Have you tried looking into ProE API? The one that allows programmers to update drawings? If you have and could not find anything, I suggest the following:
Please consider Plot Service from Etrage LLC to convert your Pro/ENGINEER drawings to DXF. We have versions of Plot Service that work with Pro/INTRALINK 3.x, Windchill or on a file system. Plot Service has three operating modes.
1. Automatic monitoring of Pro/INTRALINK or Windchill for Lifecycle or Revision changes and at Check-in
We have an immaculate solution for meeting your requirements. Please take a look at the attached doc and let us know if you would like to have a live demo.
We have a product that will do this and other things that are frequently asked for like converting models from one format to another i.e. Pro/E to Catia or UG etc.
Fishbowl has out of the box products too (<u>www.fishbowlsolutions.com</u>), but I don't fully understand your requirements or use cases so I can't recommend any possible solution without knowing more.
Feel free to contact me if you are interested in discussing the business problem you are looking to solve. We can surely help you with either a standard product or custom solution depending on your situation.
Also, if you are attending PTC User in Orlando this coming week then please stop by our booth # 409.
