You can add EA material into any Word document using eaDocX.
In the EA top menu, select Specialize | eaDocX | Open Word document. This opens a browser window where you can select an existing Word document.
When eaDocX opens any Word document it first looks for the document Profile. If your document has content in it that's been generated in eaDocX before, it will pull in the eaDocX profile information embedded in that document and you'll be able to check or edit it in the Profile tab. In the case of a non-eaDocX document, which does not have a profile defined, eaDocX will treat it as though it's a new document. You can insert sections in the same way you would in a fresh document, and generate and edit the profiles as normal.

The eadocX Insert menu - either hover over or click the Insert tab to show options.
Right-Clicking in the model browser to add to document will show you all the documents you have open in eaDocX and let you choose in which you want your data. New Sections will be created wherever your cursor is in the Word Document.
