The COMPAS framework

build GitHub - License PyPI - Python Version PyPI - Latest Release Conda - Latest Release DOI

The COMPAS framework is an open-source, Python-based framework for computational research and collaboration in architecture, engineering and digital fabrication.

The main library consists of a core package (compas) and several additional packages for integration of the core functionality in CAD software (currently: compas_blender, compas_rhino, compas_ghpython).

The core package defines all real functionality. The CAD packages simply provide a unified framework for processing, visualising, and interacting with geometry and datastructures, and for building user interfaces in different CAD software.

Getting Started

The recommended way to install COMPAS is to use Anaconda/conda:

conda config --add channels conda-forge
conda install COMPAS

But it can also be installed using pip:

pip install COMPAS

To verify your setup, run the following:

python -m compas
