- state.setActiveLayerId(): 잠금 도면층(도각·원지반) 요청은 잠금 아닌 첫 층으로 돌린다. 브리지·자동백업 복구·JSON 가져오기·도면층 패널·리본이 모두 이 함수를 지나므로 가드를 한 곳에 뒀다. 잠금 아닌 층이 없으면 요청값 유지. - RibbonWidgets: 「현재 도면층」 목록에서 잠금층을 뺀다(현재 층이 잠금이면 유지). - Cover 엔진: 표지에 잠금 아닌 「주기」 도면층을 실어 덧그릴 자리를 만든다. 표지는 엔티티가 전부 도각(잠금)이라 가드만으로는 그릴 곳이 없었다. - state.resetUndoBaseline(): 도면 적재를 되돌리기 바닥으로 세운다. 첫 Ctrl+Z가 도면을 싣기 전 빈 상태로 되돌아가 화면이 백지가 되던 결함을 닫는다. - debug-hook: 검증용 snap() 창구 추가. state.test.ts 3건 신규.

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
