

You can use drivers as constraints: in your example the cursor is at 0,0,4. So X and Y can be managed by the copy location (inverted) constraint. Your new Z value has to be 4 - (Zold - 4). So you can set the Z driver as 8 - Z.

The same can be done with different X and Y values.

Another way can be set the copy location constraint in local space (instead of world space), check the offset option, then move both meshes to the pivot point (Shift S - selection to cursor).
