At the end of Section 1 Lecture 6, the practice session has you add a box, then rotate it about 45 degrees, then apply the rotation so you can then scale it on a single axis to create the diamond shape.
In 3ds Max, the program I’m most familiar with, after you rotate the box, you can just scale it on one axis in the World coordinate system to create the diamond shape. No need to apply transforms (aka Reset XForm in Max).
My question: Is it possible to use the World coordinate system in Blender to replicate how Max works? I tried, but just got uniform scaling on the horizontal plane.
