dwg2svg

A browser tool for turning an SVG drawing into an AutoCAD-style DXF block — click a base point on a canvas, set the attributes, and get real DXF entities out the other end.

01Highlights

  1. Three tiers with one job each: a React canvas for picking, an Express API for projects and attributes, Python for the geometry.
  2. The conversion is real — `ezdxf` 1.4.3 with `lxml` and `Shapely`, parsing the drawing and writing DXF entities rather than wrapping text.
  3. A standalone Flask service on `waitress`, deliberately kept apart from the Node backend.
  4. The base point is chosen by clicking a 1200×800 canvas, then converted from screen coordinates into DXF space.
  5. Projects and attribute definitions are CRUD'd server-side, so a block template is defined once and reused.
  6. A `sandbox/` with sample `.dwg` and `.dxf` files plus run logs — which is how the geometry bugs actually got found.
