To open a document use the open(filepath) method or the openDocument(filepath, [hidden=False]) method of the FreeCAD application.

These methods create and return a document and load a project file into it. The filepath argument must be a string pointing to an existing file. If the file doesn't exist or the file cannot be loaded an I/O exception is thrown. In this case the created document is kept, but will be empty. If hidden=True is used, the document won't be displayed in the GUI and no tab will appear for it. This allows performing automatic operations on a document and closing it without disrupting the user interface.

For a scripting example see Std New.
