# rhino_shapely_interop

A python package for converting rhino geometry (https://www.rhino3d.com/) into shapely geometry (https://pypi.org/project/Shapely/).

## Installation

```

$ pip install rhino-shapley-interop

```

## Supported Geometry:

1) Rhino Points -> Shapely Points

2) Rhino Curves -> Shapely LineStrings

3) Rhino Breps  -> Shapely Polygon (limited to planer single surface breps)

## Current Limitations:

1) One way (Rhino to Shapely)

2) Rhino is 3D, Shapely is 2D (effectively)

    * Breps are limited to planer single surface breps

    * A shapely plane is defined 

3) InstanceDefinition geometries are ignored (geometry listed in rhino3dm.File3dmInstanceDefinitionTable)

    * Blocks

    * Annotations

## Examples:

See 

1) [`example1.py`](https://github.com/normanrichardson/rhino_shapely_interop/blob/master/examples/example1.py), and [`example3.py`](https://github.com/normanrichardson/rhino_shapely_interop/blob/master/examples/example3.py) for importing from a file

2) [`example2.py`](https://github.com/normanrichardson/rhino_shapely_interop/blob/master/examples/example2.py) for importing from serialized brep

# Development/Contributions
