[Hammer] A brush drawing feature absent from S2

[SethTooQuick]

In Source 1 hammer, you could select an existing brush to use those dimensions as the ones you'll draw next. So, if you had a block that had a width of 16, height of 64, and length of 128, and you were to draw in the top view, the length and width would get replaced by your new selection, while keeping the height as you're not in the view that can see height.

There are a few issues with this though that I can see. Source 1 didn't allow you to draw in the 3D view, so what should it do there? You still draw only on one axis, so should it act as the top view or should it do nothing and do it's normal behavior?
