Rules for modeling sloped, twisted and warped timber structures from straight members: ruled surfaces, per-bay framing, plane-cut legs and slab-exact clipping.
- Modeling a hypar wall or roof from straight timber members
- SKILL.md covers Overview, Warped surfaces, Cutting rules that only bite… and Members meeting sloped surfaces, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Framing hips, valleys and pitched members that meet at angles
What it does
A set of modeling rules for design briefs that leave the orthogonal grid but still use straight timber stock: pitched members meeting at angles, hips and valleys, hypar walls and roofs and deconstructivist forms. The guiding idea is to build warped and angled things from straight convex pieces cut by planes, so the geometry stays buildable and the overlap check stays valid. The parent project describes an AI agent that turns design briefs into Python code defining a building.
For warped surfaces, the first question is whether the surface is ruled, and a hyperbolic paraboloid is modeled as a bilinear patch between two straight segments, with rulings carrying studs and rafters and cross rulings carrying boards. The rules advise short stock on twisting surfaces, framing fitted per bay, segmented or narrower continuous members, and reporting each member's out-of-plane residual as buildability information. Other rules cover legs cut by two planes and slab-exact clipping with shifted cut planes. The excerpt is cut off in the cutting-rules section.
When your agent uses it
- Modeling a hypar wall or roof from straight timber members
- Framing hips, valleys and pitched members that meet at angles
- Standing a tilted object on a warped surface without bent members
- Checking how far members deviate from flat on a twisted surface
Example prompts
- “Model a hypar roof from straight rafters and cross boards, and report the out-of-plane residual per member.”
- “Frame a twisted timber wall in short stock with joints on the support centre lines.”
- “Cut the legs of a tilted frame so they stand on a warped surface, using two planes for each leg.”
What it can do on your machine
Read from SKILL.md and the folder at commit 2c9715b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Non-Orthogonal Timber Geometry loads about 1.2k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 699 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 699 words (~1,172 tokens).
“Leaving the orthogonal grid does not mean leaving straight stock. Almost every rule here is a consequence of one idea: build warped and angled things from straight convex pieces cut by planes, so the geometry stays buildable and the overlap…”
