Hi Christian,
You can create a new document based upon an existing DOT-template with DocIO by using the following code snippet:
[c#]
WordDocument document = new WordDocument();
//Opening DOT-template
document.Open(@"..\..\Data\Essential DocIO.dot");
//Add a new section to the document.
IWSection section = document.AddSection();
//Adding a new paragraph to the section.
IWParagraph paragraph = section.AddParagraph();
//Insert Text into the paragraph
paragraph.AppendText( "Hello World!" );
//Saving the document to disk.
document.Save("Sample.doc");
Here is the sample for your reference:
