cut-craft

Python package

Note that this package is written for Python 3, however requires Python 2 compatibility for Inkscape integration.

The cutcraft package contains components in the following categories:

Folder	Description
core	Core components (point, line etc).
platforms	Platforms used to construct shapes (circular etc).
shapes	Fundamental 3D shapes (cylinder, cone, sphere etc).
supports	Vertical supports to hold the shape levels apart.

Core

Module	Description
point	A 2D point with x and y coordinates.
rectangle	Two points defining topleft and bottom right for a rectangle.
trace	An ordered collection of points.
part	A collection of one or more traces.
line	A type of trace with two points defining the start and end of the line.
circle	A type of trace with points defining a circle.
neopixel	A type of trace with the points defining a cutout suitable to fit a variety of NeoPixels.

Shapes

Module	Description
shape	The core 3D functionality for a shape.
cone	A cone shape.
cylinder	A cylinder shape.
sphere	A 3D spherical shape.

Note that the fundamental shapes listed above can be used flexibly considering the number of circle segments can be specified. For example a cone with 4 segments becomes a pyramid, and a cylinder with 4 segments becomes a cube.

Supports

Module	Description
support	The core support structure functionality.
pier	A pier like support to hold shape levels apart.
face	A solid face to support shape levels.

Python 2 vs 3 Compatibility

The initial aim was to develop only for Python 3, however Inkscape currently uses Python 2 as the default interpreter for extensions. As a result, the following should be noted while reviewing the code:

1. The calls to super() are written in a way that works with both versions of Python.
2. The math.isclose() function is not available in Python 2 so a local version has been created in util.py.
