Unable to make a door? Subtractive not working?

I have used subtractive before in 4.6 and was able to make a door way now in 4.7 no longer works?

Hi James,

Everything appears to be working on my end with the latest 4.7 Preview 8 release.

Make sure that you’ve changed your brush type to subtractive in the details panel when the brush is selected.
