A python module to access the CATIA Measurable object.

Project description

alpha software

This is alpha software. All the test cases and examples work but there will be many issues outside of the test framework. The CATIA com interface is huge and I’m currently just attacking the items I think will be most useful. The framework is in place for others to contribute so if you know CATIA and python please do contribute. Bonus points for adding tests too.

I have limited access to CATIA licences / workbenches I so will not be able to support those I can’t test. If your company would like support for additional workbenches adding to pycatia and can provide a license please contact me.

Why was it made?

pycatia was initially created to access the CATIA Automation Measurable object and it’s methods without the need of visual basic / CATScripts.

Some of the methods can be accessed directly using the pywin32 module but there are a number that just simply won’t work using python. There are several questions on stack overflow and the pywin32 mailing list regarding this. But, they fail to provide any working examples with the Measurable object in python.

pycatia accesses these methods by running VBA scripts using the Dispatch(‘CATIA.Application’).SystemService.Evaluate() function and passing a public function to it. Otherwise, pycatia uses the VB method directly but exposes it within the same python class.

There is now further functionality available which can be seen by looking at the examples provided and reading the API at pycatia.readthedocs.io.

  • CATIA V5 running on Windows.
  • see requirements.txt

Contributing

If you would like to help contribute to pycatia you should start by looking at the contents of the file v5automation-autogenerated.7z contained within this repository.

This archive was created by scraping through the contents of the V5Automation.chm help file to re-construct all the classes and methods for python. It’s largely complete but won’t work out the box without some tweaking. But these files should be the basis for any pull requests. They will save you sometime and effort and ensure some consistency for the project.

If you have written a script using pycatia you would like to share you can:

Running The Tests

On the first run, during the running of the tests, the test suite will create the CATIA drawing, products and part it requires to run in the folder tests/cat_files.

CATIA V5 should already be running and have NO documents already open.

To run the tests with coverage (-v is verbosity):

py.test -v --cov-report term-missing --cov=pycatia

To run a specific test:

py.test -v tests/test_product.py::test_move

To stop tests running after first failure.

py.test -vx
