Playing with green cubes
In this article, I use the Select tool (A) and Scale tool (B). When using the Scale tool, a yellow box with green handles appears. Click any of the handles to manipulate the yellow box (and thus its contents). When you move a cube, that cube and its counterpart will turn red. If you’d like to rescale a component from its centrepoint, hold Ctrl while moving a cube. You can also define an exact scaling factor by entering a value in the Scale box.
