pythonocc is a python library whose purpose is to provide 3D modeling features. It is intended to developers who aim at developing CAD/PDM/PLM applications.

Latest release : pythonocc-core 0.18.1 (december 2017)

Download/install binaries

pythonocc provides precompiled conda packages (they depend on third part libraries made available from the dlr-sc and conda-forge conda channels) for python 2.7, 3.5 and 3.6. This will get you up and running in minutes whether you run win32/win64/linux64/osx64. Here is an example for python 3.5:

# install pythonocc in the active environment with python 3.5
conda install -c conda-forge -c dlr-sc -c pythonocc -c oce pythonocc-core==0.18.1 python=3.5

Just replace "3.5" with "2.7" or "3.6" in the previous command to fit with your prefered python version.

Download pre-releases/development binaries

Each time a change is committed to the github repository, related binaries are uploaded to the tpaviot anaconda channel, labelled with the git development branch name.

oce and pythonocc

The basis of pythonocc is python wrapper for the oce C++ library / CAD kernel, aka pythonocc-core. pythonocc-core version number correspond to oce library releases its wrapping.

For example; the current pythonocc-core release, 0.18, requires any of the OCE 0.18.x releases. Here, the Major version name of either OCE or pythonocc-core release is 0, the Minor version is 17 and the Patch version is (optionally) x. pythonocc-core can be built with any OCE version that has a corresponding Major and Minor version number. For example, pythonocc-core 0.18.1 can be built with OCE-0.18.1.
