adobe illustrator - How to align several objects on the same x coordianate?

I have several objects with different x coordinates. If I select them all and transform them to a x coordinate Illustrator sets the x coordinates relative to the selection as a whole. I want to set the x coordinate for all objects the same.

So: The objects should be in line below each other, starting at the same x. Is there any way to do it? I don't want to set the x coordinate for the objects separatly.

Answer

Use the Align tool Window > Align (Shift + F7) and select Horizontal Align.

Make sure you select what you are trying to align it to.

• 
  

  Artboard - Align it all with the center of the artboard

  
  


• 
  

  Selection - Average it out in the middle (all will still be perfectly aligned)

  
  


• 
  

  Key Object - Align it to the selection which has the Bold outline (you can change the key object by just clicking on a different object)
