- DXF -> 도각 JSON 변환 엔진 신설 (ezdxf) — 선·폴리선·원/호/타원/스플라인 평탄화·글자·점 변환, 블록·치수는 분해, 해치 등 미지원 요소는 제외
- DWG 는 ODA File Converter(.env ODA_CONVERTER_PATH) 경유 변환, 미설치 시 DXF 저장 안내로 폴백
- POST /{project_id}/frame-template/import 신설 — 파일을 편집 화면용 도면으로 반환(저장은 기존 [완료] 경로 유지), 20MB·2만 도형 상한
- 도각 편집 띠에 「파일 불러오기」 추가, 자리표 팔레트 신설 (글자 14종·그림 4종을 도면 중앙에 배치 후 이동)
- CAD 텍스트 선택 시 회색 점선 외곽선 표시 (출력물에는 미포함)

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
