Open CASCADE version 5.0
More efficient, more productive... and still Open Source!

A more efficient version
This new major version includes new features such as:
  • a new version of Boolean Operations increasing algorithms' reliability, including singularity cases,
  • an e-Viewer providing a web-browser 3D visualization service,
  • a Document Browser making development with Open CASCADE Application Framework (OCAF)
    more efficient,
  • a Class Browser giving a better view of the Open CASCADE classes organization.

    A more productive version
    The improvements allow users to develop their scientific and technical projects with greater efficiency:
  • more than 500 corrections since previous version
  • a 'step by step' procedure assisting the user to install Open CASCADE platform, environment and
  • highly extended documentation, especially on Shape Healing and Data Exchange modules.

    As a strong actor of the open-source movement, OPEN CASCADE S.A. maintains its engagement in its
    business model: more than 2700 days were invested in this new major version. Like previous versions, Open CASCADE version 5.0 is based on the Open CASCADE public license
    providing users the complete freedom to distribute their own derived developments and products.

    To increase development teams performance, OPEN CASCADE S.A. offers a wide range of support
    services including standard or specific trainings, e-learning sessions as well as a set of 'a la carte' support packages allowing to fit particular needs of development teams and to benefit from Open CASCADE S.A. expertise.
