crisscross-kit 1.1.0

Unified CAD and scripting packages for megastructure design, handle library generation and visualization.

Crisscross Kit Python Library

#-CAD was developed alongside a Python API (crisscross) that can be used to manipulate megastructures programmatically. They share the same file format and can be used interchangeably. The Python interface provides more flexibility and customizability, at the cost of a steeper learning curve. We have also developed our own custom-made algorithm for creating an orthogonal assembly handle library, which is accessible via the orthoseq_generator package. Both packages are installed together with the below instructions.

Installation and Requirements

• The Python package was developed using Python 3.11. Other versions of Python should also work, but it is recommended to use 3.10+.
• To install the python interface, simply run the below in your environment of choice:

pip install crisscross_kit

• (Optional), if you would like to be able to generate 3D graphics or 3D blender files for further customization, you need to install additional dependencies:

pip install crisscross_kit[3d]
pip install crisscross_kit[blender]

• To be able to use the orthoseq_generator, you will need to separately download and install NUPACK 4.x after installing the crisscross_kit. Please follow their instructions here for installation.

Developer Installation

• To install the python interface and allow for changes to the code to be immediately updated in your package, clone this repository and navigate to the crisscross_kit directory. Next, run:

pip install -e .

• You may also choose to install the package dependencies using other package managers, such as conda. The requirements are hosted in requirements.txt.
  • To install with pip run the following: pip install -r requirements.txt
  • For conda run the following: conda install -c conda-forge --file requirements.txt
  • For PyVista, install the dependencies from requirements_pyvista.txt.
  • For Blender, simply run pip install bpy

Usage Guides and Documentation

The documentation for both the designer library (crisscross) and the orthogonal sequence generator (orthoseq_generator) are provided within separate readmes:

• For the crisscross library, details are provided here.
• For the orthogonal sequence generator, details are provided here.

Building for PyPI

• For developers looking to build the package for PyPI, you can use the following commands from the crisscross_kit directory of the repository:
• First, make sure the build tools are installed:

pip install build twine setuptools-scm

• Next, build the package:

python -m build

• The build command will create a dist folder containing the .whl and .tar.gz files for the package. These can be uploaded to PyPI using:

twine upload dist/*

• You will need to have a PyPI account and set up your credentials in ~/.pypirc for the upload to work (you will also need to be set as a collaborator on the crisscross_kit project too).
