This is the tool O2_CADtoTGeo.py which translates from geometries in STEP format (CAD export) to TGeo.
To use the tool, setup a conda environment with python-occ core installed. The following should work on standard linux x86:
# -) download miniconda into $HOME/miniconda (if not already done)
if [ ! -d $HOME/miniconda ]; then
curl -fsSL https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-aarch64.sh -o miniconda.sh
bash miniconda.sh -b -p $HOME/miniconda
fi
# -) source conda into the environment (in every shell you want to use this)
source $HOME/miniconda/etc/profile.d/conda.sh
# -) Create an OCC environment (for OpenCacade)
conda create -n occ python=3.10 -y
conda activate occ
# 3) Install OpenCascade Python bindings
conda install -c conda-forge pythonocc-core -y
# 4) Run the tool, e.g.
conda activate occ
