I'm trying to resize a rectangular cubiod, currently 5 meters on it's longest sides and 2 meters on it's shortest sides (as shown in the diagram) I'd like a method that allows me to just set a new length of one edge that proportionally sets the length of the rest of the edges in the cuboid.
So for example: I'd like to be able to type in a new length for one of it's 5 meter edges and make it 2.5 meters. After I do so I need the rest of the edges all to shrink by a half. The result of this example will make the 4 of the edges 2.5 meters long and the remaining 8 edges 1 meter long.
