How can I change the X, Y or Z transform values of all a curve's control points at the same time? I'm trying to change the X, Y or Z values of all a curve's control points at the same time (while I'm in Edit mode). What I do is to select all the curve vertex points and then on the X, Y or Z fields on the Transform / Median tab I change the value. When I keep selected all the points at the same time the value is correctly changed, but when I select each control point, I see that the old value is still there. 

Let's take this post :

How to change location, rotation, scale and dimensions of more objects at the same time?

The user Jan Kadeřábek said to:


  
  Select all the objects
  Click the input field while holding Alt
  Enter the value
  


I thought that it could also work in this situation, but it does not. Maybe because it was in Object mode, instead now I'm in Edit mode?
A common trick to align things is to scale to zero on an axis.


Select multiple control points
SX0 to align them on the x axis
Change the x axis value to the desired value
