Automated generation of a simplified drive shaft
This script creates a new CATPart including parameters, design table, rules and checks (Knowledge Advisor).
The script runs with CATIA V5 Release R15 (R14 needs minor changes in code). It supports user interface languages english and german. The code is well commented, but comments are all in german. For some more informations, look at the short documentation (german).

CATIA V4 and CATPart to VRML Converter
A CATPart to VRML Batchconverter:
The next example uses the \"CATIA V5 Interfaces Object Library\" to
connect to CATIA V5, open a CATPart and export it to VRML. You can do
that with other formats like IGES, STEP, … too (if you have the
licence).
You need Python and Pywin for this example and have also running CATIA V5:

A CATIA V4 model to VRML Batchconverter:
You can`t do this interactive in CATIA V5 but with Python. Simply
open a CATIA V4 model and export it to VRML (I did this with R14):
