small-2Dto3D-cad-backend

This backend makes 3D model from 2D projections. 2D projections are expected to be made up only of edges and points i.e. without any faces.
This project be used to visualize 2D blueprints in 3D or to check their consistency.
Frontend is small-2Dto3D-cad-frontend, go there for screenshots.

How to run it

Run backend

Install dependencies

pip install -r requirements.txt

Run in local with hot reload and no CORS

APP_ENV=local python web.py

Run prod like

gunicorn --workers 4 --bind 127.0.0.1:8000 web:app

You can also build and run the docker (rquires docker installed)

docker build -t small_2Dto3D_cad_backend . && docker run -p 8000:8000 small_2Dto3D_cad_backend

Run tests

All tests should be green

pytest

What's next?

  • Remove shapely which is a 2D only library which is not very helpful (and is misleading)
  • Tests dandling points and edges
  • Improve frontend UX (and UI thanks to external contributors)
  • Maybe reconstruct faces directly from reconstructed edges (we can't have faces in projections)
