Size and grid units

Ok, I am trying to scale an object with a script. I used obj = Blender.Object.Get(“Cylinder”) and tried to scale it a certain number of units with obj.ScaleZ = 5.0

It isn’t 5 grid units high, so what is the correlation between the two?

Thanks for the help.


it’s a relative scale. That means it will be 5 times larger on the Z axis than originally.
