사용자 지시(2026-09-02) — 로고·서명을 임의로 만들어 표제란에 넣고, 위치·크기는
도각을 고치면 따라오게 하며, 시행청·과업책임자 등은 DB를 넓혀 채울 것.
도각(표제란)
- `00_template_A1.json` 에 그림 자리 2개 추가 — 회사 로고는 용역회사 칸 왼쪽
(316~348 × 20~36mm), 설계자 서명은 설계 칸 아래(638~680 × 17.5~25.5mm).
자리·크기가 **템플릿 좌표로만** 정해지므로 도각을 고치면 그대로 따라옴.
- `_fill_placeholders` 가 그림 자리(`imageData`)의 `{{키}}` 도 채움. 값을 못 구하면
빈 문자열을 남기지 않고 **엔티티째 제거** — 빈 값은 CAD 가 깨진 그림으로 그림.
- `_transform_entity` 가 `points` 배열도 옮김. 그림(로고·서명)과 띠(Hatch)가 이 키를
쓰는데 여태 변환 대상이 아니라 도각을 옮기면 제자리에 남았음.
DB (`011_title_block.sql`, 전부 ADD COLUMN·NULL 허용)
- `projects` — `client_org`(시행청), `pm_user_id`·`field_lead_user_id`·`designer_user_id`
- `companies.logo_path` · `users.signature_path` — 그림은 파일로 두고 경로만 담음
(기존 `storage_path`·`input_files` 와 같은 방식)
- FK 는 걸지 않음 — 사유를 파일 머리말에 적음(소프트 삭제·LEFT JOIN·4환경 공유).
배선
- `_title_block_fields` 가 시행청·과업책임자·분야별책임자·설계자(배정 없으면 소유자)와
로고·서명 data URL 까지 실어 보냄.
- `read_stored_asset()` 신설 — `storage/` 기준 상대 경로의 **파일**을 읽음.
`resolve_stored_project_path()` 는 폴더를 만드는 프로젝트 루트용이라 파일에 못 씀.
CAD 결함 1건 (이번 작업에서 드러남)
- `screenCanvas.drawController.drawImage` 가 `(width, height)` 를 좌표처럼 변환해
화면 오프셋과 y 뒤집기가 섞여 들어갔음 — 그림이 제 자리를 벗어나고 비율이 무너짐.
크기는 배율만 곱하고 자리는 세계 중심으로 잡도록 고침(SVG 컨트롤러와 같은 방식).
- 검증 창구 `__aisloCad.screen(x, y)` 추가 — 세계→화면 좌표. 그림·글자가 제 자리에
그려졌는지 픽셀로 판정할 때 씀.
검증: `pytest tmp/tests/ -q` 135 passed / 0 failed(그림 자리 3건 신규),
`npx vitest run` 87 passed / 0 failed, `check-types`·`build` 통과.
화면 실측(5174, wdw): 표준도 API Text 24개 `{{` 잔존 0, Image 2개가 도각 좌표
(316,20)-(348,36)·(638,18)-(680,26)에 실림. 캔버스 픽셀 판정 — 두 자리 모두 배경색
외 픽셀이 그려짐(로고 88px·서명 64px), 로고 파랑(20,70,140)이 슬롯 안에서만 검출.

Aislo B08 2D Drawing
This directory is maintained as part of the Aislo project and is not connected to an upstream Git repository. It provides the independent browser-based 2D drawing workspace used only by the B08 page.
The drawing engine is based on OpenWebCAD by Bert Verhelst and retains its MIT
license notice in LICENSE.md and public/THIRD_PARTY_LICENSES.txt.
Aislo integration boundary
- Business drawings enter the iframe only as same-origin JSON messages with
type
aislo:b08:load-drawing. - Browser-side DXF/DWG parsing is intentionally excluded.
- DXF, DWG and PDF input/output are separate future modules and require a new dependency-license review before implementation.
Original project description
This is a React-based canvas drawing application that allows users to draw various shapes, such as lines, rectangles, and circles, on a fullscreen canvas. The application also includes features for selecting and erasing shapes, as well as exporting the drawing as an SVG file.
DEMO: https://bertyhell.github.io/openwebcad
Features
- Fullscreen canvas with a black background
- Drawing tools: Line, Rectangle, Circle, measurements
- Zoom and pan
- Eraser tool to delete segments
- Undo and redo
- Choose angle guides
- Draw with snap points for
- endpoints
- midpoints
- intersections
- circle centers
- circle quadrants
- Selection tool to highlight and modify shapes
- Use CTRL to toggle selection
- Use shift to add to the current selection
- drag left, to select by intersecting
- drag right, to select by containing
- Move
- Rotate
- Scale
- Align shapes to each other
- Array copy linear
- Array copy radial
- Import images into the drawing
- Import SVG files
- Export to PDF
- Export drawing as an SVG file
- Export drawing as an PNG file
- Save and load drawings from/to json files
- Select line color and thickness
- Eraser tool to delete segments
Possible future feature ideas (TODO) in order of likelihood
- Eraser tool to delete segments
- Max distance to delete
- Layers for drawing shapes in different layers that can be toggled on or off
- Mirror
- Offset
- Add text
- Ellipses
- Regular polygons (pentagon, hexagon, etc)
- Combine lines into a polygon
- Explode polygons into lines
- Polygon circumference
- Polygon area
- Chamfer, Round corners
- Draw with snap points for
- circle tangents
- nearest point on line
- prioritize certain snap points over others (eg: midpoint over nearest)
- Edit existing lines and circles by dragging endpoints/middle points
- Hatching and fill areas
- gradient fills
- Import DXF files
- Import DWG files
- Export to DWG
- Export to DXF
- Export drawing to ASCII code
Maintenance
- replace react with webcomponents (Lit)
Technologies Used
- TypeScript
- JavaScript
- React
- NPM
- HTML canvas
- SVG
- SCSS
- Tailwind CSS
