How can add a document A4?

Hi @femkeblanco, the documentation is wrong. The first argument should be a document preset string. Valid strings are the names of the document profiles saved in your system, default or created by you. These are the same document profiles you see when you create a New Document by hand.

this is the correct info

Documents.addDocument (startupPreset: string , presetSettings: DocumentPreset , showOptionsDialog: Boolean 😞 Document Adobe Illustrator 25 Type Library Create a new document from a preset. startupPreset: Data Type: string The name of a startup document preset. presetSettings (optional): Data Type: DocumentPreset Custom settings to apply to the preset. showOptionsDialog (optional): Data Type: Boolean If false, do not show Options dialog.

I recently noticed the documents.addDocument() function in the documentation is wrong. It's a miracle that it works as written above.

the addDocuments() first argument should be a document preset, not ColorSpace. ColorSpace is the first argument of the documents.add() function

so, technically, it is possible to add a default font to new documents created as long as your first create a New Document Profile.

then in your script

var docPreset = new DocumentPreset;

// ....add preset properties if you want to override the deafult "profile" document

var docProfile = 'myProfile'; // or default "Print" or "Web"

var idoc = app.documents.addDocument(docProfile, docPreset, false);

it doesn't work perfectly as it seems to always create CYMK documents, but at least that can be overwritten with docPresets properties.
