If you have a cluster of points selected like this:

UV sphere

how do you align the points so that they create a flat plane?

You can achieve this by scaling the points along a perpendicular (Normal) axis:

Via Keyboard:

  • Alt+Space: Change Transform orientation to Normal
  • s: Scale selected
  • z, z: The axis to scale on; the first 'z' specifies the global axis. Pressing again specifies local.
  • 0: The amount to scale by
  • Enter: Confirm the action

Via Mouse:

Then you need to left click anywhere in the scene to confirm and modify the properties of the tool.

Change Resize properties

And you will get all the points aligned.

    You can do this of course also just in global space, instead of normal, or any other. If you press the axis letter only once, you'll be in global, pressing the axis letter twice makes scaling use the selected transform space (view, local, gimbal, normal or stay in global if that's selected). What you end up choosing depends on what you need, of course. – jesterKing May 23 '13 at 10:29

    Note this is also doable with the Loop tools addon – gandalf3 Sep 22 '13 at 03:22

If you scale the vertices to 0 along a specific axis, you can make them flat. For example, if you want to flatten some vertices along the X axis, you would press S (to scale) > X (for the X axis) > 0 (to scale them to zero).
