- ui-state.ts ribbonCollapsed · Ribbon.tsx 접기 단추 · 탭 누르면 펼침
- App.css --cad-ribbon-height 를 Toolbar.tsx 가 접힘 때 26px 로
- aislo-drawing-bridge.ts load 곁값 ribbonCollapsed 받아 반영
- cad_host.ts CadLoadExtra 칸 추가 · M02_MasterTemplete_Drawing.ts 가 true 로 보냄
(도면 양식 · 구조물 도면 둘 다 이 파일 한 곳을 씀)
- B07 은 곁값을 안 보내 펼침 그대로(코드 확인 · cad.load 호출 둘 다 5번째 인자 없음)
- 구조물 편집 머리 제목(② 열 머리 글)은 이미 다른 창이 끝냈음(commit 65f43ca0) — 손대지 않음
검증: CAD 빌드 · 루트 npm run typecheck · M02 시험 18개(구조물·도면 영역) 통과 ·
ORCA 로 도면 양식(00_template_A1) 처음 접힘(26px) → 단추로 펼침(122px) 확인.
구조물 도면(rv 등) 은 서버가 만드는 빈 문서에 `layers` 키가 없어 CAD import 단계에서
조용히 실패(레이어 접근 에러) — 리본 접기와 무관한 기존 결함 · 손대지 않음(브레인에게 보고).

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

- 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
