I'm not sure soft limits should really be used for this, just to keep the individual axes from hitting the ends. Some advanced controls have "clamp limits" where various combinations of axis positions are indicated as "don't go here". You could set up regions around your vise jaws, for instance, to keep the machine from cutting into the vise. This is a WHOLE lot more involved than just soft limit values for individual axes. For instance, it would allow the tool to pass OVER the vise jaw, but prevent the tool from passing THROUGH the jaw. This would be a nice feature to have, but I think it is an entirely different thing to do than just handling soft limits on the axes.
