I am developing a Python add-in for Fusion 360 to automatically update older drawings with new title blocks. The intended workflow is to add a helper sheet from an existing drawing master with the correct title block, switch back to the original sheet, replace its old title block and delete the helper sheet.
Launching native drawing commands works, but I cannot find any public API objects or methods to directly access drawing sheets or title blocks. In particular, I do not see a documented way to switch the active sheet, programmatically select a specific existing title block, or reliably delete the helper sheet after it is created. Because of this, I can only build a guided workflow that opens the native dialogs, but not a fully automated solution. Is there a supported API approach for this, or are these drawing/title block operations currently not exposed in the public Fusion 360 API?
