Owner directives 2026-07-14~15: run the DWG pipeline; split floorplan into DWG and JPG tabs. - tools/cad/dwg_extract.py: DWG(LibreDWG dwg2dxf) -> DXF -> layer inventory / keyword extraction / grid-label anchor detection (ezdxf, recover fallback) - tools/cad/render_hall_png.py: render hall-band crops from the K1 combined plan+trench drawing (x0=293.5m, width 171m, Y bands 80.1m + 63m pitch, single load -> multi-crop). Real trench layout confirmed: 7 horizontal runs at ~9m pitch + central feeder (differs from assumed 6m grid seed - V61 later) - public/media/floorplans/dwg/hall1..5.png: K1 hall underlays (3m margin crop, deterministic calibration from render params) - Editor left panel new tool group with JPG/DWG tabs; DWG disabled for halls without CAD render yet (K2 pending). Canvas switches url+region. - docs/analysis/cad-extraction.md: pipeline findings, limits (A3002 LibreDWG crash, band-to-hall numbering direction to confirm), next steps Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

"""CAD DXF → 홀별 DWG-탭 언더레이 PNG 렌더 (ezdxf drawing addon + matplotlib).
|
|
|
|
제1전시장 `전기,설비 트렌치.dwg`(평면+트렌치 통합 도면) 기준:
|
|
- 구조 그리드 Y 라벨이 63m 피치(y=80.1 시작) = 홀1~5 Y밴드
|
|
- X 원점·폭은 인자로 조정(렌더 결과를 눈으로 검증하며 캘리브레이션)
|
|
|
|
사용:
|
|
python tools/cad/render_hall_png.py <dxf> <hall_no 1~5 | 1-5> <x0_m> <width_m> <out.png|outdir> [margin_m]
|

예:

python tools/cad/render_hall_png.py k1_trench.dxf 1 293.5 171 hall1_dwg.png 3
