It's built on the Open Cascade geometric kernel and allows for the creation of complex models using a simple and intuitive python syntax. Build123d can be used to create models for 3D printing, CNC machining, laser cutting, and other manufacturing processes. Models can be exported to a wide variety of popular CAD tools such as FreeCAD and SolidWorks. Build123d could be considered as an evolution of [CadQuery](https://cadquery.readthedocs.io/en/latest/index.html) where the somewhat restrictive Fluent API (method chaining) is replaced with stateful context managers - e.g. `with` blocks - thus enabling the full python toolbox: for loops, references to objects, object sorting and filtering, etc. The documentation for **build123d** can found at [readthedocs](https://build123d.readthedocs.io/en/latest/index.html). There is a [***Discord***](https://discord.com/invite/Bj9AQPsCfx) server (shared with CadQuery) where you can ask for help in the build123d channel.
