Place 3D objects and modular kit pieces from measured geometry: floors, walls, facades, pipes, alcoves.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Spatial Placement in Summer Engine Place from measured geometry, never from guesses about size or facing. Use Starcast as spatial evidence, not as an automatic placement solver. Make a reasonable transform from scene intent, inspect the result, then correct only the axes that the evidence shows are wrong. Every tool below is already shipped. Arguments, result shapes, limits and the engine ops behind them: [references/kit-placement-tools.md](references/kit-placement-tools.md). ## Choose the tool | Question | Tool | |---|---| | Size, origin, front/back plane, pipe ends of a piece not yet placed? | `summer_inspect_asset` | | Place one piece at an exact pose | `summer_instantiate_scene` with `position`, `rotation_degrees` | | Place many pieces, read the receipt | `summer_batch`, placed `InstantiateScene` ops, `receipt: "summary"` | | Next module edge to edge, next storey on top | `summer_place_adjacent` | | Pipe, lamp, AC unit or sign on a wall | `summer_attach_to_surface` | | Clamps, braces, posts or windows along a line | `summer_repeat_along` | | Pipe or duct end to end | `summer_connect_ports` | | Surface and normal in front of a point | `summer_raycast` | …

How to install
mdr add summerengine/summer/spatial-placement@sha256:50919318e9f07e1eThe line at the top of this page pins the label git:20261016.e9d6e70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
