What is PythonOCC? PythonOCC is an Open Source (LGPL) Python-wrapper for OpenCASCADE. So what is OpenCASCADE (OCC)? This is an advanced Open Source (custom license) modeling kernel, comparable to commercial engines, such as ACIS or Parasolid, which are used in quite some commercial CAD programs. When you want to develop CAD software, you could use OCC and write programs in C++. And why using Python? With this wrapper, you can create CAD and geometry scripts in Python, which is an interpreted Object-oriented scripting language. You can write almost "on-the-fly" and seriously reduce the implementation effort, by skipping the compiling-phase. You can even interact with a running program in the Python interpreter. Want to read more about this? The OpenCASCADE official website  (currently Linux and Windows are officially supported) The PythonOCC website/blog  (beware that the core of the actions happen in the development repositories). So far so good. Now the nasty, techn
