Stop document saving

[j.han97]

Hi all,

Due to security concern my team should not upload sensitive data to cloud storage. Therefore I wrote an add-in to monitor the Application.documentSaving event. According to the documentation, 

'You can set the isSaveCanceled property of DocumentEventArgs to true to cancel the document save.'

But when I test this add-in, the saving process is not interrupted at all. The problem is, there is no 'isSaveCanceled' property in both the documentation and the code hint in VSCode.

The sample add-in is posted below. Your help is highly appreciated!

#Description-This add-in is used to disable upload/saving any file to Fusion 360 cloud server

import adsk.core, adsk.fusion, adsk.cam, traceback

class documentSavingEventHandler(adsk.core.DocumentEventHandler):
    def __init__(self):
        super().__init__()
    
    def notify(self, args):
        _app.log('Detected document saving')
        eventArgs = adsk.core.DocumentEventArgs.cast(args)
        #Tried with/without firingEvent
        ##eventArgs.firingEvent.isSaveCanceled = True
        eventArgs.isSaveCanceled = True
        

_app: adsk.core.Application = adsk.core.Application.get()
_ui: adsk.core.UserInterface = _app.userInterface
_handlers = []

def run(context):
    try:
        _app.log('Addin is running')
        onDocumentSaving = documentSavingEventHandler()
        _app.documentSaving.add(onDocumentSaving)
        _handlers.append(onDocumentSaving)
    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

def stop(context):
    try:
        _app.log('Stop addin')
    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Hi @j.han97 .

I also tried several text commands, but I could not abort the save.

I think it's a bug.

This is a case where a behavior was specified but either because of technical issues or because of time was not implemented and the specification, which becomes the documentation, was not updated to reflect the actual behavior.  There is a bug, but the bug is with the documentation.

Hi @BrianEkins ,

Thank you so much for your answer. Based on your knowledge on Fusion 360 API, is there any way to prevent files from being uploaded to cloud server? This is a major security concern (at least for my team) while dealing with sensitive information. (Not that we thought that Fusion 360's cloud server is unsafe, but the fact that the data will be outside of our control is already a serious risk to us)

In addition, you mentioned that the reason of not implementing this feature (property) is due to either technical/time limitations. Is it something on the working list of the development team so that we can expect it to be available soon in future versions of Fusion 360?

@j.han97 .

By using the commandStarting event, I was able to prevent the file from being saved in online mode.

import adsk.core

import traceback

_app: adsk.core.Application = adsk.core.Application.get()
_ui: adsk.core.UserInterface = _app.userInterface
_handlers = []

class MyCommandStartingHandler(adsk.core.ApplicationCommandEventHandler):
    def __init__(self):
        super().__init__()
    def notify(self, args: adsk.core.ApplicationCommandEventArgs):

        if args.commandId != 'PLM360SaveCommand':
            return

        global _app, _ui
        if not _app.isOffLine:
            _ui.messageBox('Saving in online mode is stopped by the add-in.')
            args.isCanceled = True

def run(context):
    try:
        global _app, _ui, _handlers
        _app.log('Addin is running')

        onCommandStarting = MyCommandStartingHandler()
        _ui.commandStarting.add(onCommandStarting)
        _handlers.append(onCommandStarting)

    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

def stop(context):
    try:
        global _app
        _app.log('Stop addin')
    except:
        if _ui:
            _ui.messageBox('Failed:\n{}'.format(traceback.format_exc()))

Hi @kandennti,

This is a brilliant way I have never thought of! Thank you and I will test it out soon.
