  <p>What I am trying to do is, to move the camera. For a better workflow I want to parent the camera's position to the position of a Null-Object, also at [0,0,0]. The thing is the camera has to keep its offset from [0,0,0] and just move parallel with the null at [0,0,0].</p>
  
  <p>Can somebody help me?
  Thanks in advance!</p>

Comments.Text: @poor thanks for your reply, the problem is, when I simply parent it with the pick whip, the camera copies the exact same position of the null. What I want is a specific offset to keep form the camera to the null object

  To drive an animation by another layer use the pick whip or the selection list to **parent** it. In the following example the `Camera (layer)` adopts all animation properties of the `Null`.

  Note: `Camera` is a 3d layer in your case, make sure **3d layer toggle** is enabled for the `Null` too.
