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.
