There has been a few times when I have been clipping where I accidentally pressed some combination of keys, and Hammer started showing me measurements for the sides of brushes being clipped in the 2D views, like this:
So my question is, has anybody seen this before? And if they have, do they know how to turn it on, so that I can bring it back when it inevitably goes away again?
This seems like it would be really useful, but whenever it happens I end up accidentally pressing those keys again, making it go away, and I don't know how to bring it back.
