Hi Jacob,
Lots of fun, nice work…
I noticed a slight typo, here’s how I think it should be…
If this is the way the OP wants to go, here’s a version based brick dimensions… It’s still quite rough and would need work to accommodate openings, joining walls etc.
This example is 10m x 8m… When I load it in, it generates an RVT that’s about 10meg bigger than an empty one.
Hope that’s of interest,
Mark
