Not a LOT of progress to report, but I did spend some time cleaning up the templates that I use to make walls and posts. I'll continue to beef up my collection of templates, making kitbashing a quicker process for the standard pieces. After cleaning up the templates for posts, it only took 10 minutes (maybe less) to make all the standard height walls (2-way, 3-way and 4-way with and without angle support).
I've already got 6" walls with the castle texture applied, so I'm going to try to make 3" walls, and destroyed walls today, so that tonight I can let my robocutter prep a bunch of stuff. If all goes well, I'll have a tiny test build of a single-story mini-castle.
