CadQuery

CadQuery is an intuitive, easy-to-use Python library for building parametric 3D CAD models. It has several goals:

  • Build models with scripts that are as close as possible to how you’d describe the object to a human, using a standard, already established programming language.
  • Create parametric models that can be very easily customized.
  • Output high quality CAD formats like STEP and AMF in addition to traditional STL.
  • Provide a non-proprietary, plain text model format that can be edited and executed with only a web browser.

    • CadQuery 2 is based on OCP, which is a set of Python bindings for the open source OpenCascade modelling kernel.
