View List in an other application

Hi to all the community,

I have a CAD program using lists to render.
I need to render the models in an other application.

I need one of:

  • Save the list in a file and read it from my opengl App.
  • clone buffer data and access it from my App
  • any other Idea is well accepted

This is my first post,
Thanks in advace,
Peppe.
