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
