I posted an update on my work with the Homemaker Blender add-on. It's an interactive pointy-clicky tool for designing buildings (the main Homemaker tool is 100% command-line automation, this hasn't changed)

Hey maker people! It's clear now that I'm never going to get around to prototyping this idea for a cheap heat recovery unit. If it works, you can ventilate your building without spending more on heating.

Idea for a ventilation fan with a *cheap* heat exchanger made from kitchen foil, foam rubber, wood, and lots of glue

I actually quite like k9 mail, the status messages are fun: "Next poll 4 days ago"

I knew there was a reason I left the lights on the Christmas tree

All the coriander plants bolted, but now I have a jar of seeds (also contains non-zero number of tiny snails)

This is a proof of concept Blender add-on that mashes the Molior IFC generator from the Homemaker project, Blenderbim, and some clever non-manifold geometry ideas borrowed from Topologic.

Wherein I stumble through a description of how Homemaker uses Christopher Alexander's Pattern Language to evolve buildings: youtu.be/E7yHDorTw3I

The purpose of this is to get a 'taper' transform that actually works.
The homography transform preserves straight lines and planes, whereas the normal taper transform just makes a horrible mess of 3D objects

Thanks to lots of help, this is now pretty much what I hoped it would be: A big list of patterns from A Pattern Language that can be easily shortened to a small list, it is a single portable file, and prints very nicely.

Unfortunately this Pattern Language companion is really ugly (see picture).

This can be fixed. But what really needs is a little bit of scripting to make it really useful. 4/
