Anything you put into Dramatica you can export via the reports. You are correct in identifying that Dramatica is a place to develop your ideas and materials, but eventually you will write the finished work in your word processor.
Most of Dramatica's topics ask you to describe story elements in a single place. However, those descriptions may be broken down into bits and pieces which are sprinkled throughout your story. How you use what you've written in Dramatica in your finished work completely depends on what you've written.
Some writers use Dramatica to jot ideas and notes--just enough so that they know how they're going to illustrate the story points. When it comes to writing, they use their notes as guidelines but do not incorporate much of the material itself.
Other writers go into great depth in their descriptions. When it comes to writing the finished work, they copy and paste portions of the materials they've written which become part of the finished work itself. These are just two of the many ways that Dramatica users work with the material they've developed in the Dramatica software.
