Thanks @joselaks! The functionality is included, but not documented - so it is not obvious. Perhaps it’s easier to share a screen to demo this? I am generally online during all working hours Sydney time (and them some) in the IRC live chat: https://blenderbim.org/community.html
The ability to do construction documentation is extremely important, but still very raw. I am happy to say that for very, very small projects, I am able to apply it already, so perhaps with increased streamlined workflows and optimisation of the cutting process, it will grow to larger projects.
Here’s another sneak peek of some documentation produced with BlenderBIM (yes, these are colourful, but I can also produce pure black and white style drawings if it is appropriate for the job):
