I've been trying to implement a move tool similar to the one built into the unity editor. After failing to make it I've spent many hours trying to find a way to do it. I came up with this:

Plane groundPlane = new Plane(Vector3.up, Tracked.position);
Plane rightPlane = new Plane(Vector3.right, Tracked.position);
Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 RaycastHit hit;
 switch (axis)
 
 case Axis.X:
 if (groundPlane.Raycast(ray, out ent))
 
 float deltaPosX = ray.GetPoint(ent).x - lastHitPos.x;
 Tracked.position = new Vector3(Tracked.position.x + deltaPosX, Tracked.position.y, Tracked.position.z);
 lastHitPos = ray.GetPoint(ent);
 
 break;
 case Axis.Y:
 if (rightPlane.Raycast(ray, out ent))
 
 float deltaPosY = ray.GetPoint(ent).y - lastHitPos.y;
 Tracked.position = new Vector3(Tracked.position.x, Tracked.position.y + deltaPosY, Tracked.position.z);
 lastHitPos = ray.GetPoint(ent);
 
 break;
 case Axis.Z:
 if (groundPlane.Raycast(ray, out ent))
 
 float deltaPosZ = ray.GetPoint(ent).z - lastHitPos.z;
 Tracked.position = new Vector3(Tracked.position.x, Tracked.position.y, Tracked.position.z + deltaPosZ);
 lastHitPos = ray.GetPoint(ent);
 
 break;

  You may need to add an offset to the postion depending on where you clicked the arrow. That would keep it from jumping around like that.
