Hi danperk, yeah that's another part of the resizing method as well, if the bounding box around the object ends on the x/y construction plane, it will project the scale origin onto that plane so the object stays resting on that plane after it's sized.

That works with any kind of object, not just a line - like if you draw a box that has the bottom of the box on the z = 0 plane, when it's resized it will stay with its bottom on the z = 0 plane.
